Digital Effects (Ch 1); Channel 2; Gain Control (Ch 2); Tone Controls (Ch 2) - YORKVILLE Traynor Acoustic Master Standard Mode D'emploi

6. Digital Effects (Ch 1)

From lush reverb to a swirling rotary speaker simulator, the Acoustic Master Standard 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. See the end of the
manual for a description of each effect.
An optional footswitch can be used to bypass the Acoustic Master Standard's built in effects. Use a two-channel
footswitch such as the Apex AFS2 to allow you to bypass channel 1 and 2 independently.

7. Channel 2

This channel accepts line level signals from active acoustic guitars or other line level sources via 1/4-inch
cables. It also takes microphones through balanced XLR. Controls include Gain, Bass and treble equaliza-
tion. 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 1/4-inch portion of Channel 2.

8. Gain Control (Ch 2)

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.

9. Tone Controls (Ch 2)

Channel 2 has a two band EQ for controlling your sound. Use the Bass and Treble controls to boost or cut your
signal to meet your needs.

10. Digital Effects (Ch 2)

Channel 2 has its own dedicated bank of 16 custom Traynor effects. Just as on Channel 1, the Mix control blends
between your dry and wet signals while the Modify control alters the nature of the selected effect.

11. Master Volume

The master control is used to increase or decrease the overall output of the Acoustic Master Standard. It has no ef-
fect on the line out signal level or the effects loop.

12. Effects Loop

Your Acoustic Master Standard has been equipped with an effects loop to allow you to add off-board effects to your sig-
nal. The effects loop occurs just before the Master Volume but after Channel 1 and 2 signals have been combined.
Connect a stereo 1/4-inch cable from the EFX Send jack on the back of the Acoustic Master Standard to the input of
your effects unit. The 1/4-inch cable carries stereo right on the ring, stereo left on the tip and ground on the sleeve.
Connect the output of your effects unit to the EFX Return jack located on the rear of the Acoustic Master
Standard. The signal will go directly into the amp just before the Master control. Using the same convention as
the EFX Send jack, a stereo signal can be passed on a stereo 1/4-inch cable. You can also supply the amp with
a mono signal. Use the Stereo/Mono switch next to the Effects Loop to select what type of signal you are using.

13. Aux In

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.

14. Footswitch Jack

An optional footswitch such as the dual switch, latching APEX AFS2 can be used to bypass the built in effects for
either channel, independently of each other.
15. Line Out - Post Effects (1/4-inch jacks, L&R)
The stereo line out jacks are located at the back of the unit and are post effect signals. They are low noise, balanced
TRS lines which can be used to connect to recording devices, mixers or other amplifiers. The Master Volume control
does not affect the signal however the Volume and Tone controls of Channels 1 and 2 do.
