Remote Gain Attenuator
A 3 pin “Euro” connector has been provided to adjust the volume of the K Series loudspeaker or put the system 
into standby. (Figure 13) By varying the voltage on the    pin between +5V (provided on  pin) and 
ground (   pin), the volume can be linearly controlled. The voltage on the    pin can be created by using a 
potentiometer or provided from an external source. Many K Series systems can be controlled from a single poten-
tiometer by connecting the    pins of multiple K Series speakers together. 
A relay or manual connection can be made between the   pin and the    pin to put the K Series system into 
standby mode after 5 minutes.
WARNING: Do not put more than +5V or less than ground on the   pin or else damage may 
occur. Do not connect the    pin directly to the           pin.
