16. LINE OUT
The pre master volume signal, processed
through a 4x12” speaker cabinet emulator
and electronically balanced, is made
available at this connector.
17. POWER AMP INSERT / SERIAL LOOP
This is a passive loop which connects
right before the master volume in the
signal path. It is a line level loop so it is
recommended to only use high headroom
devices to avoid signal degradaon.
Plugging only into the return jack allows
the use of the JVM4’s power-stage,
overriding the preamp.
MASTER controls and the LINE OUT are
located aer the POWER AMP INSERT/
SERIAL LOOP so it is sll possible to take
advantage of those features when using an
external preamp. The loop can be taken o
the circuit by pressing the BYPASS switch
(the BYPASS/ACTIVE switch cannot be
programmed).
18. SERIAL / PARALLEL FX LOOP
JVM4 is equipped with a SERIAL/
PARALLEL FX LOOP. Connect your
external FX gear input to the SEND jack,
and the FX output to the RETURN jack. As
described previously, the FX loop can be
switched on/o from the front panel and
