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.
