The SLA range of 100v Line Attenuators (volume controls) offer the ability to control the level of individual Loudspeaker lines via an elegant, flush-mounting wall control plate.
Both Models - SLA50 (50W) and SLA100 (100W) - feature 10-step plus off-position notched control knobs, connected to high quality audio transformer and fitted to attractive single gang (SLA50) or double gang (SLA100) faceplates with contemporary screwless finish.
As well as volume adjustment, the units incorporate volume restoration facility, which will override the setting of the control knob and output the volume to full, when presented with a 24v DC control voltage.
