INSTALLATION

Introduction

Congratulations on the purchase of the new M6 500i integrated amplifier. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction.

The unit features a finely tuned and tweaked preamplifier, for smooth sound coupled with low noise and virtually no distortion.

The power amplifier consists of two monoblock amplifiers with separate supplies for the absolute best in separation and imaging. Generously rated, they are enough to drive even the most demanding loudspeakers with ease. Low distortion and very quiet they will deliver all music types exactly as the artist originally intended.

The resultant performance achieved by this unit is among the best in the world. It has excellent signal to noise ratio, low distortion, wide bandwidth and dynamic range, with extraordinary resolution and fine detail.

Cleaning

Before cleaning the unit, switch off power at the mains switch and remove the mains plug from the wall socket.

Clean the cabinet and remote control unit using a moist cloth. Using solvents, white spirit or thinners is not advised, as they could damage the surface finish.

Installation

Position the M6 500i on a stable, horizontal surface where there is no risk of it being knocked, or subjected to vibration such as from loudspeakers.

Important note:

In normal operation, the unit dissipates a quantity of power at all times, and it is important that it is adequately ventilated. The top and bottom are perforated to allow the smooth flow of heat through the unit. It is therefore not recommended that the unit is enclosed in a cabinet or placed where the ventilation holes are impeded as this could result in excessive heat build-up.

The M6 500i must be protected from humidity – if the unit is moved from a cold place to a warm room, leave the unit for an hour or so to allow sufficient time for the moisture to evaporate.

Power Connections

The M6 500i is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the unit (see page 7)

Audio Connections

RCA Inputs: Connect all RCA single-ended sources to relevant analogue inputs (see page 7 for more information). Use good quality fully connected (signal and ground) coaxial phono cables for all RCA signal connections.

XLR Inputs: Connect any XLR balanced source to balanced analogue input (see page 7 for more information). Use good quality fully balanced and connected (signals and ground) XLR cables for all XLR signal connections.

Outputs: Connect loudspeakers to the terminals on the back panel marked as LEFT and RIGHT SPEAKER

outputs. For most normal passive speakers this bridged amplifier behaves as any other, however:-

NOTE: this amplifier’s RED and BLACK speaker terminals carry speaker voltages and currents.

Do not use grounded speakers e.g. some electrostatics or amplified subwoofer “speaker” inputs, as this could short one half of the amplifier to ground and cause potential damage. Check with dealer or speaker manufacturer for advice. Take great care when bi-wiring or bi-amping to not cause inadvertent short circuits.

The TAPE output allows loop through of analogue signals for example, to pass on to recorder or monitor. It is also the ideal output to connect our headphone amps into.

The PRE-OUToutput allows analogue signals controlled by the volume, to pass on to a second amplifier. This is useful for bi-amping, and recommended for amplified subwoofer connection, if required.
