IMPORTANT SAFETY INFORMATION Caution: Changes or modifications not expressly approved by the

manufacturer could void the user's authority to operate this device.

This equipment has been tested and found to comply with the limits
for a Class B digitial device, pursuant to part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio or television reception, which can be
determined by tuning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:

Re-orientate or re-locate the receiving antenna. Increase the
separation between the equipment and the receiver. Connect the
equipment into an outlet on a circuit different from that to which the
receiver is connected. Consult the dealer or an experienced radio/TV
technician for help.

Mains Supply: The mains operating voltage is shown on the rear
panel. If this voltage does not match the mains voltage in your area,
consult your dealer about converting the unit.

Install in accordance with the manufacturer's instructions.

Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding type
plug. A polarized plug has two blades with one wider than the other.
A grounding type plug has two blades and a third grounding prong.
The wider blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point where

they exit from the apparatus.

Use only attachments/accessories specified by the
manufacturer.

Use only with a cart, stand, tripod, bracket, or table

specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.

Unplug this apparatus during lightning storms or when unused for
long periods of time.

safely immediately after cutting it from the cord.

Connecting a Mains Plug

The wires in the mains lead are
coloured in accordance with the
code: Blue: NEUTRAL Brown: LIVE:
Green and Yellow: Earth. As these
colours may not correspond to the
coloured markings identifying the
terminals in your plug, proceed as
follows:

The BLUE wire must be connected to the terminal marked with the
letter N or coloured BLUE or BLACK. The BROWN wire must be
connected to the terminal marked with the letter L or coloured
BROWN or RED.

The GREEN & YELLOW wire must be connected to the terminal
marked with the letter E or coloured GREEN or GREEN & YELLOW or
marked with the Earth Symbol .

INSTALLATION

Place the unit on a stable rigid surface with at least 1m (3ft.) of free space above it. If you are
using a turntable, ensure that the tonearm/preamplifier combination is least 400 mm away
from the amplifier to minimise any hum conduction and ideally on a separate shelf. If you
have to use the turntable and the amplifier on the same surface, place the turntable to the
right of the amplifier to maximise the distance between the tonearm and the amplifier.

Do not use this amplifier in a confined space or an enclosed cabinet!

Avoid placing the amplifier in front of the loudspeakers to avoid vibrations from the speaker
drive units causing microphonics in the amplifier and degrading the sound.

If this is your first valve amplifier: please familiarise yourself with some important issues
surrounding the safe use of your amplifier.

Valves Get Hot

Valve power amplifiers generate a lot of heat even with no input so it is vital to ensure
adequate ventilation for your amplifier.

Although the protective cages over the valves get hot they are very unlikely to cause a burn.
For absolute safety the unit should be placed out of the reach of children and pets and away
from heat-sensitive objects.

Valve Amplifiers Work at High Voltages

Valves require a high voltage to function. Do not open the case. Also ensure that nothing is
poked, dropped or poured into the amplifier's case.

The environment should be dry and free from litter. Do not place magnetically or thermally
sensitive objects (i.e. credit cards or optical discs) close to the unit.

Valves are Microphonic

Because valves are constructed from fine wires and tiny metal parts they can pick up
external vibrations. If you place the power amplifier too close to the speakers, direct
sound at high volumes may vibrate the valves. 1 metre (3ft) to the side of each speaker
should be considered a sensible minimum.

Interconnects and Cables

The signal inputs to the amplifier are via RCA phono connectors. As valve equipment works
at high impedances, the phono interconnects from source unit should be well screened
and of a low-noise, low-capacitance construction. To minimise capacitance and other
effects, signal interconnects should be kept as short as possible.

Choose good quality loudspeaker cable designed for the purpose rather than general
purpose ‘zip’ or ‘bell’ wire. The cable should be of adequate gauge to maximise bass
performance. We do not recommend high inductance or capacitance cables as these can
degrade the sound when using a valve amplifier output stages.

Mains Earthing (Grounding)

This amplifier requires connection to an earthed (grounded) mains supply. In your sound
system, the amplifier should be the only device connected to mains ground to negate hum
induced by ground loops. For this reason we suggest that you avoid using interconnects
with separate ground wires. If any of your other equipment is grounded a “hum loop” may
arise. If this happens please consult your dealer for advice.
