I have 2 NAD 2200 power amps, set up for bridge mono mode. These
amplifiers are designed to operate in this mode, but are somewhat
short on connection instructions. Each amplifier is connected to its
own speaker using the 2 speaker terminals indicated on the back of the
amp for bridged mono mode. =A0Speaker to amp connections i think should
look like this:

Left speaker + ----------------NAD Amp #1 bridged +
Left speaker - ----------------NAD Amp #1 bridged -

Right speaker + ------------NAD Amp #2 bridged +
RIght speaker - -------------NAD Amp #2 bridged -

**This is incorrect. I suggest you refer to your instruction manual. When=
in
bridge mode, the outputs are taken from the +ve terminals only. The -ve
terminals are not connected.



Connection to the preamp is less clear. My NAD 1135 preamplifier just
has a "normal" and a "high" =A0Pre-Out =A0L and R. I assume i'd use the
"normal" L and R ouputs like this:

Preamp Out
L--------------Y cable-----------------Poweramp #1 input L
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0\-----------------Po=
weramp #2 input L

Preamp Out
R-------------Y cable----------------Poweramp #1 input R
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 \----------------Powera=
mp #2 input R

Is this right? Thanks.

**You should use the input terminal labelled 'mono'. One connection per
channel.

there are 4 inputs on the back of the NAD 2200 poweramplfier. "LAB"
and "NORMAL" L and R. Neither says mono. There is a switch for bridge
mono which of course i have selected. I thought i'd need to feed both
the L and the R sides of the poweramp the same output from the preamp.
I think what you're suggesting is feeding a single poweramp input
should suffice.
