Power Supply, On/Off Switching

Be sure before connecting the Volume 2 to power that the rear-chassis 
voltage supply is switched to the proper local rating (either 230 or 115 volts).

Above all, before connecting any machines, always take additional care to 
power down all those to be used (and move the rear-chassis power supply 
switch of the Volume 2 to the “down“ position).

Finally, always use the following procedure in powering up your assembly:

Always power on your Volume 2 fi rst before the power amp or active 
speakers. When powering down, always power off the power amp or active 
speakers before your Volume 2. Not following this sequence can result in ear 
or speaker damage from high level discharges!

The Volume 2 comes with a standardized 3-pole (grounded) IEC power cord 
which is connected to the main power input socket (Mains Input). The trans-
former, cable and socket conform to VDE, UL, and CSA requirements. The 
actual power ratings are 250mA at 230 volts and 500mA at 115 volts.

Balanced right and left XLR Inputs 

to provide for stereo source connections.  

The nominal signal level is at +4 dB, other levels will be transmitted 1:1.

Balanced right and left XLR Outputs 

to provide for connections to power 

amps or active speakers.
