level. The level is adjusted by the front controls (12) and (13).
• LINE 3-4: Use these unbalanced RCA jacks to connect units with line level (e.g. CD players). The level is
adjusted by the front controls (15) and (16).
• LINE OUT: This unbalanced RCA output provides the mixed signal to connect, e.g. an additional amplifier
Cable connections
The amplifier offers numerous, highly flexible possibilities for balanced or unbalanced connection of
professional audio equipment. To avoid interfering noise, switch off the device or set the output controls to
minimum prior to connecting and disconnecting equipment. Be sure to use only high-grade cables. The
illustrations below show the wiring of these cables.
