Introduction

t from a phono cartridge by installing a Myryad Phono Cartridge

The Myryad MI 240 Stereo Integrated Amplifier has been designed to deliver a combination of high quality sound
reproduction and elegant styling.

The amplifier can accept up to eight line-level input sources, including two tape recorders. Outputs are provided for one
pair of loudspeakers and for headphones. All functions can be operated using the infra-red remote control handset
supplied. This remote can also control Myryad CD players and Tuners and up to six other products – either using its
built-in code library or by “learning” from another remote.

The MI 240 offers a range of expansion possibilities:

• The AUX. input can be converted to accept the outpu
Preamp Module (either MM for Moving Magnet or “high-output” moving coils, or MC for “low-output” moving coils).

• A low-level "Bi-amp" output is provided to feed the Myryad MA 240 Power Amplifier, allowing bi-amplified drive of
suitable loudspeakers.

• The My-Link input/output can be coupled to other Myryad products which can then be remote-controlled via the MI­240's infra-red receiver or vice-versa.

• When linked via the "Smart My-Link" to other compatible Myryad M-Series or Cameo products a number of other
features become available which make the system as a whole easier and quicker to operate.

Accessories - Your MI 240 is supplied complete with the following accessories:

• Separate mains power cord to suit country of sale.

• Myryad Audio-Video Learning Remote Control Handset.

• Four AAA batteries for handset.

• Home Theater Master SL-9000 Operating Manual.

Safety and installation notes

This amplifier generates a modest amount of heat and thus requires ventilation. Do not place it on a rug or other soft
surface into which it could sink, obstructing the air inlets in its underside. Do not allow papers or cloth to obstruct the
ventilation grille in the top cover. The amplifier should not be installed in a built-in situation such as a bookcase or rack
unless proper ventilation is provided

CAUTION: To prevent a fire or shock hazard, do not permit this product to become wet. If liquid is accidentally
spilled on it, immediately shut off its power at the wall socket and unplug the AC power cord. Allow sufficient time for
complete evaporation to occur before operating the amplifier again. If the liquid is anything but water and/or alcohol, a
qualified service technician should examine the amplifier before it is used again.

Do not remove the cover, or attempt to modify or repair the amplifier yourself. Refer all servicing to a qualified
technician.

Setting up your system – Rear panel connections

Link bus is that all linked units will switch into or out of standby mode when the MI 240’s front panel STANDBY

1. POWER inlet

Before making any connection, check that the mains voltage setting printed on the rear panel is the same as your local
mains supply.

Plug the female (socket) end of the power cord into the power inlet on the rear of the amplifier. Plug the male (plug) end
of the cord into a "live" wall socket or a suitable heavy duty extension cable.

UK version: The mains plug is supplied fitted with a 5A fuse. It should only be replaced with a fuse of the same rating (5A) which complies with
BS1362.

2. POWER switch

Press one side of this rocker switch (the side nearer the edge of the rear panel) to switch the amplifier ON and the other
side (towards the speaker terminals) to switch it OFF. When the POWER switch is in the OFF position all power is
disconnected from the amplifier. In this condition the amplifier cannot be powered up from the front panel or the remote
control. When the POWER switch is in the ON position (and the power cord correctly inserted and plugged into a live
wall socket) the amplifier will power up in standby mode (see Front Panel Controls, STANDBY, below).

It is recommended that the POWER switch is turned OFF if the amplifier is not going to be used for an extended period
of time.

3. MY-LINK input/output

When the MI 240 is used in a system with other Myryad products (e.g. M-Series or Cameo), all may be joined together
via the My-Link. The My-Link is a communications bus that allows all the linked components to operate together as a
system and distributes the remote commands received by any one to each of the others. The simplest function provided
by the My­button or remote control POWER key is pressed.

Use a short RCA-to-RCA (phono-to-phono) interconnect cable to connect from the MY-LINK OUT socket on the MI 240
to the MY-LINK IN socket on the next unit (e.g. CD player). A second cable may then be run from the MY-LINK OUT
socket of that unit to the MY-LINK IN socket on the next and so on in “daisy-chain” fashion. Further compatible Myryad
products can be linked in the same way. Inexpensive interconnects may be used as the My-Link bus carries only control
signals, not audio, so these cables have no effect on sound quality. Suitable interconnects are supplied with Myryad CD
players, Tuners and Power Amplifiers.

When Myryad products equipped with “Smart My-Link” are connected to the MI 240 via the My-Link, many more
powerful system features are available (see page 8).

4. LOUDSPEAKER outputs

The loudspeaker outputs are capable of driving all loudspeakers with rated impedances in the range 4 Ω to 16 Ω. The
loudspeaker terminals are high-current binding-posts, coded red or black. The terminals on the left side of the amplifier
(viewed from the front) and marked "L" should be wired to the left hand loudspeaker. Those on the right, marked "R",
should be wired to the right hand loudspeaker.

CAUTION: The red terminals are marked with a hazard symbol to indicate that they can be live. Read all the
loudspeaker wiring instructions carefully. It is recommended that ready-made leads be used where possible.

For correct stereo imaging it is important that the two loudspeakers are wired "in phase". To ensure correct phasing wire
the black (-) terminal on the amplifier to the black or "-" terminal on the loudspeaker. The red (+) terminal on the
amplifier should be wired to the red or "+" terminal on the loudspeaker.

The loudspeakers should be positioned as recommended by the loudspeaker manufacturer. The two loudspeakers
should always be placed at equal distances from the main listening position and usually spaced a similar distance apart.
It is generally best to keep the loudspeakers away from room corners and many loudspeakers work best away from all
walls.

5. BI-AMP output

Many loudspeakers today are made so that the bass and treble sections can be separated and fed from two sets of
speaker cables. This is known as "bi-wiring" and can yield a significant improvement in sound quality. A further sound
quality gain may be made by "bi-amplifying" the loudspeaker - using two separate power amplifiers to drive the bass and
treble sections.

The MI 240 makes provision for this with its "BI-AMP" output, which can be used to feed a separate MA 240 Power
Amplifier. The MI 240 loudspeaker outputs would be connected, for example, to the bass sections of the loudspeakers
(left and right) while the MA 240 drives the treble. This mode of operation is described in more detail in the MA 240
Owner's Manual and also on the Myryad website www.myryad.co.uk.

6. LINE DIRECT input

The LINE DIRECT input provides the shortest, cleanest signal path through the amplifier and will deliver the best sound
quality of all of the MI 240’s line inputs. The audio output from any high quality line level source may be connected to this
input. It is not possible to make a recording from a source connected to the LINE DIRECT input using the MI 240’s
TAPE or CD-R REC outputs.

7. TAPE input/output

These connectors are suited to any type of tape recorder, including high-quality "3-head" types which allow you to
monitor the signal off the tape whilst it is being recorded. Connect a stereo cable from the TAPE REC output sockets of
the amplifier to the LINE IN or RECORD IN sockets on your tape deck. Connect a second stereo cable from the TAPE
PLAY input sockets of the amplifier to the LINE OUT or PLAY OUT sockets on your tape deck.

Any source selected for listening on the MI 240 (apart from LINE DIRECT) will automatically be fed to the TAPE REC
output sockets for recording. If the CD-R input is selected then tape copies may be made from CD-R to TAPE. It is NOT
possible to copy from TAPE to CD-R.

8. CD-R input/output

These connectors are suited to the analogue outputs/inputs of a digital recorder (e.g. CD-R or Mini-Disc) or any type of
analogue tape recorder, but "off-tape" monitoring is not possible using the CD-R input. The wiring from CD-R to your
tape deck is identical to the TAPE wiring described above.

Any source selected for listening (except TAPE or LINE DIRECT) will automatically be fed to the CD-R REC output
sockets for recording. It is NOT possible to record from TAPE to CD-R.

9. CD input

Connect the audio output cables from a CD player to these sockets. NOTE: this input is for an audio signal, not for
the digital output from your player. If you do not have a CD player then any other line level source may be connected

to this input.

10. TUNER input

Connect the audio output cables from a radio tuner to these sockets. If you do not have a tuner then any other line level
source may be connected to this input.

11. TV input

Connect the audio signal output cables from a video-related source such as a TV set or VCR to these sockets.
Alternatively any other line level source may be connected to this input.
