5.4 Mute Function
A standard mono-footswitch (on-/off-switch) can be
connected to the
mute foot-switch
-socket on the
top side of the amplifier. By this footswitch the amp
can be muted (headphones, tuner and effect send
are not effected). The footswitch sets the mute
push button out of function.
5.5 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 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.
9 V phantom power at line input
The 9 V phantom power supplies instrument
preamps with power (instead of a battery) that are
prepared accordingly. Such preamps are connected
to input 1 by a stereo jack cable.
The phantom power can be switched on by the 9 V
switch. The yellow indicator lamp then lights up.
Sources that don't need phantom power should
always be connected via a mono jack cable (not ste-
reo) as a precaution. This way the phantom power
cannot get to the source and possibly damage it.
Also make sure that the plugs are fully plugged in.
Notes on the use of phantom power
Phantom power means remote power supply of an
audio device (e.g. microphone) via the audio line.
Only suitable devices should be connected to an
input with (activated) phantom power.
Such devices are also marked accordingly. Please
heed the permissible power consumption (see
technical data).
Some devices do not need phantom power
but tolerate it.
Other devices that have not been designed expli-
citly for phantom power operation can suffer from
considerable malfunction and damage may result
as well.
In case of uncertainty please consult the
manufacturer of your accessories.
5.2 Effects
Internal Effects
The
MM
200 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
The effects-level control determines the intensity
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 compo-
nent (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 distortion is audi-
ble in in the effect, reduce the gain controls until the
distortion disappears. Subsequently 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.
We wish you lots of fun playing your
MM
200!
