In addition to a first class tube tone, the          poweramp offers a number 
of practical features in a powerful 2x60 watt (Model 930/120=>2x120 W) 
package. A switchable input system (INPUT A/B) enables you to switch back 
and forth between two preamps; each of the two stereo channels features 
two volume and two presence controls (A and B), so you can dial in diverse 
volume and presence settings for each preamp. The A/B controls, in 
combination with one preamp, also enables you to activate different volume 
and presence settings for an incredible range of switching options. The 
DEPTH BOOST button delivers loads of low end. Similar to the A/B functions, 
it is also switchable via an external footswitch or MIDI commands via the 
       

 MIDI Interface

. The GAIN button provides optimum input signal levels 

for both poweramp sides and the MONO/STEREO function enables you to 
activate the mono mode where both poweramp channels receive identical 
signals. You can assign the INPUT A/B button´s function to the A/B 
VOLUME switching via a button located on the rear panel.            
Comprehensive connection options offer you maximum flexibility: the Stereo 
Master FX Loop enables you to patch in FX devices in combination with two 
preamps. The 930 is equipped with 4, 8 and 16  ohm speaker outputs for 
virtually any kind of cabinet rig you care to devise. Separate Standby 
switches provide a single p.a. side operation option. 
The integrated 

E.C.S. (Emergency Circuit System)

 protects the amp from 

damage due to power tube defects/failure and ensures the amp does not 
shut down. It continues to function on both channels; the affected channel 
operates at a reduced power output level.
This amp is defined by the effort and materials that went into it:
intelligent design features, superior craftsmanship, impeccable finishing and 
quality components. However keep in mind, that a few precautions will 
radically extend tube life 

(see handling and care guidness)
