This is a range of control units offering source selection, volume, dim and cut controls for external analogue audio monitor loudspeaker feeds together with controls for studio illuminated signs. The models include a simple light controller only, a single stereo controller, a controller with a four stereo inputs and a 5.1 surround-sound version, with six balanced inputs and outputs. All are 1U rack-mounting designs.
RM-MCL - Light control only
This has three LED-illuminated buttons on the front panel, marked TX (Transmit), STANDBY and REH (Rehearse). The TX and REH buttons control opto-isolated outputs to provide a direct control interface to Sonifex SignalLed illuminated studio signs, allowing twin signs to be controlled individually. The Standby button, when pressed, initiates a two-minute count-down during which the TX and REH buttons and associated outputs flash alternately. After the two minutes, the TX light remains on. The rear panel has a 15-pin D-sub connector for the remote connections. These include open-collector tally inputs for TX and REH as well as remote control inputs for the TX, Standby and REH controls. A DC power source is also supplied at 200mA maximum. As a result the controllers can be interfaced with most illuminated studio signs. Power is applied to the unit via an IEC connector on the rear. Technical specifications are as follows. Power source: 85-264V AC, 47-63Hz. Dimensions: 480 x 108 x 43mm (w x d x h mm. Weight: 1.3kg approximately. Included accessories: Manual, AC power cable.
RM-MC1L - Single stereo input, one stereo output - Light control
In addition to the features described for the RM-MCL, this has two further buttons, marked ‘DIM’ and ‘CUT’, and a rotary volume control. The volume control adjusts the attenuation of the outputs from 0dB down to 86dB. The dim control reduces level by a pre-set amount from 2db to 23dB, set using a control on the rear. The cut control mutes the outputs. The rear has, in addition to the connectors fitted to the RM-MCL, two male XLR inputs and two female XLRs for outputs, intended to work with line-level audio circuits. The remote control connector has connections to operate the dim and cut functions remotely. Technical specifications are as the RM-MCL, except the following. Inputs: +25dBu maximum, 20k ohms. Attenuation: 0 to -86dB . Dim attenuation: -3dB to -23dB. Common mode rejection: 66dB, typical. Distortion: Less than 0.04%, +8dBu. Crosstalk: -80dB, 1kHz input, 0dBu. Outputs: +25dBu maximum, 50 ohms. Included accessories: Manual, AC power cable.
RM-MC4L - Four stereo inputs, one stereo output - Light control
In addition to the features described for the RM-MC1L, this has an additional four led-illuminated switches labelled 1 to 4, which provide the facility to select one of four stereo inputs to be monitored. The rear panel has an additional six female XLR connector for the three additional stereo inputs. Technical specifications are as the RM-MC1L. Included accessories: Manual, AC power cable.
RM-MC51L - Six inputs, six outputs - 5.1- Light control
Suitable for the control of 5.1 surround-sound monitoring systems, or as a global volume control for 6 separate systems, this has the same controls on the front panel as the RM-MC1L except that the level, dim and cut controls are controlling six, rather than two, channels. The rear panel differs from the RM-MC1L in that it has six male and six female XLR connectors for the inputs and outputs respectively. Technical specifications remain the same as the RM-MC1L. Included accessories: Manual, AC power cable. Included accessories: Manual, AC power cable.
