    MODEL 34 - Overview

    The Model 34 is intended for use by on-air broadcast and production support personnel. The unit provides two user-accessible rotary level controls and an output mode switch. The switch is used to select how the one or two audio input sources are routed to the connected earpiece or headset. In the switch's stereo position input channel 1 (XLR pin 2) is sent to the left output channel while input 2 (XLR pin 3) is sent to the right output channel. The two controls allow the left and right output levels to be independently set. When the output mode switch is set to the mono position, a "mix" of input channels 1 and 2 can be created. Using the level controls, camera or production personnel can create a unique cue mix of either or both audio inputs. This allows independent IFB signals, such as those intended for use by on-air talent and technicians, to be simultaneously monitored. By design, the Model 34's level controls cannot be set to fully attenuate ("mute") the input sources. This helps to ensure that users will never accidentally miss important "cues" from directors or producers. While audio quality is not normally considered a factor in IFB or intercom systems, the Model 34 is built to "pro audio" standards. This helps to ensure that the best possible audio reproduction is provided.

    The Model 34 is compatible with virtually every standard broadcast IFB and party-line intercom circuit. This type of circuit typically uses 3-pin XLR-type connectors for interfacing with connected equipment. XLR pin 1 serves as common for DC power and audio. Pin 2 provides DC power and, in the case of a dual-channel circuit, DC power and channel 1 audio. Pin 3 provides channel 2 audio in dual-channel systems or channel 1 audio in single-channel systems.

    Model 34 units have been tested for correct operation with IFB and intercom circuits associated with systems from RTS, Clear-Com, and Studio Technologies. Good performance can be expected when the Model 34 is used with IFB circuits associated with the ubiquitous RTS Model 4010 Central Controller and IFB-828 Interface. With IFB circuits provided by interface units from Studio Technologies, excellent audio quality and support for lengthy cable runs can be expected.
