Send Socket (7 Band); Return Socket (7 Band); Loop Switch (12 Band); Mute Switch - TRACE ELLIOT AH1200-12 Owner's Manual

Compression applied to the high band will directly effect the attack portion of the note and should be used
carefully. However, even extreme settings can produce some interesting effects for both slapping and fretless
techniques and will help to make harmonics jump out in the mix.
If the VALVE drive circuit is being used at high settings then the high band compressor can be used to control
and smooth out the overdrive produced resulting in quite a processed, produced sound.
Experimentation with many different settings of the compressor will help to get the most out of it.
Please be aware that due to the nature of any compression circuit that then adds make-up gain to bring the
nominal level up, dialling in high levels of compression will increase high frequency hiss between notes.
This is not added by the compressor circuit, but is hiss that is already present in the signal and is then being
amplified. However, as this is only really noticeable when not actually playing, if high levels of compression
are desired it is possible to prevent the noise from being heard too much by using the footcontroller to turn off
the compression or mute the signal when nothing is being played.

(17) SEND socket (7 Band)

This is a 1/4" jack socket for connecting to the input of effects units.

(18) RETURN socket (7 Band)

This is a 1/4" jack socket for connecting to the output of effects units.
The effects loop on the 7 Band range is an easy to use, unity gain, series effects loop. The user can simply
connect effects units between the SEND and RETURN sockets and the effect will be applied to the whole signal.
The normal bypass on each effect unit can still be used to turn the effect on and off during a performance.
The nominal level has been set to -10dBV to be able to drive most commonly used effects units. If the
effects units have their own level controls, please ensure these are set correctly to prevent distortion occurring
anywhere in the overall system.

(19) LOOP switch (12 Band)

Pressing the switch adds the EFFECTS LOOPS in to the signal chain. Its status is shown by the orange LED
and it can also be controlled by the footcontroller.
All the connections for EFFECTS LOOPS are on the rear panel. See below for a full description.

(20) MUTE switch

Pressing this switch will mute all outputs, (speaker, line and DI) except for the TUNER output. Its status is
shown by the red LED above the OUTPUT LEVEL control which will flash when MUTE is selected. It can
also be operated using the footcontroller.
The MUTE function is useful for preventing unwanted noise between songs, when changing instruments or, if
a tuner is connected to the TUNER output, for tuning up silently without needing to make adjustments to any
other controls. The signal level indicators remain active when in mute so it is possible to change basses and
set up the INPUT LEVEL silently without turning the OUTPUT LEVEL to zero and therefore risk forgetting
the setting.

(21) OUTPUT LEVEL rotary control

This sets the signal level sent to the power output stage and the LINE OUT(s). It should be set at "0" when
switching on the amplifier and turned up to the desired playing volume slowly to avoid any sudden level
changes that could damage your hearing.
