Troubleshooting/QA
1: What type of speakers work best with TB1 OD Amplifier?****
– TB10D works great with any 2-8 Q passive speakers.
Note: please know that the TB10D amplifier is for passive speakers, not for
powered speakers and subwoofers.
2: Why does the TB1 OD make serious noise when used together with a
radio?****
– A common feature of Class D power amplifiers is that they can cause serious
noise when used with a radio, so we do not recommend using the TB10D with a
radio or too close to it.
3: Can I connect a turntable to the TB1 OD amp, why is the volume
extremely Low?****
– As the turntables do not have a built-in preamp, you need to add an external
phono preamp before connecting TB10D.
– As for the turntables which have a built-in preamp, you need to switch the
preamp on before connecting TB10D.
4: Why does my power indicator not light up?****
– Please check that the AC power cord is securely connected to the power
supply and to an AC power outlet.
– Please check that the AC power outlet is supplying power, make sure the
power LED on the power supply will stay on.
– Please replace another power supply and try it again. 18-48V DC power
supplies are suitable.
– If you make sure the power supply is defective, please contact us for an
exchange.
5: Why does the sound is cracking or make a lot of electric noise?****
– Please make sure all the cables are completely pushed into the devices, the
incomplete connection will cause this cracking.
– Please remove all the inputs and then check whether the cracking noise
disappears or not, the cracking may be from the audio source or input cables.
– If you are not using the original factory standard power supply, please
replace the power supply before testing. Many power supplies in the market
have large interference coefficients, which will cause a lot of current
sounds.
6: Can I use headphones with this product?****
– No, the TB10D cannot be connected to headphones and only supports passive
speakers.
7: Why there is no voice from my amplifier?****
– Please check whether the cable of the power supply is connected to TB10D and
whether the power indicator is on.
– Make sure the TB10D indicator light is on when the power is turned on.
– Please check that the TB10D and your source components are turned on and not
set to minimum volume, if possible replace your source and test again.
– Check that the wire connections from the audio source to each speaker in the
amplifier are connected correctly.
– Please check that the cable is not loose, or damaged. An incomplete
connection is one of the main reasons for no sound.
8: How much power does this use in standby mode? Can this amp be left on
all the time?****
– This is the class D amplifier, it will cost very low power when it is in
standby mode. It can be connected all the time and it is safe without power
consumption.
9: Sound quality is not good?****
– Make sure all the cables are fully connected.
– Adjust the treble and bass control of the power amplifier to achieve the
right tone.
– Please try to change the sound source and cables to test.
10: Should I unplug the power cord?****
– If the item will not be used for a long time, please unplug the power plug
to prevent the item from being burnt due to a lightning strike.
11: Can I bridge channel 1 and channel 2 to get 600watts?****
– NO, this amplifier can’t be bridged.
12: How can I connect TB10D to the TV?****
– Because the TB10D has an RCA input, it can be connected to a TV.
13: Will I be able to turn up the volume using my TV controller or will
I need to adjust the volume manually?****
– Technically speaking the TV’s remote control does not control the volume of
the amplifier and adjusting the volume of the amplifier requires the manual
use of the amplifier’s volume control buttons, but the size of the signal from
the TV to the amplifier will affect the sound output of the amplifier.
14: Why the sound cut in and cut out?****
– Try to reduce the sound of the sound source.
– Try to change the audio source to test.
– Reduce the volume of the treble and bass knob on the TB10D.
– Ensure that the positive and negative poles of the speaker output do not
touch together. Some relatively large banana plugs are easy to touch together
and cause a short circuit.
15: Can I Connect a Subwoofer to the Fosi Audio Amps?****
– If you bought subwoofer amps from Fosi Audio or a 2.1 channel amplifier(the
amp that with sub output), you can connect to a subwoofer, but if you got the
2.0 channel amp, you can’t connect to the subwoofer.
16: Can I exchange the power supply that comes with the amplifier to get
more power?****
– The TB10D comes with a 32V 5A power supply, it’s enough for most bookshelf
speakers, but if you want to get more power, you can exchange the power
supply, the voltage range is DC18-48V, you can use 24V SA or 32V 6A power
supply.
17: Can I take the TB10D to other countries?****
– Yes, the wide voltage AC 110-240V for power input can be used in any
country. You only need to match the power cord adapter of the corresponding
country.

Introduction
The Jensen Power series of amplifiers were designed to meet or exceed the
CEA-2006 test standards. These new standards give all participating
manufacturers (and many don’t participate) a baseline when comparing
amplifiers of similar power output. The CEA Power rating protects you, the
customer. “Power is power – it doesn’t matter wh o makes it,” is not always true.
What does matter is whether the power can be produced in the first place. The
RMS rating is the true power you are getting. At Jensen, to be fair to you and to
the competition, we rate our amps in the two most popular ratings, including
the CEA RMS rating. So feel confident that your Jensen purchase decision
was a sound one, and remember «If it’s Too Loud, You’re Too Old.»
Before You Begin
We need to get the legal stuff out of the way, so please keep reading.
Afterwards, you’ll be armed with the knowledge to install your new hard-hitting,
speaker-pumping Jensen amplifier.
Exposure to loud sounds or music can permanently damage your hearing.
Unfortunately , in many cases, the da mage is not noticeabl e until years later. In
addition, loud music may hinder your ability to hear traffic, police, and fire or
emergency vehicles. Please be responsible and have respect for other peo ple
by listening at moderate volumes!
Warranty Service
If your Jensen amplifier should ever require service, you will need the original
dated receipt. If you must return the unit for any reason, always include the
receipt with the product.

Installation
Before you begin the installation of your Power series amp remember, there
are two ways to do things – right and twice! Use the proper installation
techniques, tools and accessories to ensure that your Jensen Power series
amp will put out all the power it was designed to. If necessary, seek a
professional installer to have the amplifier installed correctly. Most mobile amp
installations do not have the proper g auge wire for power and ground – do not
let your amp be a victim of this common installation oversight!
NOTE: This device is a high-power audio amplifier intended for
installation in vehicles with a 12-Volt negative ground electr ical system.
Attempting to connect or operate the amplifier with another type of
electrical system may cause damage to the amplifier or the electrical
system.
Installation Assistance
For installation assistance, call 1-800-323-4815 during normal business hours,
or visit www.jensen.com at any time.
Supplies and Tools Needed
To install the amplifier, you will need tools, supplies and adapters. It is best to
make sure you have everything you need before you start.
Supplies
• Black electrical tape
• Amplifier Installation Kit
Tools
• Cordless drill with assortment of bits
• Flat-head and Philips screwdrivers
• Wire cutters/strippers
• Crimping tool
• 12-volt test light or digital multimeter
• Wire brush, sandpaper or scraping tool (ground connection to vehicle should
be a clean, unpainted metal surface)
Disconnect Battery
Disconnect the negative (-) battery cable before starting the installation. Check
the battery ground (there should be two (2) ground wires coming from the
battery – one going to the starter mounting bolt or engine block and another
going to the vehicle chassis) and make sure the battery is grounded to the
chassis with at least a #8 gauge wire. Also check the alternator connections,
making sure they are tight and free from corrosion, rust or dirt.
Location and Mounting
The amplifier’s compact design allows great flexibility in mounting. Common
mounting locations include under the front passenger seat or in the trunk area.
When selecting a location, remember that amplifiers generate heat. Select a
location on a flat surface away from heat and moisture where air can circulate
around the amplifier.
Place the amplifier in the mounting location and mark the positions of the holes
with a marker, pen or pencil. Carefully drill the mounting holes in the marked
positions, then use the supplied mounting screws to securely fasten the
amplifier to the mounting surface.
WARNING: Do not cover the amplifier with carpets or enclose it behind
interior trim panels, and do not mount the amplifier in an inverted or
upside down configuration. Be sure the mounting location and the
drilling of pilot holes will not damage any wires, control cables, fuel
lines, fuel tanks, hydraulic lines or other vehicle systems or components.
Routing Wires
Proper wiring connections are illustrated on the following pages. If wiring
connections are made incorrectly, the unit will not operate properly and could
become permanently damaged. Follow the installation instructions carefu lly, or
have the amplifier installed by an experienced technician.

In some cases, the installation of just one (1) amplifier could be enough to
overload your factory electrical system (i.e., alternator). Depending on the
state of your electrical system and overall condition of your vehicle, you may
need to upgrade your alternator and battery. After the vehicle is started, the
alternator provides the power to your electrical system, not the battery. When
the engine is running, the alternator is your main source of power. Upgrading
the alternator should be your first consideration if you should experience a
voltage drop in the system when operating your audio system. Adding
capacitors and/or batteries without upgrading the alternator will only make the
problem worse because these devices put an extra load on the alternator. After
upgrading the alternator , capacitors and/or ba tteries can be installed if desire d.
Use the following recommended wire gauge as a guide when installing your
amplifier(s):
Power Terminal (+12V/B+)
Connect the main power wire to the battery, within 18 inches from the positive
(+) battery post, using an adequate size fuse or circuit breaker capable of
handling the current of the selected power wire. A fuse or circuit breaker must
be installed to prevent a possible electrical fire should the main power wire
short to ground.
Remote Terminal (REM)
Connect the power antenna or amplifier turn-on lead from the receiver to the
amplifier remote terminal.

Ground Terminal (GND)
Make the ground lead as short as possible, leaving enough length to complete
the installation and to allow for any service that may be need ed at a la ter date.
To ensure a good ground, scrape away any paint or undercoating to expose
bare metal. Use a «ring» terminal of the proper gauge and an «outside star
washer» (between the chassis and ring terminal) when making your ground
connection. Although you’ve scraped away the paint to expose bare metal, the
outside star washer will help to «bite into» the chassis for a tight, secure
ground.

Speaker Wiring
The Speaker Wiring diagrams illustrate options for connecting one or two
speakers. Observe the proper speaker polarity.
NOTE: Power amplifiers can drive speakers with a nominal impedance
range of 2~ 4-ohms. For maximum power, configure your speakers for a
nominal 2-ohm load.
NOTE: Do not overlook the use of the proper gauge speaker wire. The
Power series of amplifiers require a minimum of 12-gauge wire.

Input Wiring
Most trunk/hatchback installations will require a 15-20 foot RCA cable, while
pickup trucks and under-seat mounting will require a 6-12 foot RCA cable.
Connect an RCA cable from your receiver to the RCA input on your amplifier.
Power 400/880
Power 900/1050
Power 760/920
The Power 760 and 920 can be configured for three different input modes: 2
channel, 3 channel or 4 channel.

Indicators and Controls
Power Indicator (POWER)
The power indicator provides a visual indication that the amplifier is turned on.
Input Level Control (LEVEL)
The input LEVEL control matches the output of your radio to the input of the
amplifier. After the inst allation is complete, make sure the input level control on
the amplifier is turned down all the way (counter-clockwise or all the way to the
left). Play a tape or CD (make sure bass and treble settings or Bass EQ are
flat) and turn the volume up slowly until you just start to hear distortion. Back
the volume down just a bit. On the amplifier, slowly turn up the input level
control (clockwise or to the right) until you just start to hear distortion, then
back it down a bit. Now your radio and amplifier levels are matched.
BASS EQ
The Bass EQ is continuously adjustable from 0 to +12dB @ 45Hz. Adjusting
the Bass Boost level allows different subwoofer/enclosure combinations to be
equalized. Use this control to increase the level of low bass available from your
subwoofer/enclosure combination. Ported and Band Pass enclosures should
be limited to about +6dB to +9dB of boost. Sealed enclosures should be able
to accept the full +12dB of boost, if necessary. The fu ll +12dB of boost should
be reserved for special applications since improper use of the Bass Boost
could damage your subwoofers at high volumes.
Low Pass Filter (LPF)
The Low Pass Filter controls adjust the crossover point. Typical crossover is
between 60Hz and 80Hz for ported and sealed enclosures. Bandpass boxes
will typically use a higher crossover setting between 125Hz and 150Hz. Since
musical tastes vary, you should play music that you would normally listen to in
your vehicle, with the above settings as a starting point. If necessary, set the
crossover by ear.
High Pass Filter (HPF)
The high pass filter will limit the low frequencies being transmitted to your
speakers. This can be useful in number of situations. For example, if you
selected the high pass filter and set the crossover to 40Hz, then you would
have an infra-sonic (sub-sonic) filter at 40Hz, which would be useful with
certain enclosure/subwoofer combinations that were tuned between 45Hz an d
50Hz. Other uses might include limiting the low frequencies to smaller
speakers (6 1/2″, 6 X 9″, etc.) by adjusting the crossover to a higher setting
(80–100Hz).
Crossover (X-OVER)
The Jensen Power series of amplifiers have built-in low-pass and high-pass
crossover filters for bi-amplifying the system. Adjust the crossover to
accommodate your chosen installation method. Select LPF (low pass filter)
when the amplifier will be driving woofers or subwoofers. Choose FULL when
crossover mode is not active and the amplifier is in “full range” mode. Select
HPF (high pass filter) when the amplifier will be driving full-range or separate
speakers, and you want to limit the “bass” being transferred to these speakers.
Mode Switch
Power 400 and 880
The 400 and 880 come equiped with a MONO/STEREO MODE switch. Use
STEREO mode when you have a 2-channel input from the source unit. Use
MONO mode when you have a single input from the source unit. See “Input
Wiring” on page 8.
Power 760 and 920
The 760 and 920 come equiped with a 2/3/4 MODE switch and can be
configured for three different input modes: 2 channel, 3 channel or 4 channel.

Testing
Before finishing the installation, perform the following tests to make sure the
wiring is correct and everything is operating properly.
Reconnect Battery
When wiring is complete, reconnect the battery negative terminal.
Test Power Wiring
Turn on the receiver, but do not turn up the volume. The amplifier powe r light
should come on. If not, check the REM and +12V (B+) wires. Turn up the
receiver volume slightly. All speakers should operate. If not, check wiring
connections at amplifier and speakers.
Test Speaker Connections
These tests make sure the speakers are connected proper ly. If speakers don’t
play at all, one (or both) speaker wires may be disconnected.
Remote Input Level Control
The Power 900 and 1050 come equipped with a Remote Input Level Control.
The Remote Input Level Control allows the input level to be adjusted from an
alternate location. It can be mounted under-dash or in-dash. When the
amplifier is used to drive subwoofers and the low pass crossover is activated,
the Remote Input Level Control can be used as a “remote bass level control”.
This enables you to control the bass level independent from the rest of the
system. This is convenient for system tuning and/or when playing many
different types of music.
The Remote Input Level Control uses a 6-pin modular cable for connectivity.
Simply plug the 6-pin modular cable into the amplifier and then into the
Remote Input Level Control to activate the circuit.
