Send Socket (7 Band); Return Socket (7 Band); Loop Switch (12 Band); Mute Switch - TRACE ELLIOT AH1000-12 Guide D'utilisation

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.
