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 Five Channel Amplifier has both balanced
(XLR) and single-ended (RCA) inputs, with a small switch between the two
connectors to select between them. Using these switches, select the appro-
priate input for each channel, given your interconnecting cables and pream-
plifier/controller’s capabilities.

3

CONNECT YOUR PREAMP TO THE AMPLIFIER

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 AMPLIFIER

Connect speaker wire from the amplifier 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 unstable.)

5

CONNECT THE AC CORD TO THE AMPLIFIER 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.

6

TURN ON THE AMPLIFIER BY PRESSING POWER, THEN STANDBY

Press the latching 

power 

button on the front panel of the amplifier (small,

near the bottom) to connect the amplifier to the AC mains. The amplifier
will initially power up in standby mode. After five seconds (to let the power
supply charge up), pressing the large silver 

standby 

button will bring the

amplifier out of standby into its normal, fully operational mode.
