Introduction 10-Channel stereo preamplifiers The PRE2xx series preamplifiers are solutions for applications where a large number (up to 8) of microphones (or other mono balanced audio inputs) need to be mixed to two output zones. The multifunctional stereo design with a total of 10 inputs allows connection for any type of audio source such as microphones, Bluetooth devices or line level audio sources.

POWER SUPPLY AND POWER CORD REQUIREMENTS Power supply class I grounding requirements: For protection from fault currents, the equipment shall be connected to a grounding terminal. Plug the system power cord into an AC outlet that provides a ground connection. Substitute cords may not provide adequate fault protection.
Chapter 1 Pin connections and connectors CONNECTION STANDARDS The in- and output connections for AUDAC audio equipment are performed corresponding to international wiring standards for professional audio equipment. Cinch (RCA): For unbalanced line input connections Tip: Signal White: Left Sleeve: Red: Ground Right XLR: For balanced signal input connections Pin 1: Ground Pin 2: Signal + Pin 3: Signal - 3-Pin Terminal Block: For balanced signal input & link output connections.
Chapter 2 Front & rear panel Front panel overview Front panel description Input mixing controls: Using the input mixing controls, the individual level for each input can be adjusted. Each input control is provided with a clip indicator LED which illuminates when the maximum level (clipping) is almost reached. To ensure the best signal-to-noise ratio, illumination of this indicator should only occur at peak levels.
When pairing with your device for the first time, the ‘PAIR’ button should be pressed and the LED will start blinking for about 2 minutes. During this period, the device can be discovered and is indicated as Bluetooth ID ‘AUDAC PRE series xxxx’ (where the xxxx stands for an unique ID for each single device). When both devices have been paired before, the transmitter will be recognized by the receiver and will allow continuous pairing without pressing the ‘PAIR’ button. 3.5 mm Jack input (CH2): A 3.
Rear panel description AC Power inlet with fuse: The mains power supply (100-240V AC - 50/60 Hz) has to be applied to this AC power inlet. The connection is made by an IEC C14 power connector and is fitted with a fuse. When replacing the fuse, make sure that the value of the replacement fuse matches the value of the original fuse. (T500mAL/250V) Balanced stereo line output: The balanced stereo line outputs are implemented using two 3-pin terminal block output connectors.
Enabling phantom power & talkover Phantom power: The phantom power switches on the rear side of the pre-amplifier enable phantom power (48V) to the inputs for powering condenser microphones. The first switch ‘MIC 1’ enables phantom power to the first input, the second switch ‘MIC 2’ enables phantom power to the second input while switch ‘Mic 3-8’ enables phantom power to all other microphone inputs.
