MP522 Microphone / Line
1. INTRODUCTION
The MP522 preamp was designed for use with Ampetronic Induction Loop
drivers, but can be used in other applications as a separate seven input
pre-amp. The unit is designed to amplify five microphone channels by a
maximum of 46 dB, and two line-level inputs by 6 dB.
Each channel has an electronically balanced input. Microphone channels
use XLR input connectors, with phantom power facility. Balanced line-level
inputs use 6.3 mm jack sockets. A gain control is provided for each channel,
and the combined output signal is electronically balanced.
Power for the preamp is normally obtained from the host Ampetronic
amplifier, but the unit can be powered from a small, separate power supply,
Ampetronic type PS3.
2. INSTALLATION
The unit is designed to be used in a clean and professional environment. If
used with the ILD122 range of loop drivers, the preamp can be installed in
the RM-1U rack mount kit with the correct blanking plate.
