MODE SWITCH.
Used to set phase* and to bypass crossover for Low Level input**.
Position 1 / Line: 0 degrees phase, crossover engaged low level input
Position 2 / LFE: 0 degrees phase, crossover bypassed for low level input
Position 3 / Line: 180 degrees phase, crossover engaged for low level input
Position 4 / LFE: 180 degrees phase, crossover bypassed for low level input
*Phase selection affects both Hi and Lo level inputs
**Crossover is always engaged for Hi level input regardless of mode switch
position.
LO LEVEL
input volume control. Adjust for output level when using LO LEVEL phono
input or balanced line level input XLR socket.
HI LEVEL
input volume control. Adjust for output level when using HIGH LEVEL
UNBALANCED INPUT Neutrik socket or HIGH LEVEL BALANCED INPUT Neutrik
socket.
FINE ROLL OFF
control. Fine adjustment of roll off point, used in conjunction with
Coarse Roll Off control (below). See chart on amplifier panel or in this manual, page 8,
for crossover frequencies determined by setting combinations of both controls.
COARSE ROLL OFF
control. Coarse adjustment of roll off point, used in conjunction
with Fine Roll Off control (above). See chart on amplifier or in this manual, page 8, for
crossover frequencies determined by setting combinations of both controls.
0dB LO INPUT
phono socket. Used to connect the Sub Bass System at low level to
the sub/LFE output of the amplifier/processor or left and right pre-amp outputs.
If Lo Level inputs are used to connect pre-amp right and left outputs then a 12dB
attenuator is available from REL to balance the two inputs.
+12dB LO INPUT
phono socket
. As
6 but a higher
sensitivety. If LO LEVEL inputs
are used connected to pre-amp right and left outputs then a 12 dB attenuator is
available from REL to balance the two inputs.
HIGH LEVEL BALANCED INPUT.
Neutrik Speakon socket.
Used to connect the Sub
Bass System at high level to the speaker output of one channel of a differential output
or bridged to mono amplifier.
HIGH LEVEL UNBALANCED INPUT.
Neutrik Speakon socket. Used to connect the
Sub Bass System at high level to the main speaker output of amplifiers.
LOW LEVEL BALANCED INPUT.
XLR socket. Used to connect the Sub Bass System
at low level to pre-amplifier balanced line outputs.

and potential additions to panel graphics on preceding pages.]
