A Quick Start

We recognize that many people are understandably eager to begin listening to
their new components, and that reading the manual is often done (if at all) at a
later time—perhaps while listening to music through the new product itself. We
strongly recommend that you read this manual thoroughly.

Fortunately, we can help you get some music up and running on your system
quickly, so that you may begin enjoying your new amplifier while reading more
about it. The goal here is simply to make some music as quickly as possible.

The following procedure assumes that the rest of your system is already con-
nected (e.g., source components to preamplifier).

1

TURN DOWN THE VOLUME ON YOUR PREAMPLIFIER

Turning the volume on the preamp all the way down minimizes the oppor-
tunity for unpleasant surprises when first powering up your new amplifier.
It does not need to be turned off—merely turned down.

2

SELECT “XLR” OR “RCA” WITH THE “INPUT SELECT” SWITCHES

Each channel of the Proceed AMP 2 and AMP 3 has both balanced (XLR)
and single-ended (RCA) inputs, with a small switch between the two con-
nectors to select between them. Using these switches, select the appropriate
input for each channel, given your interconnecting cables and preamplifier’s
capabilities.

3

CONNECT YOUR PREAMP TO THE AMP

Having selected the appropriate inputs in Step 2, now connect the outputs
of your preamplifier to the corresponding inputs on the power amplifier.

4

CONNECT YOUR SPEAKERS TO THE AMP

Each channel of the Proceed AMP 2 and AMP 3 is supplied with two sets
of  binding posts to facilitate bi-wiring. Using either the top or the bottom
set of red and black binding posts, connect speaker wire from the AMP to
your loudspeakers. Be sure to maintain consistency in polarity, e.g., the red
post on the amplifier to the red connector on the speaker, and likewise
black to black. (Getting the wires mixed up won’t damage anything, but the
sound will be lacking in bass and the imaging will be quite poor and un-
stable.)

5

CONNECT THE AC CORD TO THE AMP AND TO YOUR AC OUTLET

The AC receptacle for the power cord is located on the right side of the
rear panel, as seen from the front. The AMP will initially power up in
standby mode.
