Voltage Sync
Voltage Sync also is reliable if you choose and implement it correctly. The voltage sync inputs can detect the
control out voltage from a Niles signal-sensing product interfaced to the source component.
Obtaining Voltage Sync
Current Sensing
Current Sensing synchronizes a component by detecting the changes in the AC power draw that occurs with a
componentwhen it turns ON and OFF.
In Figure 19, when a CD changer is turned ON, a Niles APC-2 Current Sensing Switch senses the variation in
power consumption and outputs a 12V DC signal. The synchronized CD changer’s AC power plug connects to
the current-sensing outlet on the APC-2. The APC-2’s 12V DC output connects to the ZR-8630AV unit’s 12V Sync
Input dedicated to the CD changer using a Niles 10’ accessory cable with bare wire to mini-plug (FG00724, see
Accessories for more details).
The Niles APC-2 requires a minimum change of 30W for reliable current sensing. If the component does not
have a 30W change in current draw when turning ON (i.e., DSS receivers and most VCRs and CD players),
consider the last method, Light Sensing.
