Welcome to Acoustic Image!
You have purchased a state-of-the-art musical instrument amplifier system,
combining purity, power and portability in a package that sets a new standard
in high fidelity amplification.
Each of our designs is engineered to accurately reproduce the sound of
acoustic and electric instruments, delivering flat frequency response across
the entire musical spectrum; extended, tight, well-controlled bass; and
complete clarity of sound reproduction.
This manual provides operating information for your Acoustic Image Ten2 and
the Ten2 EX extension speaker cabinet.
The Basics
The Ten2 has a superb class-D power amplifier with switch mode power
supply, a compact two-way speaker system and a sophisticated, sensitive
preamplifier. It also has the exclusive Cabrio Docking System that allow the
head unit to be removed and used as a stand-alone amplifier.
The power amp is a high efficiency, 800W design that requires no external heat
sinks or cooling fans and is capable of driving loads as low as 2 ohms. AC
power and output speaker jacks are located on the rear of the enclosure. A
standard, three-prong detachable AC power cord is used to provide power to
the unit, while an AC voltage selection switch allows the unit to operate at
115V/60 Hz or 230V/50 Hz. Japan models operate at 100V, 50/60 Hz only. See
the rear panel of your amp to verify theAC voltage capability.
The input channels of the preamp incorporate combo jack interfaces that allow
either a high impedance instrument input (to optimize the sound of piezo-type
pickups) or a mic input with a built in 10 dB pad, an effects
loop with return level control, a selectable low cut filter for reduction of low
frequency boominess, a phase reverse switch, a direct out capability with
ground lift and pre/post EQ switch, a master level control and a mute switch.
The preamp also has a switch that allows the second channel to be
disconnected from the main amp and connected to a satellite power amp to
create a stereo system.
The speaker enclosure incorporates a 2x10-inch woofer configuration (one is
downfiring and the other is front firing) and a 2.5-inch tweeter that is coaxially
mounted in front of the front firing woofer. The tweeter has a three position level
control (0 dB, -6 dB and off). The exclusive Room Coupling Control allows the
user to adjust the output of the downfiring woofer to help control boominess in
certain acoustic settings. A built-in, spring-loaded tilt mechanism allows the
cabinet to be tilted back to better direct sound to your listening position. The
cabinet is made of an acoustically inert, high durability, injection molded
polymer material which dramatically reduces the weight of the cabinet. Each
unit comes with a fitted slip cover and shoulder strap. A padded case is
available.
a three-band EQ,
The Ten2 is the loudest combo amp that we make but in designing it, we chose
fidelity over efficiency so it won’t play as loudly as the typical, lower fidelity 2x10
system. To generate higher SPLs may require an extension cabinet like the
Ten2 EX or augmentation by a larger house system.

Power
Plug the detachable AC power cord into the receptacle on the back of the amp
and into a wall receptacle. A power switch next to the AC connector turns on
power to the pre- and power amps, illuminating a “power on” indicator on the
front panel of the amp. An 8-amp fast blow fuse is mounted on the back panel.
To replace the fuse, turn off the amp, remove the AC cord and use a small
screwdriver to remove the fuse from the fuse holder. A spare fuse is included
with this manual. The Ten2 will work with either 115 volt, 60 Hz AC or 230 volt,
50 Hz AC power. A switch located on the rear panel selects the appropriate
voltage. Note that the correct AC power cord must be used for connection to
the appropriate wall plug. If you do not have the right cord, you can buy one
from an electronics or computer store. Be sure the switch is in the correct
position for the intended application.
Please note that units sold in Japan operate at 100 volts only. The above
mentioned voltage switch is not available for these units.
The Ten2 uses combo jacks for the input to each channel of its preamp. Either
an XLR or 1/4 inch connector can be plugged into this type of jack. The 1/4 inch
input has a 1 megohm input impedance that is optimized to get the best sound
from piezo pickups. The XLR input is a low impedance balanced input with
sufficient gain to allow microphones to be plugged into it. A switchable 10 dB
pad is provided to attenuate the output of microphones that are too “hot” for the
mic input. Phantom power is available through the connector for powering a
mic or outboard preamp and can be

when phantom power is on. The two channels of the combo can blended
to mix two instruments, 2 microphones or a mic and an instrument thereby
performing much like a small PA system.

Controls
The preamp has the following controls in each channel: input level, bass, mid,
treble and effects level. In addition, there is a variable frequency, selectable
low cut filter and a phase reverse switch in each channel and a master level
control that affects both channels.
The input level controls the level of the signal at the input stage of the preamp.
The master volume controls the level of the signal at the output of the preamp
(at the input of the power amp). Set the master control at “12 o’clock” and the
input level at zero. The input level should then be used to control the overall
output of the unit. The two controls are provided to allow independent control of
“house” volume and “stage” volume when the unit is used as a stage monitor
with a connection to a house PA. See the discussion under “Direct Out” below.
The maximum volume at which the system will play is limited by the capability
of the speaker system. If more volume is needed, use a Ten2 EX extension
cabinet or take a feed from the Direct Out jack to a PA system or another
amplifier.
Each tone control has a center detent at the flat position. Experiment with
settings to achieve the frequency balance that sounds best to you. In general,
small values of boost and cut are best. The amp is designed with flat frequency
response so only minor corrections should be required to compensate for room
effects or “peaky” pickups in order to maintain the balanced response desired
for acoustic instrument amplification. To minimize electronic noise, avoid
operating all controls simultaneously at their maximum settings.
The bass control is a shelving-type that affects frequencies below 250 Hz and
with a maximum boost/cut of 15 dB. The mid control affects frequencies
between 300 Hz and 2000 Hz and has a maximum boost/cut of 15 dB. The
treble control is also a shelving-type that affects frequencies above 1000 Hz
with a maximum boost/cut of 15 dB.
The low cut filter is a variable frequency type that inserts a 12 dB per octave
rolloff at frequencies between 30 and 400 Hz, depending on the position of the
control. Approximate frequency settings are noted on the frequency control.
Note that the first half of the control’s rotation affects frequencies from 30 to 60
Hz, the last half of the rotation affects frequencies between 70 and 400 Hz. This
is done so that there is plenty of control in the critical low frequency range.
Level
Tone
Low Cut Filter/Phase Reverse
The
low cut filter is used to reduce the bass output in cases where room location or
instrument/pickup combination results in “boomy” sound. Depress the on/off switch
to enable the filter. Start with the control fully counterclockwise and gradually turn it
clockwise until the desired effect is achieved. Experiment with the position of the
control to give you the sound you like best.
The phase reverse switch is used to reduce feedback and to control interactions
between the two channels. If you are using two pickups or a mic and a pickup, you

4
will find the phase reverse switch to come in handy. Feedback resulting from the use
of a mic can be reduced by inverting the phase in the channel in which the mic is
input. Phase related interactions between a pickup and a mic or two pickups can be
cleared up by reversing the phase of one of the channels and not the other. You
should experiment with the phase reversal switch in each channel to see if the effect
is one that you like.
Effects Loop
Direct Out
Mute Switch
If you are not getting any sound out of the amp, check to
make sure that the mute switch is off.
Acoustic Image preamps have output (“Send”) and input (“Return”) capability
in each channel to allow you to use effects boxes. The send output is affected
by the input volume and tone controls and can also be used as a preamp output
for driving other power amplifiers. The Return input can be used to directly
connect an external preamp to the unit’s power amp. The effects level control in
each channel controls the volume of the returned (“wet”) signal relative to the
original (“dry”) signal. Because the effects loop is a parallel type, plugging
something into the send output does not interrupt the signal path. So, a tuner
can be plugged into the send output without affecting the signal going through
the amp. When the effects loops are not used, the level controls should be set
at zero.
The return input can also be used as an auxiliary input for connecting other line
level signals such as a CD player.
An XLR jack is provided for a Direct Out connection that allows the system’s
output to be fed to mixing boards of house PA systems or recording studios. As
a result, the instrument amplified by the unit can be recorded or further
amplified by the house PA system. In the Ten2 combo, the Direct Out signal is
the combined output of the two channels. A switch is provided to allow you to
select whether the output from the Direct Out jack is affected by the tone
controls (post EQ) or not (pre EQ).
With the switch in either the pre or post EQ position, the input level control
affects the level of the Direct Out signal, the master level does not. This allows
independent adjustment of the “stage” volume (the volume coming from the
combo amp) and the “house” volume (the volume in the house PA system)
when the unit is used as a stage monitor. Once the level has been set for the
house, if more volume is needed on stage, the master level can be increased.
This will increase the stage volume but not the volume in the house PA.
A ground lift switch is available to “lift” the ground from the output of the direct
out--reducing noise should a ground loop create hum when the unit is
connected to a mixing board.
A switch is provided to allow you to mute the output of the amplifier without
having to turn the amp off. This will allow you to tune your instrument on stage
without being heard. The amp output and direct out signals are both muted by
the switch. The mute switch has a red button on it to remind you that it is an
important switch.

output. By connecting the send output to a satellite power amplifier, and putting
the switch in the off position, the preamp operates in stereo mode. Note that
channel 2 remains in the direct out signal even when the switch is in the off
position. This is done since stereo operation is typically a “stage” mode but not
a “house” mode (house systems are typically not stereo). The Ch 2 switch has
a red button to remind you that is is an important switch.
Our high-quality effects unit offers 6 program selections: 3 reverb programs
(Hall, Room and Plate), a delay, an ambient chorus and a flanger. There are
switches to select which of the two channels are processed by the effects unit.
Either channel can be connected to the effects unit. If both switches are
engaged, the selected program appears in both channels. A level control
affects the level of the effects signal that is mixed with the “dry” signal to control
the overall effect of the selected program. You should experiment with both the
program selection and the level control to find the sound that you prefer. When
effects are not used, the switches for both channels should be off and the level
control should be turned fully counterclockwise. Note that the flange effect is
noisy, it is normal the hear the modulation of the flanger when no signal is
present.
There is a headphone output on the rear panel of theTen2. You can plug a
standard 1/4 inch stereo plug into this output to connect a headphone for
private listening. If your headphone has a 1/8th inch plug, you can buy an
adapter to allow you to use the 1/4 inch output jack.
When you plug into the jack, the amp is muted. Sound will only be heard
through the headphones. The headphone is connected to the output of the
preamp so all of the controls on the preamp, including effects, will affect the
signal heard through the headphone. When the headphone plug is removed
from the jack, the amp will come back on.
Anytime anything is plugged into the headphone output jack, the
amp will be muted so make sure that nothing is plugged into the jack when you
want to use the amp normally.
The amp head component of the Ten2 can be removed and used as a stand-
alone amplifier. To remove the head unit, first disconnect the short speaker

Removal Insertion
cable that connects the speaker cabinet to the amp, then unscrew the docking
screws on the rear panel until they are loose. Grip the cabinet as shown and
use the tips of your fingers to push the head unit out. The fit is quite snug so
some force will be needed.
Once you have removed the head, you will notice the rubber feet stored in a
compartment on the bottom. Remove the feet and screw them into the four
positions on the bottom of the head. When you want to put the head back into
the cabinet, you will have to remove the feet and put them back into the storage
compartment.
To reinsert the head unit, grip the cabinet as shown and push it in with your
thumbs. Again, the fit is snug so some force will be needed. Once the head unit
is in place, tighten the docking screws to pull the head tight to the docking plate.
Reconnect the speaker cable and the unit is ready to go. When transporting the
Ten2, it is best to disconnect the speaker cable at the speaker end so that there
is no cable loop that can get caught on passing objects. The cable will have to
be disconnected in this way so that the slip cover will fit over the amp.
An extension speaker (ideally, the Ten2 EX) can be connected to the amp to
increase its output level using the jack provided on your amp’s rear panel.
Speakers are connected via Neutrik Speakon connectors (“twist lock” type).
These connectors are used because of their low contact resistance and non-
shorting operation. The output of each Speakon connector is wired to pole “1”.
Make sure the cables you use to connect an external speaker are similarly
wired.
The Ten2 has two outputs on the rear panel but one of them is used to connect
to the internal speaker via the short jumper cable. So, one output is available
for connecting an extension cabinet.
The power amplifier in the Ten2 is capable of driving speaker loads as low as 2
ohms. Use a high quality speaker system in order to get the maximum
performance from the amp. The Acoustic Image Ten2 EX is an excellent
choice.
The power amp is short circuit protected. If a short is connected to the
extension speaker jack (or if the internal speaker is shorted), the output signal
will be interrupted until the short is removed. If a short is present, you will hear a

ticking sound at 3 to 4 second intervals which indicates that the short circuit
protection is working.
The Ten2 can be operated with the speaker disconnected. This can be useful in
two circumstances. The first is when you are recording from the direct out of the
preamp and don’t want the output of the combo amp to be heard. In that case,
disconnect the internal speakers and set the master level to zero. By setting the
master level to zero, the signal to the power amp is turned off and it is not driven
without a speaker load which can damage the amp.
In some settings, such as a hollow stage or small, “boomy” room, your amp or
enclosure will produce too much bass. One way to cut unwanted bass output
is to use the built in tilt back feature to lift the front of the cabinet, reducing the
coupling to the floor. To do this, pull the stand into its forward position and set
the combo in place on the floor. The stand is spring loaded so when you pick up
the unit, the stand will spring back into its storage position. You may want to use
the tilt stand at all times in order to aim the high frequency output of the speaker
toward your ear so that you can better hear the amp.
The tweeter level control is located on the rear panel of the speaker cabinet
(see picture of the rear panel below). It is a three position switch with a selection
of zero attenuation, 6 dB attenuation or off. The tweeter operates from 3000 Hz
an up so it’s effect on the sound will be audible. Under most circumstances, it
should be operated with zero attenuation. Experiment with the control and pick
the level of attenuation that sounds best to you.
To be on the safe side, you should shut off the power
to the amp before connecting or disconnecting speakers from the unit.
Be sure to set the master
level to zero when you have disconnected the internal speaker and
another speaker load is not connected to the amp. Operating the combo
with no load and the master level turned up can damage the amp.
Tilt Mechanism
Speaker Placement
Tweeter Level Control
The omnidirectional low frequency output of the Ten2 and Ten2 EX makes speaker
placement relatively noncritical. You will easily be heard all over the bandstand no
matter where one or more are located. However, best results are obtained when the
cabinet is placed on the floor. Putting the unit on a shelf or stand will reduce bass
frequencies. There may be circumstances where this is desirable. Again, feel free to
experiment to find the sound that is best for you.

Room Coupling Control
Description of the Ten2 EX
Care
The Room Coupling Control is also located on the rear panel of the speaker
cabinet. It is used to control the low frequency output of the downfiring woofer. It
is useful in controlling “boominess” in difficult acoustic settings. It is a three
position switch with settings of 100%, 75% and 50%. At the 100% setting, the
downfiring woofer is operating at full output. At the 75% setting, it’s output is
reduced slightly. Use this setting when there is only moderate boominess in the
room. At the 50% setting, the output is reduced even more. Use this setting for
the most difficult situations. Experiment with the control so you can get a good
idea of its effect on the sound.
The Ten2 EX is the speaker cabinet portion of the Ten2 combo. It is about 3
inches shorter and about 5 pounds lighter than the Ten2 because the docking
bay for the amplifier is not attached and the amp head is not provided. It has the
same speakers and the same performance as the Ten2. It is the ideal extension
cabinet for the Ten2 but it can also be used effectively with any of our other 1x10
combo amps. In fact, the other combos can be stacked on top of the Ten2 EX to
create a 3x10 system.
Acoustic Image combos and cabinets are made from injection molded polymer
materials. A little care will keep yours looking new for years to come. Use a
clean, dry cloth to clean the cabinet and metal parts of the amplifier.
We stand behind our products with a full warranty of five years from the date of
purchase. Should a problem arise, please call us before returning your
