Introduction

Congratulations on your purchase of a Mitchell & Johnson 800 series products.
The Mitchell & Johnson range has been painstakingly engineered in the United Kingdom
to offer class leading performance.

Users should read and follow this instruction manual, paying particular attention to the user
installation and safety advice sections.

This manual has been written to enable you to achieve the very best performance and maximum
listening pleasure from your investment.

We wish you many years of pleasurable listening.

With best regards, the Mitchell & Johnson team

Environmental Issues

Although Mitchell & Johnson electronics operate in standby mode as opposed to being fully
switched off, the power drain has been optimised to a negligible level. Contrary to popular audio­phile practice, we do not recommend leaving our power amplifiers permanently powered.

All Mitchell & Johnson amplifiers have been designed to attain full operational specifications and
sound quality within a few minutes of switch-on.

Mitchell & Johnson operates a 100% recycling program. All waste materials generated as part of
the manufacturing process at Mitchell & Johnson are recycled via a licensed specialist company.

WEEE Scheme

Disposal of Electronic Equipment in the European Union and other countries with
collection procedures:

The wheelie bin symbol on this product indicates that it shall not be treated as household waste. It
should be disposed of via a collection point for the recycling of electrical and electronic equip­ment.

Made in the UK

Your Mitchell & Johnson 800 series products were entirely designed and manufactured in the UK.

VERY IMPORTANT

Before connecting your new Mitchell & Johnson units to the rest of your system, please
ensure all required input/output cables are connected BEFORE inserting the mains power
lead and powering for the first time.

User installation and safety advice

Please ensure that the mains voltage of your new Mitchell & Johnson devices are correct
for your region. The setting is displayed on a label next to the mains power inlet.
The mains voltage setting is not user adjustable, therefore the product must be returned to
the dealer/manufacturer if any changes are required.

Ensure the mains supply is switched off at the wall socket, or unplugged before installing
or moving the units.

Do not use near water, for example do not place a potted plant on top of the units or allow
drinks to be placed near the units. If liquid is spilt in to the cabinet, remove the mains leads
from the wall immediately.

The products should then be returned to your dealer for safety testing before re-use.
Failure to do so may result in electric shock or even fire!

Do not use the units in damp conditions, for example, outside of the house.

In the event of an electrical storm, remove the mains power leads from the wall outlet.

Keep away from direct sunlight and other heat sources and ensure adequate ventilation
around the products to maintain proper cooling.

Units MUST NOT be stacked directly on top of each other.

Never attempt to open the cabinets. There are no user serviceable parts inside and doing
so will invalidate the manufacturers warranty.

Care should be taken to ensure there is no possibility of short circuit behind the units when
in use, for example, metal framed hi-fi units may be a hazard.
