(21) PRECISION BALANCED DIRECT INTERFACE
This XLR output is used to connect the Max pre amp section to external equipment, such as mixing consoles, external power amplifiers,
or recording equipment. This novel circuit provides a perfectly balanced and noise-free signal with none of the problems associated
with small transformers.
(22) DI GND LIFT SWITCH
This switch may be used to eliminate hum caused by ground loops between the amplifier and other equipment, such as a mixing con-
sole.
(23) FX LOOP
The effects loop consists of the SEND and RETURN jacks, which are used to patch external effects processors post EQ in the signal
chain. Connect the SEND jack to the input of effects processors. Connect the RETURN jack to the output of effects processors. The EF-
FECTS SEND and RETURN jacks can also be used as a line level unbalanced preamp output and power amp input jacks, respectively.
