Master Volume; Aux Input - Traynor Acoustic Master Studio Mode D'emploi

5. Notch Filter Control (C
Use Channel 1's sweepable notch filter to eliminate feedback caused by the guitar being too close
to the amp at higher power. If feedback does occur, rotate the notch control slowly until the feedback
is eliminated. To bypass this filter, rotate it fully counter-clockwise to the off position. Please note that
if feedback occurs when you are in close proximity to the guitar amp, the notch filter may not help.
Therefore either reduce power or move the guitar farther away from the amplifier.
6. Channel 2
This channel accepts line level signals from active acoustic guitars or other line level sources
via ¼-inch cables. It also takes microphones through balanced XLR. Channel 2 has a flat
frequency response, making it ideal for vocals, keyboards, and drum machines. The channel
input is balanced but can also accept unbalanced cables. To reduce noise, it is advised that
you use balanced cables for interconnection wherever possible.
In order to power condenser mics, a 15 volt phantom power is applied to devices connected
with an XLR cable. Using a correctly wired XLR cable, phantom power is effectively invisible
to balanced dynamic mics and will not cause any damage. Phantom power IS NOT applied to
the ¼-inch portion of Channel 2.
7. Gain Control (C
h
The Gain control is used to set the input level of your instrument. The clip LED can be used to
gauge input level to avoid audible clipping. If clipping does occur, lower the signal by turning
the volume down on your guitar or reducing the Gain control.
8. Tone Control (C
h
Channel 2 is also equipped with a tone control for shaping your sound. At the mid
position, your tonal response is flat. Going clockwise will add more treble and rolloff
some bass. Turning the knob counter clockwise with do the opposite, removing top end
and accentuating the bass.
9. Master Effects
From lush reverb to a swirling rotary speaker simulator, the Acoustic Master Studio uses a
DSP (Digital Signal Processor) to create 16 custom Traynor effects. The Mix knob is used to
blend in the required amount of the original, clean signal. The Modify control is used to alter
the chosen effect. The parameter that can be changed is listed for each effect on the plate
found on the top of your amp.
Channel 1 is always linked to the built-in effects. Turn the Mix control fully counter clockwise
to bypass these effects if desired. The Channel 2 can be inserted into the effects chain by
depressing the CH2 EFX button.

10. Master Volume

The master control is used to increase or decrease the overall output of the Acoustic Master
Studio. It has no effect on the line out signal level or the effects loop.
11. Effects Footswitch
An optional footswitch, such as the single-switch APEX AFS1, can be used to bypass the
built in effects.

12. Aux Input

The Aux In consists of a stereo RCA for use with line level devices like MP3 players, CD
players, etc. The signal is injected before the Master Volume control.
13. Line Out
The balanced Line Out jack outputs a signal carrying a summed channel 1 and 2, post-
effects, pre Master Volume. This means the Gain controls do affect the output of the
Balanced Line Out with the effects being audible but the Master Volume control will not
attenuate the signal. The Line Out can be connected directly to a mixer, a recording device
or even another amplifier.
