s80 Integrated Amplifier

Owner's Manual

r e s o l u t i o n

From all of us at Resolution Audio, thank you for choosing the Opus 21 s80 amplifier. We went to great lengths
to design and produce an integrated amplifier that offers musical pleasure and superior performance.

Unpacking

After unpacking your Opus 21 s80 amplifier, inspect it for any shipping damage and contact us immediately
if any is found. Do not plug it into the power supply if you find any shipping damage.

Please keep all packing materials for future transport of your amplifier. Shipping the Opus 21 in anything
other than its original crate may result in damage that is not covered by warranty. If you require
a replacement crate or packing materials, please contact Resolution Audio.

Should you need to repack the unit, be certain to place the amplifier between the supplied foam sheets,
with the accessory box on top.

The accessory box contains the following items:
Opus PowerLink cable
(2) Toroidal power transformers for installation in your Opus 21 Power Centre
Hardware to install the transformers
Replacement fuse
An integrated circuit to update the software in your Opus 21 Power Centre, if necessary

Installation

The s80 amplfier must be used in conjunction with your Opus 21 cd player and Power Centre.

If the toroidal power transformers have not yet been installed in your Power Centre, contact your dealer or
Resolution Audio directly for assistance. The new fuse should also be installed in the power entry module
located on the rear of the Power Centre.

The s80 amplifier must be located directly beneath your Opus 21 source components.

First, remove the dust cover from the connector located on the bottom of your Opus 21 cd player. Next, position
the cd player directly on top of the s80, ensuring the connectors are aligned. Press the connectors firmly
together to secure the connection.

Locate the Opus 21 cd+s80 and Power Centre on your shelf.

Be sure to leave space around the s80. It should be placed on a firm surface to allow adequate ventilation.
We recommend that the Power Centre be placed on a separate shelf for optimum performance.

Turn off any associated components prior to connecting the Opus 21.

This minimizes the chance of momentary electrical surges disturbing your system.

Connect the OpusLink interconnect to both the cd player and Power Centre.

Note that the cable can only be installed in one direction. Secure the connectors by hand-tightening the
integral screws.

Connect the Opus PowerLink cable to both the s80 and Power Centre.

Note that the cable can only be installed in one direction.

Connect your speaker cables to the s80 using either spade lugs or banana jacks.

The optional binding posts work best with spade lugs. Ensure proper polarity, which is indicated on the top of
the connector. If your speaker is fitted with a separate ground connection, it may be attached to the center
(yellow) banana jack, which is returned to the amplifier star-ground.

With the power switch in the OFF position, attach the power cord and connect it to your outlet.

The OFF position is selected when the O symbol on the switch is depressed.

Turn on the main power switch.

The ON position is selected when the | symbol on the switch is depressed. The Opus 21 will take a few seconds
to initialize and read the disc if present. The s80 selects the cd as the default input.

Turn on the rest of your system.

It is a good habit to turn the amplifier on last, and off first, to prevent surges and transients from reaching
your loudspeakers.

Insert a disc and press PLAY, or select another input.

The s80 amplifier will automatically select the cd input when a disc is played. Analog inputs may be selected
from the remote control or directly from the front panel. The digital input of the cd player is accessed only from
the remote control.

The Opus 21 is designed to remain powered continuously. In standby mode, the display is turned off and the
output is muted, but all of the circuitry remains powered. The output modulator is also disabled in standby.
If you do not intend to use the player for an extended period of time, the power may be removed via the
power switch in the rear. When power is re-applied, the Opus 21 will warm up and sound its best in about 1 hour.
