Output Panel
PSC has really put
some thought in the
output capabilities of
the AlphaMix. It is
remarkable that the
output section of this
mixer supplies 3
balanced stereo
outputs, 2 TRS
stereo outputs and 1
mono output in
addition to the 4
direct outputs on the
Input Panel. The AlphaMix features dual isolated audio output transformers designed to
supply wide bandwidth and low distortion and interface with virtually any other device
including wireless transmitters. Furthermore, the dual transformers allow operator to
feed two cameras without interference.
Centered on the output panel are two 10 pin Hirose™ camera connectors. This
connector supplies balanced outputs for both left and right channels and provides tape
monitor returns.
CAMERA A
sends the same information as the L/R XLR outputs
located to the right of the Hirose connectors.
Toggle switches
below the XLR outputs
determine whether the signals for the XLR’s and CAMERA are at line level (+0dBv into
10k Ohm
9
loads) or mic level (-50dBv).
CAMERA B
is isolated electronically from
CAMERA A and is independently switched to line or mic level via the toggle switched
located below the output.
The
AUXILARY OUTPUTS
located above the right main XLR output are intended for
transcription. Both outputs are stereo 3.5mm TRS connectors wired: Tip = Left, Ring =
Right and Sleeve = Ground. These switchable outputs are located on the top panel
near the right side, just above the AUX OUT connectors. They will supply either line
level at -10dBv or mic level at -50dBv. If desired, the XLRs themselves could be used
in place of or in conjunction with the stereo mini-jack for DAT or audio tape recording.
In the upper left corner PSC has installed two multi-pin mini-jacks outputs. The 3-pin
jack supplies a balanced
mono feed
(labeled OUT)
. This is quite useful in sending a
wireless IFB feed to a producer, teleprompter or boom operator. Adjacent to the mono
feed is a 5-pin
GANG
output. This is an expansion port for future PSC accessories
including a soon to be released 2 channel expansion module that will increase the input
capability of the AlphaMix to 6.
The upper right corner features 4
auxiliary power outputs (AUX PWR OUT)
to power
wireless transmitters. An ENG/EFP audio package typically includes 4 such

The typical load imposed by most Betacams and other devices is 10K Ohms.
