RTS LMS-325
5W Active Modular Amplified Monitor Speaker

OUR PART #  LMS325


The RTS® Model LMS-325 Line Monitor Speaker Station is a modular amplified speaker that can be used to monitor one or two intercom or program channels.  It features 5 watts of drive power and includes a wide range 8 ohm speaker.  The LMS-325 is in the standard 1 RU, ½ 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.

The LMS-325 has separate phono jacks for each program input and an XLR-3 connector for a two channel RTS® intercom line.  A rear panel adjustment allows the user to set relative levels between the two input channels.  The LMS-325 is magnetically shielded to allow it to be placed adjacent to video monitors without affecting their display alignment.  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.

Features:

  • Dual channel inputs from RTS® TW Intercom or 2 separate program inputs.
  • Full Range 5 Watt Speaker and Power Amplifier
  • Standard 1/2 rack width 1 RU configuration, compatible with MCE-325, MRT-327, LMS-325.
  • Magnetically shielded enclosure allows for use adjacent to video monitors without picture degredation.
  • Locally powered to allow use with any audio or intercom source.

Specifications:

  • Impedance: 8 ohms
  • Power Rating: 5 watts
  • Sensitivity: 90± 2dB/2.83V/meter on axis averaged over one octave bands centered at 250 Hz, 500 Hz, 1kHz, 2 kHz, 4 kHz and 8 kHz when enclosed in a sealed box with a volume of 1.3 liters.
  • Frequency Response: 200 Hz to 10 kHz± 4 dB on 1/10 octave measurements in a sealed box with a volume of 1.3 liters.
  • Free Air Resonance: 200 Hz to 250 Hz
  • Stray Magnetic Field: Less than 1 gauss at a distance of 1 cm from chassis
