Caution!

Using single-ended preamplifiers

Using single-ended amplifiers

During calibration, the Left input (in the top left corner as seen from behind the unit) is also used by your installer for connecting the output of the calibrated microphone that measures the room’s response.

Do not connect the calibrated microphone to the Left input input of the SC-1 until instructed to do so a part of the MultEQ® Pro software application.

Doing so before completing the Product Selection screen as part of the MultEQ Pro application (see Product Selection, page 31) will cause microphone feedback at levels that could damage the speakers.

If your preamplifier/processor does not have balanced outputs, the adapter used to convert from balanced to single-ended should tie Pin 1 and Pin 3 (the inverted signal) together. This can easily be checked with an ohmme- ter: the impedance between Pin 1 and Pin 3 should approach zero. Note that the most suitable adapter on the input side of the SC-1 is different than the appropriate adapter on the output side, due to the SC-1’s high input impedance. Should you need them, properly wired adapters are available from Wisdom Audio for a nominal charge.

27 Channel High (Planar) Output

These seven balanced audio outputs carry the room-corrected “high pass” portion of the audio spectrum, and must be connected to the amplifiers that drive the planar magnetic panels.

The pin assignments of this XLR-type male output connector are:

Pin 1: Chassis ground

12 Pin 2: Signal + (non-inverting)

3Pin 3: Signal – (inverting)

Connector ground lug: chassis ground

These pin assignments are consistent with the standards adopted by the Audio Engineering Society. Refer to the operating manual of your power amplifier to verify that the pin assignments of its input connectors cor- respond to your Wisdom Audio SC-1. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin, in order to preserve the polarity of the musical signal.

If your power amplifier does not have balanced inputs, the adapter used to convert from balanced to single-ended must “float” Pin 3 (the inverted signal). This can easily be checked with an ohmmeter: the impedance be- tween Pin 3 and either the center pin or the shield skirt on the RCA should be infinite. Tying the output of Pin 3 to ground (as many adapters do) will compromise the performance of the SC-1, due to its low output imped- ance. Note that the most suitable adapter on the input side of the SC-1 is different than the appropriate adapter on the output side, due to the SC-1’s low output impedance. Should you need them, properly wired adapters are available from Wisdom Audio for a nominal charge.
