Unbalanced inputs, Trigger connectors | Lyngdorf Audio SDA 2175

Unbalanced inputs

The unbalanced RCA inputs are wired in accordance with normal practice:

Shell: Chassis and ground.

Pin: Hot (+).

When the unbalanced inputs are used, the input selector switch MUST be set to the UNBALANCED position. The switch position can be changed with a small screwdriver.

The switch must be changed to the unbalanced position before any connections are made to the RCA connectors

Trigger connectors

The SDA 2175 is equipped with TRIGGER IN and TRIGGER BYPASS sockets. These are ordinary 3.5 mm mono mini jack sockets.

When TRIGGER IN is left unconnected, the SDA 2175 will go into OPERATE mode when power is applied.

If there is a plug in the TRIGGER IN socket, the SDA 2175 standby mode is controlled by the voltage on the plug. With no voltage applied, the SDA 2175 will go into standby mode. If a DC voltage of 5-24V or a 50Hz AC voltage of 4-17Vrms is applied, the SDA 2175 will go into OPERATE mode.

TRIGGER BYPASS is for daisy-chaining a number of SDA 2175 and controlling them via the same signal. Connect the control signal to TRIGGER IN on the first SDA 2175 and connect its TRIGGER BYPASS to TRIGGER IN on the next unit, etc.

Cleaning and maintenance

Always unplug the unit from the electrical outlet before cleaning.

This unit does not require any regular maintenance except to keep its exterior clean. Simply wipe its exterior with a clean, soft cloth. A small amount of non-abrasive cleaner may be used on the cloth to remove any excessive dirt or fingerprints. Do not use abrasive cleaners.
