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.

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.
