The Sonifex RB-SS10 10 way stereo analogue source selector/mixer is a 1U rack-mount unit that produces a stereo analogue audio output from 10 selectable stereo analogue sources. There are 10 illuminated front panel push-buttons, which select and indicate the current channel selection.The selection and indication is also available through a remote connector on the rear panel. To stop accidental front panel selection, there is a remote input to inhibit the front panel buttons.
Two of the stereo inputs are on XLR so that you can hot-plug audio sources, e.g. portable recorders. As well as being able to act as a source select module, the RB-SS10 can act as a mixer, by enabling the mix mode (using the remote input).
The gain for left and right inputs can be individually adjusted by using the pre-set potentiometers on the front panel. As well as routing the selected audio signal, the unit will also route a remote signal input through the remote connector to the selected input source, for starting external audio equipment such as a CD player.
The front panel headphone output has its own volume control, which is independent of the level adjustment for the main outputs, and has a maximum output level of +12dBu. The volume control can be made to also alter the output level of the main XLR outputs by using a switch on the rear panel to enable/disable this feature.
There is a designation strip on the front panel, useful for giving the buttons a meaningful description. The strip covers the input gain controls so that once configured, they can’t easily be altered – ideal for installation work. The LED on the front panel is used to indicate that power is present on the unit.
