The MT 100 is a full-function remote- controllable FM Stereo Tuner. It has Þxed-level low-impedance audio outputs to feed a Myr yad integrated ampliÞer or preampliÞer Ð or other high quality ampliÞer. A coaxial antenna socket is provided for a 75½ FM radio (Band 2) antenna. In addition the MT 100 has a ÒMy-LinkÓ control input and output for communication with other Myr yad products. The MT 100 offers a range of expansion possibilities: ¥ The MT 100 can be remote-controlled using the Myr yad System Remote handset. ¥ The ÒMy-LinkÓ input can be connected to a Myr yad integrated ampliÞer or pre-ampliÞer so that the MT 100 will automatically be switched on or off when the ampliÞer is switched on or off. ¥ The ÒMy-LinkÓ input/output can be coupled to other Myr yad products, which can then be remote-controlled via the MT 100's infra-red receiver Ð or vice-versa. installation and safety notes This Tuner generates ver y little heat but still requires some 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 any obstruction to the ventilation slots in the rear panel. The Tuner should not be placed in a built-in installation 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 UNIT AGAIN. IF THE LIQUID IS ANYTHING BUT WATER AND/OR ALCOHOL, THE UNIT SHOULD BE EXAMINED BY A QUALIFIED SERVICE TECHNICIAN BEFORE IT IS USED AGAIN.Do not remove the cover, or attempt to modify or repair the Tuner yourself. Refer all servicing to a qualiÞed technician. NOTE REGARDING MICROPROCESSOR CONTROLLED EQUIPMENT: ALL MYRYAD M-SERIES PRODUCTS ARE CONTROLLED BY A MICROPROCESSOR LOCATED BETWEEN THE FASCIA AND SUB- FASCIA. THESE PROCESSORS RUN WHENEVER THE UNIT IS TURNED ON AT THE REAR PANEL. LIKE ALL MICROPROCESSORS, THOSE USED IN MYRYAD EQUIPMENT ARE SENSITIVE TO CHANGES IN SUPPLY VOLTAGE. IN PARTICULAR, WHEN THE UNIT IS TURNED OFF AT THE REAR PANEL SWITCH, THE PROCESSOR MUST BE GIVEN TIME TO RESET BEFORE THE UNIT IS TURNED BACK ON. GENERALLY 60SECONDS IS SUFFICIENT. FAILURE TO ALLOW TIME FOR THE PROCESSOR TO RESET MAY RESULT IN INCORRECT PROCESSOR OPERATION. SYMPTOMS OF THIS MIGHT INCLUDE: ¥ BUTTONS THAT FAIL TO WORK. ¥ UNEXPECTED ACTIONS ETC. THIS IS COMMON TO ALL MICROPROCESSOR CONTROLLED EQUIPMENT BUT CAN BE AVOIDED BY TAKING THE FOLLOWING STEPS: ¥ MYRYAD UNITS ARE DESIGNED TO BE LEFT IN STANDBY FOR LONG PERIODS Ð YOU DONÕT NEED TO TURN THEM OFF AT THE BACK PANEL UNLESS YOU EXPECT THEM TO BE UNUSED FOR EXTENDED PERIODS OF TIME. ¥ IF YOU TURN YOUR UNIT OFF AT THE REAR PANEL, ALLOW 60 SECONDS TO ELAPSE BEFORE TURNING IT BACK ON. ¥ IF PROBLEMS DO OCCUR, TURN OFF YOUR UNIT AND LEAVE IT TO STAND FOR AT LEAST 60SECONDS. IF THE PROBLEMS RECUR WHEN YOU TURN THE UNIT BACK ON, CONTACT YOUR DEALER. accessories Your MT 100 is supplied complete with the following accessories: ¥ Separate mains power cord to suit countr y of sale. ¥ Wire antenna (300½) suitable for high signal strength areas. ¥ Balun (matching adaptor) to allow connection of the 300½ antenna. ¥ Balun interface connector where necessar y (not all countries). ¥ System Remote. poweron off my-link out in rl line output input antenna coax 75½ setting up your system rear panel connections 1Power 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 Tuner. Plug the male (plug) end of the cord into a ÒliveÓ wall socket or a suitable heavy duty extension cable. UK version: The mains plug is supplied Þtted with a 5A fuse. It should only be replaced with a fuse of the same rating (5A) which complies with BS1362. Plug wiring instructions: The wires in this mains lead are coloured in accordance with the following code: ¥ blue Ð neutral ¥ brown Ð live As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: ¥ The wire that is coloured blue must be connected to the terminal that is marked with the letter N or coloured black. ¥ The wire that is coloured brown must be connected to the terminal that is marked with the letter L or coloured red. No connection should be made to the earth terminal of a three-pin plug (marked with the letter E or coloured green or green and yellow). 2Power switch Press one side of this rocker switch (the side nearer the edge of the rear panel) to switch the Tuner ON and the other side (towards the antenna socket) to switch it OFF. When the POWER switch is in the OFF position all power is disconnected from the Tuner. In this condition the Tuner 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 in to a live wall socket) the Tuner will power up in standby mode (see FRONT PANEL CONTROLS, STANDBY,). It is recommended that the POWER switch is turned OFF if the Tuner is not going to be used for an extended period of time. 3My-link input/output When the MT 100 is used in a system with other Myr yad products all may be joined together via the My-Link and this offers three beneÞts. First, when coupled to a Myr yad Integrated AmpliÞer (e.g. the MI 120) or Pre-ampliÞer, the MT 100 will automatically be switched into or out of STANDBY when the ampliÞer is switched on, either from the front panel, or its own remote control. Secondly, the My-Link allows both the MT 100 and the Myr yad AmpliÞer to be remote-controlled via the infra-red receiver in either unit. Thus only one unit needs to be in Òline-of-sightÓ of the remote handset. Finally, the system enables the remote control of some Myr yad products that do not have their own infra-red receiver. When connected to a Myr yad Integrated AmpliÞer or Pre-ampliÞer via the My-Link, the tuner display will show the messageÒSYSTEM ONÓ during the Þve-second warm-up period. 4 Antenna input The MT 100 is Þtted with a 75½ ÒcoaxialÓ antenna socket, which must be used with a 75½ antenna (aerial). The MT 100 is supplied with a simple wire 300½ antenna together with an impedance matching adaptor (see Figure 1). This antenna is provided to ensure that the tuner can be set up and used straight Òout of the boxÓ. It is not adequate to provide full performance from the Tuner except in areas of particularly high signal strength (e.g. close to the FM transmitter). In most instances a good quality roof or loft mounted FM antenna should be used Ð see ÒAntennasÓ section on page 7. The MT 100 has different coaxial antenna sockets to suit different countries. ÒNorth AmericanÓ models are Þtted with ÒFÓ type coaxial connectors while models for most other countries are Þtted with ÒDINÓ style connectors. When using the 300½ wire antenna the matching adaptor (or balun) must be used and ÒDINÓ versions also need to be Þtted with the female-to-female adaptor supplied. See Figure 1 for clariÞcation. When you unfold the wire antenna you will note that it is in the form of a ÒTÓ. The ÒcrossbarÓ portion of the T should be stretched out horizontally and tacked in place, either on a wall or the back of a cabinet, or on the ceiling. The ÒverticalÓ section of the T goes to the tunerÕs antenna input via the balun (see Figure 1). Experiment with the position and orientation of the antenna to obtain the best reception.

5Line outputs These outputs are suited to the ÒTUNERÓ or other ÒLineÓ inputs (e.g. CD or AUX) of any integrated ampliÞer or pre-ampliÞer. Never connect to the ampliÞerÕs PHONO inputs. front panel controls 1 Standby When the Tuner is plugged into a live wall socket and the POWER switch is turned ON, it will power up in ÒStandbyÓ mode and the LED (Light Emitting Diode) in the STANDBY button will glow red. In this mode the internal circuitr y of the MT 100 is powered up but disabled, so that it consumes ver y little power and its audio output is muted by a relay. When the STANDBY button is pressed the MT 100 circuitr y will be activated, and, after a few seconds delay, the audio outputs will be enabled. During this delay period the LED in the STANDBY button will flash blue. When the outputs are de-muted it will glow green continuously. When the STANDBY button is pressed again the Tuner will be returned to standby mode. The LED in the STANDBY button will glow red again and the display will be extinguished. CAUTION: WHEN IN STANDBY MODE THE INTERNAL CIRCUITRY OF THE MT 100IS STILL LIVE, SO ALL SAFETY PRECAUTIONS MUST BE FOLLOWED. 2Infra-red receiver The infra-red (IR) remote control receiver is mounted behind the window, just above the display. It must not be obscured when the Tuner is to be operated using a Myr yad System Remote handset. Where possible it is best to arrange that the IR receiver is in Òline-of-sightÓ of the remote handset. 3Display The operation of the tuner is indicated on a high quality blue Vacuum Fluorescent Display. The tuned frequency is always displayed to the left, together with the Preset Number, Signal Strength or SCH to indicate the selected tuning mode (see below, sections 7, 8 and 9). 4 Stereo indicator This indicator is illuminated when a stereo broadcast is being received and the tuner is not switched to MONO mode. 5On tune indicator This indicator is illuminated when any FM signal, above a ver y low threshold, is received and is ON TUNE. 6Tuning knob The tuning knob is used to set the frequency in MANUAL, PRESET and SEARCH modes. The knob operates with 24 discrete clicks per revolution. The operation of the knob is determined by the mode selected (see below) but in all modes, a clockwise click will perform an incremental operation and an anticlockwise click a decrement. 7Preset tuning mode Press the PRESET button to enter ÒPreset TuningÓ mode. The MT 100 will tune to the frequency of the last used preset station and the display will show the tuned frequency and the preset number (see Figure 2). When the tuning knob is turned one step clockwise the MT 100 will tune to the preset stored with the next higher number while an anti- clockwise step will move to the next lower stored preset. The tuner will skip preset positions that have not been programmed, i.e. if station 3 is not programmed, the tuner will skip from station 2 to station 4. If the tuner is stepped beyond the highest number preset stored, it will Òwrap-aroundÓ and step back to the lowest numbered preset. Preset Display Mode (Figure 2) NOTE: PRESET MODE CANNOT BE ENTERED UNTIL AT LEAST ONE STATION HAS BEEN PROGRAMMED (SEE SECTION 11Ð STORE BUTTON) 8 Manual tuning mode Press the MANUAL button to enter Manual Tuning mode. The display shows the tuned frequency, together with a Signal strength indication (see Figure 3). When the tuning knob is rotated clockwise the tuned frequency will increase by 50kHz at each click step or decrease by 50kHz per click for an anti- clockwise rotation. Correct tuning can be obtained either by setting the correct frequency, if it is known, or by tuning until the ON TUNE indicator illuminates Ð which indicates accurate tuning. Once the station is tuned its frequency may be stored as one of the Presets if desired (see above). The signal strength indicator will display a number from 1 to 9, preceded by the letters ÒSIÓ. A signal strength of ÒÐÓ indicates no signal, whilst a signal strength of 9 indicates a ver y strong signal. Normally an indication of 4 or 5 is necessar y for a useable signal in stereo, while a Þgure of 7 should ensure that lowest noise reception is obtained in stereo. tuning mode.
