Other amplifier functions
•
Microphone signals may be recorded at the RECORD outputs, without being influenced by the volume setting.
•
Parallel operation of 2 amplifiers is also possible in the AUTOMATIC Mixing mode. In this case the PARALLEL
connectors of both amps are used for both amplifiers. The input of amplifier 1 with the output of amplifier 2
and vice versa.
•
An external effect device (FX), such as Echo, may be looped into the signal path of the amplifier via the parallel
connectors between INPUT and OUTPUT .
•
The AMV7240 MKII features a LINE OUT, 3 pin balanced xlr connector with a nominal output level of 1.55 V. It
may be used for connection to additional amplifiers, for example induction loop amplifiers. The output signal and
level is predetermined by these jumper settings:
J23 at the rear is the standard setting. Level is dependent from master eq and master volume.
J21 in the center sets the level to be independent from both master eq and master volume.
J22 up front sets the output level to be independent from master eq, but dependent from master volume.
9. Output power
The AMV7240 MKII features a transformer isolated 100 V 240 W constant voltage output. The transformer has two
more constant voltage windings (50 V and 70 V) that are not being used. However, re-soldering by qualified persons
makes this feature available. Secondary winding identifications are: green = 0, White = 100 V. Close to the 100 V
winding output is a 70 v soldering joint and close to the 0 joint the 50 v winding.
