AER Compact 60/4 - Functional Characteristics; Tone Control Features; Internal and External Effects; Footswitch Operation

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
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.
