Control I/O Connections - B&K Phono10 Owner's Manual

Table of Contents

A control input/output is provided on the Phono 10 preamplifier to remotely turn the unit on and off. A receiver or

preamplifiers control output, such as is provided with the B&K series, can be utilized to provide a control signal to

the Phono 10. If a B&K amplifier is also being used, the control signal can be extended to include each

successive component by simply running a 1/8 inch mini jack cable from the CONTROL OUT connector of the

Phono 10 to the CTRL IN connector of the amplifier. This is commonly referred to as "daisy chaining". An example

of how to connect these components is illustrated in Figure 4.

If a source other than a B&K receiver or preamplifier is used to control the Phono 10, only the control output

voltage from the source is critical. It must be within the range, as indicated on the rear panel, 5 - 24V DC. The

Phono 10's CONTROL OUT will provide each successive component with a control voltage of 12V DC for reliable

operation. The Phono 10's control output may be used as a source of 12V DC @ 35 mA for other user

applications as well. DO NOT POWER MOTORS WITH THIS CIRCUIT!

If the control function is desired, each component in the system must remain connected at all times and the

control must be enabled. To enable the control function, the CONTROL ENABLE button must be out for each

controllable component in the system. For more information on the Phono 10's output status under various control

conditions, refer to (Table 2).

NOTE: The control voltage is for muting control only. Each component must be connected to its own source of AC

power in order for it to operate.
