introduction

The Myryad Z140 and Z160 have been
designed to offer a combination of high
quality sound reproduction and elegant
styling.

The Z140 Integrated Amplifier can accept up
to six line-level input sources, including two
tape recorders. Outputs are provided for one
pair of loudspeakers, for headphones and for
an auxiliary power amplifier. All functions –
input selection, volume and standby – can be
operated using the infra-red remote control
handset supplied.

The Z160 power amplifier can be used to
provide power for high quality stereo systems
when partnered by a suitable preamplifier or,
in partnership with a Z140 Integrated
Amplifier, to provide a very high performance
four channel solution for bi-amp capable
loudspeakers. Multiple Z160 amplifiers can
also be used to power a full-surround music
or Home Cinema sound system of the
highest quality.

The Z160 has a pair of unbalanced line inputs
plus directly linked line outputs, all on RCA
phono sockets.

The Z140 and Z160 are both Smart My-Link
compatible. When the Z140 is linked via the
“Smart My-Link” to other compatible Myryad
Z-Series, Cameo or M-Series products a
number of extra features become available
which make the system as a whole easier and
quicker to operate.

installation and
safety notes

The Z140 and Z160 both generate a modest
amount of heat and thus require ventilation.
Do not place either on a rug or other soft
surface into which they could sink,
obstructing the air inlets in the underside. Do
not allow papers or cloth to obstruct the
ventilation grille in the top cover. Neither
amplifier should be placed in a built-in
installation such as a bookcase or rack unless
proper ventilation is provided. If a number of
Z-Series units are stacked on top of one
another, the amplifier(s) should be placed on
top.

CAUTION:TO PREVENT A FIRE OR SHOCK
HAZARD, DO NOT PERMIT ANY OF THESE
PRODUCTS TO BECOME WET. IF LIQUID IS
ACCIDENTALLY SPILLED ON ONE, 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
IT AGAIN. IF THE LIQUID IS ANYTHING BUT
WATER AND/OR ALCOHOL, A QUALIFIED
SERVICE TECHNICIAN SHOULD EXAMINE THE
UNIT BEFORE IT IS USED AGAIN.

DO NOT PLACE NAKED FLAMES SUCH AS
LIGHTED CANDLES ON THIS PRODUCT.

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

z-series system
operation with
smart my-link

When used as a linked system (e.g Integrated
Amplifier plus Power Amplifier, CD Player,
DVD Player and Tuner), Z-Series products
have a number of extra features that make the
system as a whole easier and quicker to use
than a normal hi-fi. These include:

Start-on-Play (CD, DVD):

Press play on the CD or DVD Player (or the
relevant remote control) and the player and
Amplifier will switch out of standby (if
necessary) and play the disc. The Amplifier
will automatically select the appropriate
source.

Start-on-Open (CD, DVD):

With the units in standby, press open/close
on the player. Both the player and amplifier
will switch out of standby and the player’s
drawer will open. The Amplifier will
automatically select the appropriate source.

Intelligent Input Selection (Amplifier):

Press a source select button on the remote
control and the system will awaken (if in
standby) only the Amplifier and the selected
source.

Mute/Pause Control (Amplifier/CD or DVD):

When using the CD or DVD Player, selecting
mute from the remote control will mute the
Amplifier and pause the disc. When the
amplifier mute is cancelled, the disc will
continue playing.

Power-Saving Mode (Amplifier):

The Amplifier will switch the CD Player, DVD
Player or Tuner into standby if any source
remains unused for more than ten minutes.

Automatic Switch-On (CD, DVD, Tuner):

If the standby button on the Tuner, CD or
DVD player is pressed, the Amplifier will also
awaken and select the correct source.

trouble-shooting
guide

Possible solutions to some of the most
common problems.

No sound:

• Power turned off or system in standby
mode. Check that the green STANDBY LED
in the amplifier is illuminated and that the
relevant source component is also active.

• An inoperative input has been selected
(e.g. CD input with no CD playing).

• An input has been selected with no
source connected.

• Protection relay has operated because of a
short circuit loudspeaker wire or amplifier
overheating. Carefully check all wiring after

switching the amplifier POWER OFF to
allow it to cool.

• UK version only: The fuse in the mains plug
has failed. Check and replace if necessary.

Sound in one channel only:

• Loudspeaker cable pulled loose. Check
all connections, both at the loudspeakers
and amplifier.

• Interconnect cable pulled loose or making
poor contact. Check and, if necessar y,
un-plug and re-plug all relevant cables.

Loud buzz or hum:

• Interconnect cable pulled partially out

of its socket.

• Defective interconnect cable.
