INPUT PANEL

¼" INPUTS - left and right stereo
1
inputs for instruments.
RCA INPUTS - left and right stereo
2
inputs for -10dB consumer audio
electronics.
3.5mm TRS - input connection
3
for stereo -10dB consumer audio
electronics.
-15dB PAD - reduces the input level
4
by 15dB to prevent overload from
high output devices.
LIFT - disconnects the transformer
5
ground for the right channel only.

OUTPUT PANEL

XLR OUTPUTS - left and right
6
balanced 600 ohm, mic-level outputs
are 100% transformer-isolated.
GROUND - disconnects pin-1 on
7
both XLR outputs to reduce noise
caused by ground loops.

CONSTRUCTION

BOOK-END DESIGN - 14 gauge
8
s t e e l o u t e r s h e l l p r o v i d e s a
protective zone for the switches and
connectors.
FULL BOTTOM PAD - neoprene
9
covers the entire bottom and
provides electrical isolation and
plenty of friction to stay put on
hectic stages.
WELDED I-BEAM CASE - inner
10
steel enclosure is made extremely
rigid with I-beam profi le. Eliminates
stress that could torque the PCB and
cause solder joint failure.
MIILITARY-GRADE double-sided
11
PCB is bolted to steel standoff s for
toughness.
RADIAL TRANSFORMER - linear
12
freq. response from 20Hz to 18KHz
for natural sound. Mu-metal shield
t o e l i m i n a t e e l e c t r o m a g n e t i c
interference.
ISOLATED CONNECTORS are
13
made from extremely tough glass-
fi lled nylon for true electrical isolation
from chassis ground.
