VCM-88C Controller
The VCM-88C allows for accurate, low distortion level control without signal degradations
encountered when using mechanical controls or long signal paths. This unit adds
functionality and control in any system or installation where remote control or fast automatic
system response is required. Specific applications are discussed in detail on Page 8.
Connectors & Cables
Your VCM-88C is provided with a single connector type for audio signals in and out. All
connections are made via 1/4” stereo phone jacks (TRS), which can be used to connect,
balanced or unbalanced signals to the unit. Whenever possible, balanced connections are
recommend between all components in your system, as this eliminates ground-loop induced
hum and noise.

VCM-88C Audio Connector Polarities
All inputs are 20K ohm active balanced and 10K ohm unbalanced.
Note: The VCM-88C can be connected using a “single connector insert mode.” In this
configuration, the In jack functions as a TRS insert with the Tip receiving the input, the ring
the output and the sleeve acting as a common ground.
Remote control connections are made via Euroblock connectors. Polarities and other details
for those connectors are provided on the chassis.
Unbalanced Connections and Grounding
If you must use unbalanced connectors, the negative lead of the connector (ring) should be
tied to the ground lead (sleeve). Using unbalanced connections could result in chassis
ground-loop noise. Altering the signal/chassis ground relationship in equipment connected
to your unit may eliminate the noise.
