AEV Xtreme II Digital Audio Processor Sec. 1 The Xtreme audio processor The Audio Xtreme II processor is a complete audio signal processing system for AM, FM and TV transmissions. The sound quality defines the station’s image and professionalism. The importance of the AUDIO PROCESSOR is therefore clear. The wholly digital technology with which Xtreme II was built means that the results obtained can IN NO WAY BE COMPARED with those of any other traditional processor.
AEV Xtreme II Digital Audio Processor Sec. 1-4-1 Analogue inputs/outputs The analogue inputs are installed on two XLR female connectors, located on the rear panel. The input is ≥10 KΩ high impedance, and the inputs accept signals up to +12dBu. The analogue outputs are provided with two XLR male connectors, located on the rear panel. The outputs can pilot loads of ≥10 KΩ. Sec. 1-4-2 Digital inputs/outputs The digital input is provided with an XLR female connector, located on the rear panel.
AEV Xtreme II Digital Audio Processor The display may be difficult to understand at power-up, therefore, set the contrast level (see the appropriate section) Sec. 3 Input/Output connections When connecting inputs/outputs, you are recommended to use a good quality, well shielded, soft cable. 0 0 Sec. 3-4 Remote control Xtreme II can be remotely controlled via an RS-232 standard serial port – this enables you to control it via both PC and modem.

Sec. 4-2 Adjusting the input level Play a piece of music ( CD ) with good dynamics and a rich sound. Adjust the mixer to obtain 0dB indication on the instruments.
AEV Xtreme II Digital Audio Processor Select Input Level and choose Change option. Now, the graphic display of the input level is available. This can be amplified or reduced of 12 dBu. By means of the Jog select a gain in order to have the processor operate around 0 dBm. At the end of the setting, return to Home initial menu. Sec. 4-3 Adjusting MPX coder parameters May we remind you again that any other pre-enphasis on your transmission chain must be disabled as it is generated by Xtreme II.
