Remote Gain Attenuator
A 3-pin “Euro” connector is provided to attenuate the volume of the KW Series loudspeaker
or put the system into standby from a remote location. The Remote Gain connector can
only attenuate the output signal level below the level set by the Channel A and Channel B
Gain knobs.
By varying the voltage on (pin 2) between (pin 1) and (pin 3, ground), the
volume can be linearly controlled. The voltage on can be created by using a potentiometer
or provided from an external source. Many KW Series systems can be controlled from a single
potentiometer by connecting the pins of multiple KW Series speakers together.
A relay or manual connection can be made between (pin 2) and (pin 3, ground) to
effectively mute the output and put the KW Series system into standby mode after 5 minutes.
CAUTION: Do not put more than +5V or less than ground on (pin 2), or damage may
occur. Do not connect +5V (pin 1) directly to (pin 3, ground).
