INPUT PANEL
1. ¼” INPUT & THRU - input connection
for instruments and thru-put for on-stage
amplifi er.
2. 3.5mm TRS - input connection for stereo
-10dB consumer audio electronics.
3. RCA INPUT - left and right input
connection for stereo -10dB consumer
audio electronics.
4. RCA THRU - left and right parallel thru-
put of signals connected to the ¼”, 3.5mm
TRS and RCA inputs.
5. -15dB PAD - reduces the input level
by 15dB to prevent overload from high
output devices.
6. XLR INPUT - this recessed switch
selects between the hi-Z and the XLR
inputs.
OUTPUT PANEL
7. XLR LINE INPUT - this XLR input is
specifi cally designed to accept +4dB line-
level signals from balanced sources.
8. GROUND LIFT - disconnects pin-1 on
the XLR output connector to help reduce
noise caused by ground loops.
9. XLR OUTPUT - balanced, 600 ohm,
mic-level output is 100% transformer-
isolated and compatible with mic splitters
and console preamps.
CONSTRUCTION
10. BOOK-END DESIGN - 14 gauge steel
outer shell provides a protective zone for
the switches and connectors.
11. FULL BOTTOM PAD - neoprene foam
foot provides electrical isolation and plenty
of friction to stay put on hectic stages.
12. WELDED I-BEAM CASE - inner steel
enclosure is made extremely rigid with I-
beam profi le. Eliminates stress that could
torque the PC board and cause solder
joint failure.
13. MILITARY-GRADE - double-sided PCB
is bolted to steel standoffs for toughness.
14. RADIAL TRANSFORMER - linear freq.
response from 20Hz to 18kHz for natural
sound. Mu-metal shield to eliminate
electromagnetic interference.
15. ISOLATED CONNECTORS - are
made from extremely tough glass-fi lled
nylon for true electrical isolation from
chassis ground.
