Volume knob (30) setting. Use knob 59 to dial in the relative volume to
High Gain mode.
60 Pre Out
This is the INVADER's preamp auxiliary out. It delivers a signal with almost the same
level and frequency response as the signal patched into the amp's input. A low-
impedance circuit,
Pre Out signal is patched out to jack 60 even when
serve as an effect device send, whereby the amp's preamp (EQ and gain stages) is
bypassed.
61 Line Out
This jack taps into the power amp circuit to retrieve its signal. The frequency response
of the Line Out's and the Power Amp Output's signals are identical (Line Out is not
frequency-compensated). Use it to do things like drive another linear power amp or
frequency compensation filter, say to simulate a 4/12 cabinet and feed this signal to a
recording system or PA.

IMPORTANT NOTE, please read and heed: Never operate the power amp without a
sufficient load, otherwise you may damage or destroy it!
An electronic surveillance system constantly monitors if a plug is inserted into the
speaker outputs
inserted into one of these 5 jacks, the power amp is disabled and the Status LED flashes
in a distinctive pattern to alert you to this. However, the system cannot check if a
speaker is actually connected to the other end of the cord. That's your job.
Always check and verify that the amp's output impedance matches the connected
cabinets' impedance!
Cabinet options
1. One 4-ohm cabinet connected to a 4-ohm jack;
Summary: 4 Z, -> connected to 4-ohm output.
2. Two 8-ohm cabinets connected to the 4-ohm jacks;
Summary: 8 Z + 8 Z, -> connected to 4-ohm + 4-ohm output.
3. One 8-ohm cabinet connected to an 8-ohm jack;
Summary: 8 Z, -> connected to 8-ohm output.
