IR VOLUME CONTROL 2CH PREAMP
Volume can be controlled by a 21958307 IR transmitter and a single- or dual-wired remote control.
When the wired volume control is moved, the volume will quickly fade up or down to match its position. When moving
a wired remote control, it is best to quickly turn the volume off then turn it up to the desired volume. This will eliminate
a sudden loud blast if the wired remote control was set at or close to full volume.
The IR transmitter Ch1+, Ch2+, Ch1-, Ch2- keys will raise and lower the volume.
The ROWELINK RCB LED should flash continuously at approximated 20 CPS.
The IR VOL COMM LED will flash when a Ch1+, Ch2+, Ch1-, Ch2- key is pushed.
