Product: Model 82 Stereo Analog Audio Distribution Amplifier
One Stereo Input
The differential input circuitry is compatible with balanced or unbalanced signals having a nominal level range of –12 dBV to +10 dBu. Laser trimmed, the inputs offer superior common-mode signal rejection. To achieve optimal audio performance the ExactCal calibration section matches the specific input levels with the Model 82's internal gain structure. Two 15-turn trim potentiometers and four LEDs allow fast, precise calibration.
With ExactCal, excellent audio performance can be achieved with little or no hassle. During normal operation, the ExactCal LEDs also serve as convenient signal-present indicators. Standard 3-pin XLR-type connectors are used to interface the input sources with the input circuitry. Manufactured by Neutrik, the connectors feature metal housings for reliable operation.
Four Stereo Outputs
The Model 82 contains four independent stereo output sections. For compatibility with a wide range of facilities, each output section can be independently configured for a –10 dBV or +4 dBu nominal output level. Each output features an electronically balanced circuit capable of driving balanced or unbalanced loads. Short circuit resistant, the rugged output circuits can drive full signal levels into 600 ohm or greater loads.
The Model 82's architecture precludes the need for individual output-level trim potentiometers. With the input signal calibrated using the ExactCal section, the four outputs use 1%-tolerance components to provide precise –10 dBV or +4 dBu outputs. Two XLR-type connectors are used to interface the four stereo outputs.
The Model 82 is the result of exacting circuit design combined with the latest state-of-the-art components. Like all Studio Technologies products, the Model 82 has survived tough listening evaluations by industry professionals. These veterans have the "ears" to guide us in achieving the right performance. The outcome is a product that achieves sonic excellence.
