INPUT PANEL
¼" INPUTS - left and right stereo
inputs for instruments.
RCA INPUTS - left and right stereo
inputs for -10dB consumer audio
electronics.
3.5mm TRS - input connection
for stereo -10dB consumer audio
electronics.
-15dB PAD - reduces the input level
by 15dB to prevent overload from
high output devices.
LIFT - disconnects the transformer
ground for the right channel only.
OUTPUT PANEL
XLR OUTPUTS - left and right
balanced 600 ohm, mic-level outputs
are 100% transformer-isolated.
GROUND - disconnects pin-1 on
both XLR outputs to reduce noise
caused by ground loops.
CONSTRUCTION
BOOK-END DESIGN - 14 gauge
steel outer shell provides a
protective zone for the switches and
connectors.
FULL BOTTOM PAD - neoprene
covers the entire bottom and
provides electrical isolation and
plenty of friction to stay put on
hectic stages.
WELDED I-BEAM CASE - inner
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
PCB is bolted to steel standoff s for
toughness.
RADIAL TRANSFORMER - linear
freq. response from 20Hz to 18KHz
for natural sound. Mu-metal shield
to eliminate electromagnetic
interference.
ISOLATED CONNECTORS are
made from extremely tough glass-
fi lled nylon for true electrical isolation
from chassis ground.
