Phono/RCA (unbalanced); Tip=Signal Positive, Sleeve=Signal Ground.
XLR (balanced); Pin1=Signal Ground, Pin2=Signal Positive, Pin3=Signal Negative.

Speakon; 1+=Speaker Positive. 1-=Speaker Negative.
Binding Posts; Red=Speaker Positive. Black= Speaker Negative.
1)
IEC Mains Inlet – Use only the supplied power cord or suitable replacement with the
correct fuse. The IEC inlet also features an integral Mains Fuse – Replace only with the
same rating as originally supplied. If the fuse fails do not replace with a higher value.
2)
Channel B speaker output via SPEAKON socket. Use 1+1- terminals only, minimum
speaker impedance 4Ω
3)
Channel A speaker output via SPEAKON socket. Use 1+1- terminals only, minimum
speaker impedance 4Ω
4)
Ground Lift Switch – some equipment may present a mains hum/buzz, this switch will
remove the signal ground and reduce the effect of the mains hum.
5)
Balanced 6.35mm (1/4”) Jack for signal level (0.775mV) input. This input may also be
used for unbalanced signals.
6)
Balanced XLR for signal level (0.775mV) input
7)
Channel B speaker output via Binding Posts. Minimum speaker impedance 4Ω. As with
all speaker wiring care must be taken to ensure no wires can present a short cirtcuit to
the amplifier. Speaker wires carry high voltages, care should be taken to ensure
no bare wires can be touched as this may result in electric shock.
