AC MAINS SUPPLY
Your M2 Integrated Amplifier is set to operate from a fixed supply voltage which is marked on a label next to
the mains input plug. Before connecting the mains lead please check that your mains supply corresponds to
this label as below:
230V Products ........................................ Voltage Range:
115V Products ........................................ Voltage Range:
100V Products ........................................ Voltage Range:
The mains lead supplied with this product has an IEC mains socket which plugs into the IEC connector on the
unit's rear panel. The other end is normally attached to the appropriate mains plug for your country. In the UK
this is the standard UK10A plug.
This plug should ordinarily not be removed from the lead. If you do remove it, please dispose of it safely so
that it cannot be plugged into a mains socket whilst in a potentially dangerous condition. We suggest that you
obtain from your dealer a complete replacement lead.
Should you move to another area where either the mains voltage or the mains plugs are different from those
as supplied with your Integrated Amplifier, please contact the appointed ROKSAN distributor for assistance.
Please observe correct mains polarity at all times.
The Integrated Amplifier mains fuses are located on the rear panel next to the IEC mains connector. These
must only be replaced by the fuse type and rating as described on the fuse rating label on the rear panel of
the unit.
If the equipment is likely to be unused for some time, unplug it from the mains supply.

Please refer to front & rear panel view on Page 2. The moulded IEC connector of the supplied
mains lead should be plugged into the socket (14) on the rear of the unit first and then plugged
into the mains supply. The Mains power switch (12) is on the left front underside of the
Integrated Amplifier. This switch can be left on; if however the amplifier is likely to be
unattended for a long period, switch it off and unplug the mains lead from the wall.

Signal Input connections:
There are five Inputs (1 – 5) on your M2 Integrated Amplifier in addition to the Tape Input (6). All
these inputs are line level inputs and will accept virtually all currently available source
components.
All the inputs use gold plated RCA Phono Connectors
to gold plated Balanced XLR)
– Right Channel – Red; Left Channel – Black or White.
Also in accordance with standard practice, the Upper row of Phono Sockets carries the Left
Channel and the Lower carries the Right Channel.
The Input Sockets are labelled with their legends upside down as well as the normal way round
to assist you should you be connecting an input from a position in front of and above the
amplifier.
Phono Input Connections:
As your M2 Integrated Amplifier is a line level unit you cannot connect a phono cartridge directly
to it but will need a dedicated phono preamplifier. The ROKSAN range of Phono
Amplifiers accept conventional moving coil and moving magnet cartridges and have custom
equalisation for the outstanding ROKSAN Shiraz cartridge. For a demonstration of ROKSAN
state of the art turntable reproduction contact your authorised retailer.
IMPORTANT NOTE: For optimum performance it is recommended to use high quality inter-
connect cables such as ROKSAN HDC-02A high definition analogue cable.

The right and left loudspeakers are connected to the amplifier via the rear panel binding posts
(11) and (12) respectively. There are two basic types of cable –
n e l V i e w
n e l V i e w
 Figure 8 cable has two insulated conductors which lie parallel, either side by side, or
spaced by insulation.
10 11
 Overall sheathed cable has both conductors insulated and enclosed in an overall plastic
sheath.
Carefully remove any overall sheath or split the figure 8 cable to a depth of about 75mm (3").
Carefully strip the insulation on each wire to a depth of about 12mm (1/2") exposing the bare
core. If the conductor is stranded, twist the strands together on each conductor.
Unscrew the binding post. There is a cross-hole about 5mm from the panel end
of the binding post. Insert the bared conductor through the hole and tighten the
binding post securely making sure that there are no loose strands or bare ends
protruding through the post.
Carefully observe polarity ensuring that the RED (+) speaker terminal is
connected to the RED (+) amplifier terminal and the BLACK (-) speaker terminal
to the BLACK (-) amplifier terminal.
When both left and right channels are connected to their respective speakers the
amplifier is ready for use.
IMPORTANT NOTE: For optimum performance it is recommended to use high quality cables
such as ROKSAN HDC-02S high definition Loudspeaker Cable. Many speaker cables such as
the ROKSAN HDC-02S are directional. Please observe this directionality. DO NOT use speaker
cable with conductor size less than 16 AWG (1.6mm Diameter). The Binding posts accept
n n e e l l V V i i e e w w
conductor sizes up to 12 AWG.

If the Loudspeakers utilise more than one drive unit with individual input terminals, for example
a Tweeter and a Woofer, then the loudspeaker performance will benefit from Bi-Amping.
Dedicating one amplifier to the Tweeter and another to the Woofer isolates them from each
other reducing distortion and increasing reserved power. Speakers work far better with most
amplifiers when Multi-Amped than using one yet more powerful amplifier. Note: Bi-Wiring
reduces the impedance seen by the Woofer and the Tweeter and is a first step towards Bi-

The Mains power switch (12) is on the left front underside of the Integrated Amplifier. This
switch should be left ON for normal operation. If unattended for a long period, the Mains power
should be switched OFF and the lead disconnected from the power supply.
When switched ON your M2 Integrated Amplifier runs a self-test and the amplifier enters
WARM-UP mode and the MODE indicator light (3) will glow GREEN. The amplifier is now ready
for use.
You can activate your M2 Integrated Amplifier in two ways:
1 Press the MODE button (2) once.
2 Rotate the INPUT selector (1) in either direction by one step.
NOTE: Only the Power Button on the remote handset activates/de-activates the
amplifier.
Please note the remote handset MODE button only activates/de-activates -20dB
Mute (see below)
Once the M2 is On the MODE indicator light (3) will glow RED. The amplifier will automatically
select the CD input and the CD input indicator light (4) will glow.
U U S S I I N N G G T T H H E E C C O O N N T T R R O O L L S S
The MODE button on the Front Panel has the following functions:
It activates the amplifier from Warm-up.

 Pressing the MODE button once with the amplifier activated will mute the volume
level by 20dB. The MODE indicator light will glow ORANGE. The amplifier remains
fully functional in this mode. Another single press un-mutes the amplifier and the
MODE indicator light will revert to RED.
 With the amplifier activated, a sustained press on the MODE button reverts the
amplifier to Warm-up, all the input indicator lights will be extinguished and the MODE
indicator light will glow GREEN.
NOTE: When you bring the M2 out of WARM-UP having switched it ON at the Mains, the
input selector will default to CD (as described previously).
When, however, the M2 has been put into Warm-up from the MODE button on the
front panel, bringing it out of Warm-up will restore previously selected input, tape and
mute values. Bringing the M2 out of Warm-up by moving the INPUT Selector one step
in either direction also leaves these amplifier settings unaffected.
The INPUT Selector is an endless rotary switch that moves round one click at a time. It
connects each signal source to the amplifier by rotating through the Inputs with the exception of
TAPE. Rotating the Selector continuously clockwise will select inputs in this sequence:
CD – TUNER – VIDEO – LINE1 – LINE2 – CD - ...
Rotating the Selector anti-clockwise reverses the sequence.
Whenever an input is selected the appropriate indicator light will glow.
The VOLUME Control is a precision device. It follows a logarithmic law so that its response
approximates that of the human ear. There is an illuminated indicator on the volume control to
clearly show the appropriate volume setting.
