Product Description
RDL ST-IC1 Intercom Amplifier
Overview
The ST-IC1 Intercom Amplifier from RDL is a professional-quality compact intercom amplifier ideal for situations where an intercom system is going to be installed or where an amplifier is needed to increase a mic level signal up to a 1W speaker level.
Part of RDL's Stick-On Series, this compact amplifier features screw terminal connectors for input, output, power, and muting. A simple screw control allows you to adjust the gain. The amplifier can accept a dynamic mic, condenser mic, and an 8- or 45-Ohm speaker. The output will drive more than 1W RMS into an 8-Ohm load and can be connected to any load impedance that is 4 Ohms or more.
