The Studio Technologies Model 742 Audio Mixer is expressly designed for use in electronic-news-gathering (ENG) vehicles, small production trucks, and other specialized mobile broadcast applications. Many other audio production applications can also be supported. Model 742 features include four mic/line inputs, four line inputs, two output buses, LED level metering, and flexible monitoring. The Model 742 was specifically designed as a dual-channel audio mixer, rather than as a typical stereo device. This approach makes it excellent for use in "dual-path" on-air applications.
The Model 742 is targeted for use by operators with numerous audio sources that need to be quickly and reliably adjusted and routed to create one or two independent audio mixes. In these days of operators having too many tasks to handle, and too little time to do them, the Model 742 is a refreshing combination of performance and simplicity.
Mic/Line Inputs
Four input channels are provided for connection to microphone or line-level signals. The electronically balanced circuitry is "ruggedized" for reliable operation under tough operating conditions. The low-noise, low-distortion, high-headroom audio performance is what's expected of sophisticated "pro audio" equipment. Features provided for each input channel include an input sensitivity button, rotary level control, signal level status LED, and output bus assignment switch.
For ease of use, each input's rotary level control sets the gain of the input circuit as well as the level being sent to the selected main output bus (or buses). For convenience the input sensitivity button, as with the other Model 742A operator controls, is located on the front panel.
Line Inputs
Four input channels are provided for connection to line-level signals. Features provided for each line input channel include a rotary level control, level status LED, and output bus assignment switch. The rotary level control is used to set the amount of input signal that is sent to the selected main output bus (or buses). The dual-color level status LED provides signal present and peak level indication. A 3-position switch allows the input signal to be assigned to the desired output bus (or buses).
