IMPORTANT SAFETY INSTRUCTION – READ FIRST
This symbol, whenever it appears,
alerts you to the presence of
uninsulated dangerous voltage
inside enclosure-voltage that may be
sufficient to constitute risk of shock.
Read Instructions: Retain safety and operating instructions for
future reference. Heed all warnings printed here and on the
equipment. Follow the operating instructions printed in this us er
guide.
Do not open: There are no user serviceable parts inside. Refer
any service work to qualified technical personnel only.
Grounding: Only connect the unit to equipment with properly
grounded mains power. Do not defeat the grounding and
polarization means of the power cord plug of the connected
equipment. Do not remove or tamper with the ground
connection on the power cord of the connected equipment.
Environment: Protect from excessive dirt, dust, heat, and
vibration when operating and stori ng. Avoid tobacco as h, drink
spillage and smoke, especially that associated with smoke
machines.
Handling: Protect the controls from damage during trans i t. Use
adequate padding if you need to ship the unit. To avoid injury to
yourself or damage to the equipment, take care when lifting,
moving or carrying the unit.
Servicing: Refer servicing to qualified technical personnel.
This symbol, whenever it appears,

Please read the manual.
Installation: Install the unit in accordance with the ins tructions
printed in the user guide.
INTRODUCTION:
Thank you for purchasing Applied Research and
Technology’s SPLITComPRO. The ARTcessories
SPLITComPro is an ideal audio utility to use in an
application where you need to split a low impedance
microphone signal to feed two separate mixers, or
where it’s necessary to combine balanced low
impedance microphone signals from two microphones
into a single channel input.
APPLICATIONS:
AS A SPLITTER: The SPLITComPro provides one
direct-coupled output and one isolated output from a
single microphone. Applications include sending the
direct output to the main or FOH mixer, and the second
isolated output to a monitor or recording mixer. The
MAIN MIC OUTPUT passes phantom power from the
main mixer to the MAIN MIC INPUT for use with
condenser microphones. Phantom power is blocked
from passing to the ISOLATED MIC OUTPUT.
AS A COMBINER: The SPLITComPro provides one
output from two microphone inputs. The PHASE switch
can be used to invert the relative phase of the
ISOLATED MIC INPUT. Applications include dual
miking of percussion instruments, choirs, and instrument
amplifiers. Phantom power passes through each output
to their respective input, (MAIN to MAIN, ISOLATED to
ISOLATED), however phantom power is blocked from
passing between the MAIN and ISOLATED signal paths.
Only the audio passes between the MAIN and
ISOLATED signal paths (it is present on all inputs and
outputs).
The SPLITComPro includes a GROUND switch that, in
the LIFT position, will provide full ground isolation
between the MAIN MIC INPUT (& OUTPUT) and the
ISOLATED MIC INPUT (& OUTPUT) to reduce noise
due to ground loops between connected AC-powered
units.

Note: A ll of the measurements made from the ISOLATED MIC
OUTPUT with PHASE switch out (NORM) and a 150 Ohm
balanced source feeding the MAIN MI C INPUT and a 1k Ohm
load c onnected to the ISOLATED MIC OUTPUT to simulate a
typical "real world" microphone and mic preamplifier. 0dBu =
0.775VRMS
