E Ects; Footswitch; Phantom Powering - AER Compact 604 Mode D'emploi

Please note: The tone controls have an e ect
on the signal level. If the clip indicator ashes
more frequently, reduce the level a bit using
the gain control (see also 4.2)

5.2 E ects

Internal E ects
The Compact 60/4 has a built-in (internal) digital
e ect processor. With the select switch you can
choose between 4 di erent e ects.
1 = reverb 1 (short)
2 = reverb 2 (long)
3 = delay (320 ms)
4 = chorus
In the Tommy Emmanuel signature model,
e ect #3 is a delay with 213.5 beats-per-minu-
te (this corresponds to 281 ms delay time).
The e ects-level control determines the intensi-
ty of the e ect (fully anticlockwise = no e ect).
In addition, the e ect is assigned to one or both
channels by the e ects pan control (see below).
External E ects
Furthermore an additional e ect unit (external
e ect) may be connected to the ampli er. For
this purpose use the send and return sockets
on the rear side of the ampli er (send goes to
the input, return comes from the output of the
external device).
The intensity of the e ect is determined by the
external e ects unit.
The external e ect loop works in parallel mode.
A parallel loop is intended to add the e ect
component (for example, reverb) to the original
signal.
pan
Using the e ects pan control you can blend
both e ects continuously into the ampli er's
channels:
Left stop:
internal e ect on channel 1
external e ect on channel 2
16
Center pos.:
internal e ect on channel 1 + 2
external e ects on channel 1 + 2
Right stop:
internal e ect on channel 2
external e ect on channel 1
Avoid distorted e ects
Clipping in the internal or external e ect unit
may not be indicated by the clip light. If distor-
tion is audible in in the e ect, reduce the gain
controls until the distortion disappears. Subse-
quently you can restore the previous volume
with the master control.

5.3 Footswitch

A standard double-footswitch (on-/o -switch)
can be plugged into the footswitch-socket on
the rear side of the ampli er via stereo cable. By
this footswitch the internal and external e ects
can be switched on and o .
Suitable footswitches are on-o toggle switches,
which are turned on by stepping once, and
turned o by stepping once again.
5. Phantom power
48 V phantom power at microphone input
Microphones that require 48 V phantom power
(P 48) can be connected directly to mic in by
an XLR plug. The ampli er is supplied with 48 V
phantom power enabled, but it can be disabled
by an internal jumper (see note).
When connected by a jack plug, the 48 V
phantom power is not applied. Use the jack
connection for microphones that must not be
connected to phantom power.
Please also read the general notes on
phantom power.
Please note: For the alteration mentioned
above, the device must be opened, therefore
only quali ed personnel may carry out the de-/
activation of the phantom power.
