Rear panel

Disconnect all associated equipment from the AC mains BEFORE making any signal connections and applying power to the Nº38.

Note: All left-channel inputs and outputs are on the left of the rear panel as seen from the front, and all right-channel inputs and outputs are on the right of the rear panel as seen from the front. This design minimizes any possible confusion when changing connections once the unit is installed, while maximizing channel separation in this dual monaural preamplifier.

1BALANCED MAIN OUTPUTS

If your power amplifier is equipped with balanced (sometimes called “differential”) inputs, it is best to use these balanced outputs on your Nº38. A balanced signal from preamplifier to power amplifier will offer the highest possible performance with the best immunity from common-mode noise, such as radio frequency interference (RFI). The balanced output signal is made available by way of precision male XLR connectors (requiring female XLRs on the preamplifier end of the interconnecting cable).

The pin assignments of these XLR-type male outputs are:

Pin 1: Signal ground

1 2 Pin 2: Signal + (non-inverting)

3Pin 3: Signal – (inverting)

Connector ground lug: chassis ground

Refer to your power amplifier’s operating manual to verify that the pin assignments of its input connectors correspond to the Nº38. If not, wire the cable so that the appropriate output pin connects to the equivalent input pin.

Connect the right-channel and left-channel Balanced Main outputs of the Nº38 to the appropriate balanced inputs of the power amplifier.
