REAR PANEL FUNCTIONS

1. EFFECTS LOOP LEVEL
Set the loop level to match the type of effect(s)
connected to the effects loop, from -10dBV to
+4dBu. Higher levels suit rack processors and
lower levels suit floor pedals.
2. EFFECTS LOOP SEND
Sends signal to effects loop/outboard
equipment.
3. EFFECTS LOOP RETURN
Returns signal from effects loop/outboard
equipment.
4. RECORDING COMPENSATED LINE OUT

recording equipment or a PA system. The signal
is specially filtered for optimum recording
performance.
5. DIRECT LINE OUT

external power amp.

Note: using the direct line out does not omit
the need for a speaker load.
6. OUTPUT IMPEDANCE SELECT
Use this switch to match the impedance of
the amp to the resulting load of the speaker
cabinet(s). Ensure the amp is completely powered
down before using the switch.
Common setups include:
• To use the outputs with one 16Ω cabinet,
set the switch to '(4)16'.
• To use the outputs with an 8Ω load (by using
either one 8Ω cabinet or two 16Ω cabinets)
set the switch to '8'.
This amp should not be used with a load rated
at less than 8Ω.
Warning: failure to comply with these points
may damage the amp.
7 & 8. SPEAKER OUTPUTS
Connect one or two speaker cabs here using
1/4" jack speaker cables.
