Baldwin Boxall RMON23 Operating instructions

  • Hello! I've reviewed the Operating Instructions for the RMON23 Monitor Panel by Baldwin Boxall. This document provides information on how to use the panel to monitor up to 23 loudspeaker lines, featuring a headphone socket, adjustable volume, and an LED level indicator. I'm ready to answer any questions you might have about device.
  • What type of headphones can be used with the monitor panel?
    Does the monitor panel have a volume control?
    Does the LED level indicator change when the volume is adjusted?

RMON23 MONITOR PANEL
The RMON23 is a 2U rack mounting monitor panel that enables monitoring of up to 23 separate
loudspeaker lines or zones.
Connection is from the 100V line output, of the desired number of amplifiers, to the 23 pairs of
terminals provided.
A headphone socket is provided on the front panel which will mute the internal speaker if used.
The loudspeaker has a maximum output of 1W. Both the headphone and/or the speaker volume are
adjustable down to zero via a twelve way switched potentiometer.
The headphone socket will accept a 1/4" Stereo Jack Plug for standard headphones (although the
signal is still only mono).
The monitor panel also has a four step LED level indicator to show the selected signal level. This
indication is independent of the volume setting.
