The DRM 4000 is a rack-mixer and/or audio signal router offering eight audio inputs and two audio outputs. The inputs are divided into 4 MIC/LINE channels and four AUX channels. Each input channel can be freely assigned to either one or both output channels, offering mono two-channel operation, as well as, stereo operation modes. The DRM 4000 can be used as a pre-mixer for the DPM 4000, expanding the amount of available input channels. DRM 4000 and DPM 4000 can be linked via an RS-485 remote-interface. Priority functions, preset switching and routing are easy to configure and operate.

The DRM 4000 Mixer & Router can also be used as a stand-alone unit for simple sound reinforcement tasks, e.g. in a multimedia set-up, as well as for straightforward paging installations. Typical applications include the use as a mixer for sound reinforcement systems in conference rooms, multipurpose facilities, clubs, restaurants, houses of worship, etc.

With the addition of the RS-232 interface card, the presets of the DRM4000 can be configured to a variety of different routing, level and page ducking settings. This greatly expands the flexibility of the unit and these settings can be remotely triggered by commands sent through the DPM 4000 ProAnnounce CPU.

Priority functions, preset switching and routing are easy to configure and operate. The DRM 4000 Mixer & Router can also be used as stand-alone unit for simple sound reinforcement tasks, e.g. in a multimedia set-up, as well as for a variety of background music and paging installations.

Features

  • 4 XLR MIC/LINE input channels, 4 stereo RCA type AUX input channels
  • 2 XLR audio outputs
  • Level and tone control (Lo/Hi) in all input channels
  • Signal / Peak LEDs (green/red) for monitoring the input level in all input channels
  • Input channels can be independently assigned to the output channels and controlled via contact closures, optional RS-232 interface or from the DPM 4000
  • Direct outputs for all MIC/LINE and AUX-channels
  • Pre/Post internally configurable
  • Priority control (ducking function) in the inputs MIC/LINE 1 and 2; controllable via external contacts, signal level with adjustable threshold (on the front) or via remote control, indicated via LEDs on the front panel
  • Limiter in the inputs MIC/LINE 1 and 2 with internally selectable threshold
  • Separate summing controls and LED-chains for both outputs
  • VCAs in both output channels
  • Mix-input for external feeds / extension: 2x RCA-type, unbalanced, with level control on the rear panel
  • Send-output for recording / extension: 2x RCA-type, unbalanced
  • Remote control via external contacts: 8 freely configurable control inputs for ducking MIC/LINE 1 and 2, preset switching, routing, volume switching, mute
  • Optional serial RS-232 interface for PC or media-control
  • Optional serial RS-485 interface for connecting the DPM 4000
  • 24V power supply; optional mains adapter for 90-240V AC mains supply
  • Power-on delay: relay switching to prevent audible power-on / off switching noise

RS-232 Interface features (optionally available)

  • Direct control of all routing possibilities via PC.
  • Output level control via VCA.
  • Configuration and storage of presets as well as preset switching via PC.
  • Interface facility to connect to media control.

RS-485 Interface features (optionally available)

  • Controlling all routing possibilities from a DPM 4000 via macros.
  • Ducking control from a DPM 4000 via macros.
  • Output level control via VCA.
  • Configuration and storage of presets via the PROMATRIX Designer software.
  • Preset switching via DPM 4000.

Architectural and Engineering Specifications

The rack-mixer / audio signal router shall offer eight audio inputs and two audio outputs. The inputs will be divided into four MIC/LINE channels and four AUX channels. Each input channel shall be independently assignable to either one or both output channels, offering mono two-channel operation as well as stereo operation modes.

The unit shall be enabled for use as a pre-mixer for the DPM 4000, expanding the amount of available input channels. The DRM 4000 shall be capable of RS-485 communications with the DPM 4000. Priority functions, preset switching and routing shall be easy to configure and operate.

The unit shall also be enabled for use as a stand-alone unit for simple sound reinforcement tasks, e.g. in a multimedia set-up, as well as, for straightforward paging installations. The unit shall have four AUX input channels: each with two RCA-type connectors, volume and tone control (Lo/Hi) in all input channels, signal/peak LEDs (green/red) for monitoring the input level in all input channels and direct outputs for all MIC/LINE and AUX-channels. The unit shall also have priority control (ducking function) in the inputs MIC/LINE 1 and 2; and be controllable via external contacts, signal level with adjustable threshold (on the front) or via remote control, indicated via LEDs on the front panel. There shall be VCAs in both output channels providing two VCA control inputs A/B for remotely controlling the volume setting via external potentiometer, and also controllable via serial interface (PC, DPM 4000, media-control) or via control contacts. In addition there shall be remote control functionality via external contacts: eight independently configurable control inputs for ducking MIC/LINE 1 and 2, preset switching, routing, volume switching, mute.
