Overview
The Telex LMS-325 is an amplified, modular speaker that can be used to monitor one (1) or two (2) intercom or program channels. It features 5 watts of drive power and includes a wide range 8Ohms speaker. It is in the standard 1 RU (Rack Unit), 1/2 rack width form factor of other RTS intercom products, including the RM-325 Intercom station, the MRT-327, MCE-325, SSA-324 and others. A large variety of mounting options and hardware are available to suit any application.
It has separate phono jacks for each program input and an XLR-3 connector for a 2-channel RTS intercom line. A rear panel adjustment allows the user to set relative levels between the two (2) input channels. The unit is powered locally from a supplied power pack to allow operation with dry audio signals and to prevent loading of the RTS TW intercom channels.
