antenna
The wire antenna supplied with the MT 100
may provide adequate reception of strong FM
signals. However, such an antenna is not very
efficient at rejecting “multipath” and other
forms of FM interference. Nor can it easily be
rotated to optimize its pickup pattern for best
reception of stations from different directions.
In most cases you will greatly improve recep-
tion by using a better antenna.
The best choice is a directional FM-only
antenna, mounted as high above ground as
is practical. The antenna should be mounted
externally for best reception, but loft
mounting is a simpler alternative which is
satisfactory in many locations when adequate
loft space is available. The type of antenna
necessary will depend upon both your
distance from the transmitter and the
local geography (e.g. intervening hills or
large buildings).
It is also most important to pay attention to
the quality of the coaxial cable used for the
downlead from the antenna to your tuner.
Avoid joins along the length of the cable and
ensure that the exposed end at the antenna is
properly weatherproofed against ingress of
moisture. All cables lose some signal along
their length and it is false economy to use
cheap cable of unknown quality. Always
specify the best “low loss” coaxial cable
The above notes are for guidance only.
It will usually be best to consult a local
specialist aerial/antenna contractor who will
have knowledge of local reception conditions.
Your Myryad dealer may also be able to
offer advice.
trouble-shooting
guide
some of the most common problems
No sound:
• Power turned off or system in standby
mode. Check that the blue LED in the
STANDBY button is illuminated.
• UK version only: The fuse in the mains
plug has failed. Check and replace
if necessary.
Sound in one channel only:
• Interconnect cable pulled loose or making
poor contact. Check and, if necessary, un-
plug and re-plug all cables.
Loud buzz or hum:
• Interconnect cable pulled partially out
of its socket.
• Defective interconnect cable.
Hiss that gets worse with stereo reception
• Antenna connector loose. Un-plug and
re-plug connector and check cable.
• Weak antenna signal. Move wire antenna to
optimize reception. If not adequate, install
a loft or external antenna.
• If all else fails, switch to MONO reception.
Stereo indicator fails to light during a
stereo broadcast
• Another possible effect of a very weak
signal. Attend to the antenna system as
described above.
Distorted reception
• “Multipath” reception. Rotate antenna to
find the orientation that provides the best
reception. Raise the height of the antenna.
If all else fails, switch to MONO reception.

simply switch to Manual mode after tuning.
A Signal Strength reading of 5 or below
indicates that improved sound quality might
be achieved by improving the antenna system.
Manual Display Mode (Figure 3)
9Search tuning mode
Press the SEARCH button to enter Search
Tuning mode. The display shows the tuned
frequency, together with “SCn” where “n” is
the signal strength (1 to 9). When the tuning
knob is turned one step clockwise the MT 100
will commence searching for FM stations at
frequencies higher than the start point and
the display will change to “SCH” during
SEARCH (see Figure 4). If the knob is rotated
anti-clockwise the MT 100 will search lower
frequencies. When the first station of adequate
signal strength is detected the MT 100
will stop searching, the display will return
to “SCn” to show the signal strength and the
ON TUNE indicator will illuminate. Once the
station is tuned, its frequency may be stored
as one of the Presets if desired (see below),
or the search initiated again by rotating the
tuning knob in the required direction.
Search Display Mode (Figure 4)
Searching may be stopped before a station is
found by rotating the tuning knob in the
opposite direction to the current search, or by
pressing the MANUAL, PRESET or SEARCH
mode buttons.
10 Mono button
When the MONO button is pressed the tuner
is locked into MONO reception mode and
the STEREO indicator will not illuminate,
whether the tuned station is transmitting in
stereo or mono. A green LED in the MONO
button will illuminate to indicate this mode.
If noisy reception is experienced in stereo
mode, pressing the MONO button will
usually result in a dramatic improvement in
sound quality. Switching the tuner to MONO
mode also disables the inter-station muting,
so allowing very weak stations to be received.
When a station is stored as a preset (see
previous page) the MONO status is also
stored, and will therefore be recalled whenever
that preset is accessed.
11 Store button
The STORE button is used when storing the
preset station frequencies. The procedure is
as follows:
• Tune to the desired station using either
MANUAL or SEARCH tuning mode, and set
to MONO if required.
• Press the STORE button to enter STORE
mode, which illuminates the red LED in
the button. The tuner will automatically
change to Preset mode at the last used
preset number.
• If the station is to be stored at a different
preset number, rotate the tuning knob
clockwise or anti-clockwise until the
desired preset number is reached,
otherwise move directly to step 4.
• Press the STORE button again to store the
frequency at the preset number displayed.
The tuner will then automatically return to
the previous tuning mode ready to tune the
next station and the STORE button LED
will extinguish.
• STORE mode can be exited by pressing
either MANUAL, SEARCH or PRESET
buttons. The preset station data is stored in
a permanent memory and is retained when
the tuner is in standby mode, or switched
off at the rear panel.
• To Delete The Selected PRESET Station
– Whilst holding the PRESET button,
press the STORE button. Then release
both buttons.
• To Delete All PRESET Stations – While
holding the MONO button, press the
STORE button. Then release both buttons.
• These two operations can only be
performed from the front panel, not the
remote control.
remote control
handset operation
The MT 100 may be remote controlled
using a Myryad System Remote handset
which is supplied with some Myryad
Integrated Amplifiers and Preamplifiers, or
can be purchased separately. The System
Remote keys which can control the MT 100
tuner are:PRESET, MANUAL, SEARCH,
MONO, TUNE UP, TUNE DOWN, STORE,
STANDBY, DIM and keypad numbers 0-9.
Preset, manual and search
Mode keys operate exactly as MT 100 front
panel buttons.
Mono
The MONO key operates exactly as the
MT 100 front panel button.
Store
The STORE key operates exactly as the
MT 100 front panel button.
Tune up and tune down
These keys operate in a similar way to the
rotary tuning knob. A single brief key press
will have the same effect as one click step
of the knob, moving either up or down in
frequency or preset number. In Manual
and Preset modes, when a key is pressed
and held down the tuner will scan in the
desired direction.
Keypad 0-9
These keys allow direct access to any preset
station. If a preset numbered 10 to 29 is
desired, (e.g. 14) press “1”, followed by “4”.
If “1” is pressed without a second digit, the
tuner will go to preset 1 after few seconds.
Pressing any other number key, from
2 to 9, will tune instantly to the relevant
preset station. Presets 1 and 2 may be tuned
instantly by pressing “0” first (i.e. 0,1 or 0,2).
Dim
The Vacuum Fluorescent Display may be
dimmed or switched off using the DIM key.
The first press of the DIM key will switch the
display off. A second press will turn the
display on again, but less brightly. A third
press of the DIM key will return the display to
its original brightness. The display will come
on briefly if controls are used while the
display is off.
Standby
Pressing the STANDBY key sends the
command to switch your Myryad Integrated
Amplifier or Preamplifier into or out of
STANDBY mode. If your MT 100 is linked to
the Integrated or Preamp via the My-Link
then the MT 100 will also be switched into or
out of STANDBY. It is also possible to switch
only the MT 100 into or out of STANDBY
using the “Tuner Standby” command. This is
achieved by pressing and holding down the
TUNER button and then simultaneously
pressing the STANDBY button. This will
switch the STANDBY status of the MT 100
without affecting any other unit.
