A) LIMITER IN. This is a balanced input that allows you to get a signal straight into the opto-limiter without
going through the mic pre and EQ. As soon as you insert a plug into this jack, it breaks the normal signal path
from the EQ. The pin-out is as follows:
TIP = +, hot or positive going signal
RING = -, low or negative going signal
SLEEVE = Ground (shield)
B) MIC IN. This is where you plug in the mic cable. Because this input has up to 50 dB of gain and can have
Phantom power, we strongly suggest that the INPUT ATTENUATE and/or monitor level is turned way down to
avoid huge pops or thumps when you plug a cable in here.
Pin 1 = Ground (shield)
Pin 2 = +, hot or positive going signal
Pin 3 = -, low or negative going signal
C) BALANCED LINE OUT. This is the final output after the Mic Pre, EQ and Opto-Limiter. It is ONLY meant to
drive balanced inputs. If one uses this XLR to connect to an unbalanced input expect some low level
distortion and a 6 dB loss. It is not a pseudo-balanced, transformer-like floating output typical on much gear
that is meant to be tolerant of any patching. Why not? No Op-Amps used here (pretty much needed for that
trick) and most of those circuits don't seem to sound great. If you need to feed an unbalanced input just use
the UNBALANCED OUTPUT.
Pin 1 = Ground (shield)
Pin 2 = +, hot or positive going signal
Pin 3 = -, low or negative going signal
D) OUT UNBALANCED ONLY . Use a regular 1/4" plug here to connect to an unbalanced or balanced input.
The nominal output here is +4dBm and not the -10dBu "consumer" level found on some budget semi-pro
gear. To feed that kind of input, you have to turn down the INPUT ATTENUATOR or better yet, the Limiter's
GAIN and ignore the VU meter which is set up for +4 levels.
TIP = +, hot or positive going signal
SLEEVE = Ground (shield)
E) FUSE. This is a 1/4" 1 amp slo-blo fuse. The fuse is a protection device intended to protect you and the
unit in case something is very wrong. Sometimes it is just the fuse that fails for some unknown reason, so if it
blows and you can't power up the unit, try another fuse (same type and value). If it blows too, prepare to send
in the unit for repair.
F) POWER. This is where the power cable gets plugged in. You Dual Vocal Combo should come with an IEC
power cable appropriate for your country and voltage.
G) GROUND TERMINALS. These 'ground posts' are intended to help in some installations particularly where
a special audio grounding scheme is used. The top post is the audio circuit ground and the bottom is chassis
and AC third pin ground. For almost all applications these posts are connected together with a strap or solid
piece of wire. If you are getting hums and buzzes, this is a good place to start experimenting, and why we
include them.
