Signature SW 8:2+
8 Channel Source Selector/ Switch/ Mixer with PPM

Description Applications Specification Downloads Ask a Question

The Signature SW 8:2+ is a broadcast specification, 8 mono/ 4 stereo source selector switch/ mixer with PPM.

There are 8 balanced audio inputs on 3 pin Neutrik XLR sockets on the rear panel and these can be set globally to be 8 mono inputs or 4 stereo inputs. 

On the front panel there are 8 large illuminated buttons for turning sources on/ off. They work as 8 individual switches when in the mono mode and 4 pairs of stereo switches when the SW 8:2+ is set to stereo.

Two balanced Neutrik XLR plugs on the rear panel provide the output of the unit, which will either be one single mono channel or 1 stereo channel when the unit is set to ‘switch’ mode or a mix of all selected sources when set to ‘mix’ mode. 

Three rear panel dip switches allow for setting mix/switch, mono/stereo & output pre/post headphone volume pot.

The front panel features a 6.35mm stereo TRS jack socket for headphones monitoring, with a full size pot to adjust the volume level.  This headphone circuit monitors the output audio.

A stereo 28 LED Peak Programme Meter (PPM) is also provided on the front panel for a visual indication of the audio currently being routed/ mixed to the output. The PPM provides a 1dB resolution per LED.

Power is provided by an internal switch mode power supply, with a wide input range.  There is also an input for external +/-12V DC power.  The +/-12V DC input can be connected to the optional Signature PS1external DC Master Power Station, for situations where a redundant power supply is desirable.

Adding Multiple Sources to a Small Mixing Desk

A lot of low cost and entry level radio and general purpose mixing desks have great facilities but often lack in input channel numbers.
Adding a Signature SW 8:2+ is a convenient and easy way of turning 1 single channel strip on the mixer into 8 mono or 4 stereo mix sources.
This is normally a much more cost effective solution for adding extra occasional use channels to a desk than buying extra channel strips for the desk itself.
Being a Glensound Signature unit it is also a much better long term investment than adding extra channels to a low cost desk whose life span may well only be 5 years, whereas Glensound units normally have life spans exceeding 20 years.

Metering, Routing/ Selecting Different Sources to The Racks Room Monitor

Many racks rooms in studio complexes and other technical environments have multiple audio circuits routed to patch panels and transmission/ distribution chains.  Monitoring of these circuits with dedicated 1RU multi input broadcast monitoring subracks can be expensive and often a little limited by the small size and poor performance of 1RU rack loudspeakers.
The alternative is to use the 8:2+ source selector and your choice of standard active monitors which will provide a much better audio quality solution and depending upon your monitor choice will also be a much more cost effective solution. The SW 8:2+ with its addition of stereo 28 LED PPM meters make it an ideal device for metering levels in your racks room.
If the rear panel post/pre dip switch is set to post then the front panel volume pot will adjust the output level and act as a loudspeaker volume control.
The front panel headphone output also provides another solution to monitoring the sources if no monitor loudspeakers are required.
