SOURCE POWER SYNCHRONIZATION

Voltage Sync

Voltage Sync is also a reliable method of synchronization if chosen and implemented correctly. The 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 component when it turns ON and OFF.

Figure 19

In Figure 19, a Niles APC-2 Current Sensing Switch senses the change in power consumption of a CD chang- er when it is turned ON. When it senses that change, it outputs a 12V DC signal. The synchronized CD chang- er’s AC power plug is connected to the current sensing outlet on the APC-2. The APC-2’s 12V DC output is connected to the ZR-4630’s 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).

When using a Niles APC-2, a minimum change of 30W is required for reliable current sensing. If the com- ponent 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.
