Skokie, IL (September 27, 2012)—Studio Technologies, Inc. has introduced the Model 742A Audio Mixer, a dual-audio-bus mixer designed specifically for use in electronic newsgathering (ENg), small scale production trucks and utility applications.
An update to the Model 742, the new unit’s resources include four mic/line inputs with 48-volt phantom power, four dedicated line-level inputs, two main and two monitor output buses. Also included are LED level metering, flexible monitoring and AC/DC powering. The Model 742A is not a “stereo” mixer, but can create two independent monaural signals.
Operators who deal with multiple audio sources can use the 742A to create one or two independent audio-mixes. Each mic/line input channel is equipped with an input sensitivity button, rotary level control, signal level status LED and output bus assignment switch. To support condenser microphones, the four mic/line inputs can be individually configured to supply 48-volt phantom power. The four dedicated line-level inputs include a rotary level control, level status LED and output bus assignment switch. The compressor circuits associated with the two output buses can be configured to operate from one of three modes: a factory-set 6 dB above the main outputs’ nominal +4-dBu operating level, 2 dB above the nominal level or a settings where the compressors are turned off.
The 742A delivers a frequency response of 20 Hz to 20 kHz, ±0.5-dB (mic/line in to main outs) with a THD+N distortion level of 0.03 percent. The unit has a signal-to-noise ratio of 74 dB, referenced to +4-dBu output and offers a maximum output of +26 dBu into 10 k ohms, +25 dBu into 600 ohms.
