manual abstract
Front panel controls provide a fine adjustment for an exact match into whatever component follows the AS 8 in the signal chain. Simple, accurate level adjustment is assured by a single front panel knob for each channel, which simultaneously adjusts the input gain and the level of participation in the gain allocation. Individual channel levels can be accurately adjusted by ear, using nothing other than a talker's voice as a sound source. The AS 8 is easily configured for transparent operation in any sound reinforcement, teleconferencing or recording application. Multiple units can be "daisy chained" for more than 8 channels. Connections for remote control pots or switches are provided for individual channels and for the overall mixed output. An RS-232 port allows most of the functions of the AS 8 to be controlled either by a computer or a dedicated control system such as AMX or Crestron. The current version of the software can also be downloaded from the Web site. The AS 8 TC features low and high frequency shelving controls on each inputchannel.

Dimensions: 13/4 x 8 x 19 inches Architects and Engineers Specifications The automatic microphone mixer shall incorporate an adaptive proportional gain mixing technique and automatic skewing between input channels to minimize comb filtering. The mixer shall contain eight input channels. Each input shall be electronically balanced and be capable of receiving mic or line level input signals. Phantom power shall be provided for each input as well as a direct output. (For Model AS 8 TC: Each input shall incorporate both a high frequency and low frequency tone control.) The main output shall be electronically balanced and have an integral compressor/leveler and master level control. Expansion ports shall provide IO access to the main and mix audio busses. The mixer shall be controllable via an RS-232 serial port and shall adhere to the LecNetTM communication protocol. The mixer shall meet the following performance criteria. Frequency response: 20 Hz - 20 kHz. THD < 0.1% @ +10 dBu output. IMD < 0.1% @ +10 dBu output. Input Impedance: > 2.5K ohm. Maximum Input Level: +20 dBu @ 0 dB setting; -10 dBu @ +30 dB setting; -30 dBu @ +50 dB setting. Equivalent Input Noise: -126 dB @ +50 dB gain. Maximum Output Level: +26 dBu. Maximum Gain: 75 dB (input to output). The mixer shall be rack mountable and occupy 1 RU. The automatic microphone mixer shall be the AKG Acoustics Model AS 8 (AS 8 TC).
