Introduction The GRAS 12AZ is a 8-channel CCP power module with gain for powering of prepolarized micro- phone sets. It is designed for use in a production environment, with a sturdy enclosure that offers protection against dirt, dust, and moisture.
LED on the front panel will warn about it. This warning indicates that the signal level exceeds what the 12AZ can handle without clipping. The remedy will be to lower the gain, see “Setting the Gain” on page 6. If you experience overload with the gain set to 0 dB, the remedy is to lower the input signal by using a microphone with a lower sensitivity.
Controls and Connections The Front Panel 12AZ has 4 LED status indicators for each channel. Green LEDs indicate the chosen gain setting. A red LED indicates DC-error or overload. The overload detector measures the voltage swing at the output and will be triggered if the signal exceeds 22 V .
