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 | – Figure 13 – |
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.
