Sound Performance Lab 2489 Connectors, Inputs and outputs, Sub-D 25 connector pin configuration

Connectors

The SMC enclosure is EMC-safe and effectively shielded against HF interfer- ence. Nonetheless, you should carefully consider where you place the unit to avoid electrical disturbances. The SMC and all devices to be connected should be turned off before connections are made or change to avoid damage to your speakers and ears.

Inputs and outputs

INPUT A & INPUT C (Sub-D 25; analog)

This Sub-D connector provides balanced connections for INPUT A & INPUT C (INPUT A for six surround channels, INPUT C for two stereo channels). Use this connector for your multichannel source, i.e. DAW or DA converter.

SLAVE OUT (Sub-D 25; analog)

The SLAVE OUT provides a direct output of the INPUT A & INPUT C signals for connection to external equipment e.g. recorders, leaving the converter outputs free.

INPUT B & INPUT D (RCA)

Eight RCA input connectors are available for six surround channels and two stereo channels. INPUT B provides surround connection for SACD or DVD players, while INPUT D provides connection for stereo sources such as DAT or CD players.

Tip: If a recording device is connected to the SLAVE OUT, its outputs can be connected to INPUT B for tape monitoring purposes.

SURROUND and SPEAKER OUTPUTS (1/4“ TRS)

Eight balanced, 1/4" TRS connectors allow connection of a six-channel surround speaker set and a stereo speaker pair. Use standard mono 1/4” plugs for unbalanced connections.
