Microphone Splitter
FEATURES
1. -30dB PAD:
Allows ba4dB
line-level sources to connect to the
ProMS2 input.
2. Mic input:
Used to connect a low
impedance, balanced, microphone or
direct box.
3. Direct-1 thru:
A parallel direct
output used to bridge the mic or DI to
the primary mixing console.
4. Bookend design:
14 gauge steel
outer shell creates protective zone
around connectors and switches.
5. Full-bottom no-slip pad:
This
provides electrical isolation and
plenty of ‘stay-put’ friction to keep the
ProMS2 in one place.
6. Direct-2 output:
Equipped with
ground lift. Used to bridge the signal
to an additional audio device.
7. Lift (Direct-2):
Disconnects
pin-1 (ground) on the direct-2 XLR
output to help reduce hum and buzz
caused by ground loops.
8. Isolated output:
Transformer-
isolated to eliminate ground loop hum
and buzz. Used to bridge the balanced
mic signal to a second audio system.
9. Lift (Isolated output):
Disconnects
pin-1 (ground) on the isolated XLR
output to help further reduce hum and
buzz caused by ground loops.
