1. Input Select Switch.

Each SST channel gives the user the option of switching between either balanced input or single ended input.

2. Balanced Input connector. ( Imp. 20k )

This input connector accepts standard ‘XLR’ or 1/4” TRS .

Use quality, 100% shielded cables with gold plated connectors.

3. Single Ended Input. ( Un-balanced input ) ( Imp. 50k )

This input connector accepts standard ‘RCA’ or ‘Phono’ connectors.

Use quality, 100% shielded cables with gold plated connectors.

Balanced input Vs Single ended input:

The balanced input requires a balanced pre-amp source. Balanced systems provide noise rejection from external electrical interference, so cable length can be very long ( 50m or longer ).

The single ended or unbalanced input is provided for pre-amps without balanced output. Single-ended cables should be kept to 20’ (7m) or less. In general never use longer cables than necessary, never coil excess cable length, and keep signal wires away from AC power or speaker cables.

4. Input Sensitivity (Gain) Switch.

The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference.

The 1v setting is used when the source is single-ended, or from a transformer coupled balanced source. This is the home theatre setting for single ended or un-balanced operation.

The 1v setting provides the most amplifier gain - 29 dB. (1v in = 100w @ 8 ohms.) (noise -110 dB)

The 2v setting is used when the sources output is actively Balanced.

This is the home theatre setting for balanced operation Or use this setting with any systems where the volume control rotation is limited to the bottom half of the control or less.

The 2v setting provides an amplifier gain - 23 dB. ( 2v in = 100w @ 8 ohms.) ( noise -113 dB )

The noise is referenced in dB below rated output. Different input configurations result in slightly different noise readings. The above noise ratings represent minimum readings, actual readings may be better.

5. Level Control. (pro models only)

The level control will attenuate the input signal level from 0dB through -14dB.
