6.phono ground connector

Provides an earth-reference ground connection for a phono cartridge. One binding post labeled phono ground is available for a phono grounding wire. Connecting the phono grounding wire to the phono ground connector grounds the phono cartridge to the Nº 320S chassis, which sometimes reduces audible hum and other noise that results from multiple grounding paths. Otherwise, the ground connection between the Nº 320S and the associated phono cartridge is isolated.

Note

Listen to the associated phono cartridge both with and without the phono ground connection. Then, select the connection that results in the best performance.

7.trigger output connector

Provides 12 or 5V DC output to control connected components. One 3.5mm mini-jack labeled trigger output is available for a mono plug (Tip/Sleeve) connection. The Trig. parameter can be used to configure the trigger output connector to provide 12 or 5V DC output.

8.ir input connector

Provides input of 5V infrared signals with no more than 100mA of current from standard infrared distribution equipment such as IR repeaters. One 3.5mm mini-jack labeled ir input is available for a mono plug (Tip/Sleeve) connection. The tip of the mono-plug must have positive polarity as shown in the illustration to the left.

9.RS-232 port

Provides serial control, performing flash memory software upgrades and facilitating external control in AMX™ and Crestron™ systems. One 6-pin modular RJ-11 port labeled RS-232is available.

10.serial number label

Indicates the Nº 320S serial number, which is required for product registration and warranty service.
