Description
Audio Mixer with Two Audio Buses for ENG Applications
The Model 742A Audio Mixer is expressly designed for use in electronic-news-gathering (ENG) vehicles and small production truck applications. Many other fixed and mobile audio production, on-air, and utility applications can also be supported. Model 742A features include four mic/line inputs with +48 volt phantom power, four line inputs, two output buses, LED level metering, flexible monitoring, and AC and DC powering. The Model 742A was specifically designed as a dual-channel audio mixer, rather than as a typical stereo device. This approach makes it excellent for "dual-path" on-air applications. As a utility mixer the Model 742A can create two independent monaural signals, excellent for general signal monitoring, talent cueing, or intercom support uses.
The Model 742A 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 742A is a refreshing combination of performance and simplicity. Using their experience in mobile broadcast applications, the engineers at Studio Technologies were able to design the Model 742A to include all the crucial features required to meet the needs of fast-paced news-gathering operations, while still providing the operator with an easy-to-use product.
The hallmarks of the Model 742A are application flexibility, simplicity in use, audio quality, and long-term reliability. For powering, the unit can be directly connected to an AC mains source. A true "universal input" design that's intended for worldwide use, the input voltage can range from 100 to 240 volts, 50/60 Hz. A source of 10 to 18 volts DC can also be connected to power the Model 742A. If both AC and DC sources are connected, the AC source will power the unit while the DC source will serve as a backup. In this way a battery can be connected, ready to serve in a standby capacity.
A carefully selected feature set ensures that the Model 742A will be a "team player" when it is integrated into an audio system. A number of internal configuration "jumpers" allow the unit's performance to be tailored to the needs of specific installations. And while there's flexibility on the inside, the operator is presented with an easy-to-use set of front-panel controls and indicators-the operator typically never has to access the back panel to operate the unit. In this way the goal of delivering successful on-air and production audio, day-after-day, can best be achieved. The Model 742A's audio quality is "pro" throughout. The components were carefully selected to deliver low-noise, low-distortion performance.
Long-term reliability was also part of the Model 742A's design criteria. To that end the unit's enclosure is made of lightweight yet rugged aluminum with a steel front panel for overall rigidity which adds to rack-mounting stability. On the inside, a conservative circuit design combines state-of-the-art integrated circuits for sonic quality with numerous filtering and protection components for long-term reliability.
