front panel, allow the interrupt function to be configured; one switch selects whether the monitor speaker output will be inter- rupted by the AUX signal, the other whether the headphone output will be interrupted.

Configurable Outputs

Four monaural, balanced, line-level out- puts can serve in a wide range of installa- tion-specific applications. DIP switches, located on the back panel, are used to select from the five available signal sources: main output left, main output right, AUX output left, AUX output right, and mic/line input channel direct. The DIP switches can be set to provide additional stereo outputs, create monaural outputs from the main or AUX outputs, or to pro- vide direct outputs from the mic/line input channels.

Monitor Section

Reminiscent of much larger audio con- soles, the Model 750’s monitor section gives the operator an extensive set of resources. Separate stereo outputs and level controls are provided for connection to a monitor amplifier and headphones. In addition to monitoring the main and AUX audio buses, provision has been made for monitoring two external audio sources. These stereo inputs are intended to be connected to off-air, microwave, or satel- lite receivers. External Monitor Input 1 is compatible with “+4” signals, while Exter- nal Monitor Input 2 can be set, using a front-panel DIP switch, for “–10” or “+4” compatibility.

Multiple sources can be simultaneously selected for monitoring. This can prove useful by allowing, for example, an opera- tor to simultaneously monitor a local mix

and an externally-provided mix-minus signal. A mono function allows the moni- tored audio source to be checked for phase cancellation problems and accept- able “sum-to-monaural” performance.

The AUX interrupt mode allows monitoring of selected input channels and the setup section without interfering with normal operation of the main audio bus. For operator assistance, the meters can be configured to monitor the AUX bus when- ever the AUX interrupt mode is active.

Mechanical VU-type meters, along with peak level LED indicators, provide a “user- friendly” indication of audio-signal levels. Fanatics for addressing the details, Studio Technologies has even eliminated the issue of burned-out meter-scale illumina- tion by implementing a solid-state, LED- based lighting scheme.

Setup Section

Unique to the Model 750 are the features provided by the setup section, the high- light being the ability of the operator to record and playback three voice identifica- tion segments. The Left+Right segment allows a voice message of up to 12 sec- onds in length to be recorded, with play- back going to the left and right output channels. The Left Only and Right Only segments allow recording of up to 4 sec- onds each, with playback going only to their respective channels.

The voice segments can prove useful, allowing the facilities that receive the vehicle’s signal (generally provided by microwave or satellite links) to quickly “learn” more about the origin of the trans- mission. Information such as vehicle identity, physical location, the names of technical and on-air personnel, mobile
