Description
The Pro Co iFace Portable Audio Player
Interface is a roadworthy aluminum-
housed device that allows simple and
reliable connection of stereo -10dBV
audio devices such as MP3 players,
Apple iPods, laptop computers and
consumer-type CD and DVD players
to the balanced microphone inputs of
professional audio mixing consoles.
The iFace provides both a 3.5 mm
(1/8”) and recessed left/right RCA inputs
for easy connection with standard
patch cables and a stereo/mono switch
to provide passive summing to a dual
mono feed where required.
The outputs are isolated
via audiophile-grade Pro Co MBT-1
Microphone Bridging Transformers and
appear on standard 3-pin XLR male
connectors. The transformers off er wide
bandwidth and low distortion and phase
shift, and are magnetically shielded in
mu-metal cans and electrostatically
isolated with dual Faraday shields. The
result is near-ideal rejection of common-
mode signals from all sources of RFI
and EMI, including radio pickup, SCR
dimmers and 60 Hz hum.
The ruggedly constructed
“Uni-Box” enclosure is formed of
extruded aluminum side channels and
16-gauge steel top, bottom and end
plates, designed to protect switches
and connectors from accidental
damage while also providing magnetic
shielding for the circuitry. Industrial-
grade connectors and switches provide
trouble-free reliability even in abusive
situations such as remote broadcast and
recording operations.
Controls:
STEREO INPUT:
3.5mm (1/8”) phone jack
accepts signals from unbalanced stereo
sources including desktop and notebook
computers and MP3 and DVD players
with nominal -10 dBV outputs.
INPUT IMPEDANCE:
Approximately
1.0 kohm.
LEFT/RIGHT INPUTS:
Recessed RCA jacks
wired in parallel to the STEREO mini
input.
STEREO/MONO SWITCH
: Provides
resistive mixing to combine stereo
sources for mono output for applications
where stereo operation is not required.
LEFT/RIGHT OUTPUTS:
Male 3-pin
XLR-type output jacks for connection
to standard balanced microphone
inputs of professional audio mixers.
Recommended input impedance:
1.0 kohm minimum.
