SINGLE-ENDED INPUTS
These RCA connectors accept single-ended inputs from preamplifiers with
single-ended (RCA) outputs. Both inverting and non-inverting inputs are
provided. Single-ended input signals are converted to balanced signals im-
mediately upon being received at the Nº33, and are handled as balanced
signals thereafter.

If your preamplifier does not support balanced connection to the power
amplifier, connect the single-ended output of your preamplifier to the non-
inverting RCA input on the Nº33. Repeat this process for the other Nº33(s)
in your system, being certain to be consistent throughout. To reduce the
chance of noise pickup at the (otherwise unterminated) inverting input,
short the inverting input of each amplifier by inserting the provided U-
shaped shorting strap between pins #1 and #3 of the XLR connector to re-
duce the chance of noise pickup at the (otherwise unterminated) input. (As
delivered from the factory, this shorting strap is already installed.)

Important!
If you use single-ended interconnection with the Nº33, you
must take care to use one input or the other (inverting or non-
inverting) consistently throughout your system. If you mix their
