Please note: The tone controls have an effect
on the signal level. If the clip indicator flashes
more frequently, reduce the level a bit using
the gain control (see also 4.2)
5.2 Effects
Internal Effects
The Compact 60/4 has a built-in (internal) digital
effect processor. With the select switch you can
choose between 4 different effects.
1 = reverb 1 (short)
2 = reverb 2 (long)
3 = delay (320 ms)
4 = chorus
In the Tommy Emmanuel signature model,
effect #3 is a delay with 213.5 beats-per-minu-
te (this corresponds to 281 ms delay time).
The effects-level control determines the intensi-
ty of the effect (fully anticlockwise = no effect).
In addition, the effect is assigned to one or both
channels by the effects pan control (see below).
External Effects
Furthermore an additional effect unit (external
effect) may be connected to the amplifier. For
this purpose use the send and return sockets
on the rear side of the amplifier (send goes to
the input, return comes from the output of the
external device).
The intensity of the effect is determined by the
external effects unit.
The external effect loop works in parallel mode.
A parallel loop is intended to add the effect
component (for example, reverb) to the original
signal.
pan
Using the effects pan control you can blend
both effects continuously into the amplifier‘s
channels:
Left stop:
internal effect on channel 1
external effect on channel 2
Center pos.:
internal effect on channel 1 + 2
external effects on channel 1 + 2
Right stop:
internal effect on channel 2
external effect on channel 1
Avoid distorted effects
Clipping in the internal or external effect unit
may not be indicated by the clip light. If distor-
tion is audible in in the effect, 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-/off-switch)
can be plugged into the
footswitch
-socket on
the rear side of the amplifier via stereo cable. By
this footswitch the internal and external effects
can be switched on and off.
Suitable footswitches are on-off toggle switches,
which are turned on by stepping once, and
turned off by stepping once again.
5.4 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 amplifier 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 qualified personnel may carry out the de-/
activation of the phantom power.
