Installed Sound

Q. We need a simple way of controlling levels (mostly too loud!) on an in-store music system we’ve installed. The client has found that the CDs they are supplied with have greatly varying volumes and they don’t want to have to continually turn the volume up and down.

A. The RB-SL2 is a stereo (or dual mono) VCA limiter ideal for use in this situation. Each channel has an input gain and a threshold level control. Setting the limit level to maximum (fully anti-clockwise) enables the input through to output to be normalised using the input gain potentiometers.

Once the unit is acting as a buffer with gain/attenuation, the limit level can be set, with the recovery adjusted for the application. Limiting is indicated by the power LED on the front panel flashing.

Radio Operations

Q. We find we get widely differing levels on incoming telephone callers our presenters aren’t catching the big peaks when they shout.

In dual mono mode it can be used on two independent telephone balance units whilst in linked (stereo) mode it could be used on an ISDN feed.
