-3- A Message From the President Thank you for choosing the Magnum Dynalab MD 100T FM Tuner. Great care has been dedicated to the design, manufacturing and selection of components for the MD 100T FM Tuner. This complete process insures optimum listening enjoyment for many years. The RF ‘front- end’ of all Magnum Dynalab tuners is an exclusive in-house designed and manufactured component.
-4- UNPACKING YOUR MD 100T Carefully inspect all sides of the shipping carton for damage. If there are marks or holes in the carton make note of the location in relation to the unit inside. Any obvious dents or scuff marks should alert you to the possibility of damage. Carefully remove the MD 100T from the end caps and wrapping, inspect all sides. Pay special attention to the corresponding areas on the unit where damage was found to the shipping carton.
-5- SETTING UP YOUR MD 100T 1. Place your tuner the shortest distance possible from your pre-amplifier/ integrated amplifier, being careful to avoid areas that may cause extreme temperatures. 2. Connect your tuner to the pre-amplifier, using cables/ inter-connects that are consistent with the rest of the inter-connects in your system. For a single ended (un-balanced) system the cables will be connected to the RCA connectors labeled “unbalanced out” on the rear panel of your tuner to an unused aux.
-6- CONTROLS AND FUNCTIONALITY (Letters correspond to the diagrams on the following page) A. POWER – Turns the power (AC) on and off to your tuner, with the optional remote system this switch must be left in the “OFF” position. B. MUTE – In the “ON” position, a limit is now placed on your tuner. While scaling up and down the FM dial, weak stations will be overlooked so that no alarming noises will be heard while looking for programs.
-7- DISPLAYS AND METERS G. SIGNAL STENGTH/ MULTI-PATH METER – This meter’s readout is dual function and is controlled by switch E (shown on diagram). H. FREQUENCY DISPLAY – Displays the station via a numeric value, the frequency that your tuner is dialed into. Display ranges from 87.5 MHz through 108.5 MHz. This readout is controlled by the tuning knob (F on diagram). I. CENTER TUNER METER – Indicates the setting of tuners front end in relation to the station you are tuning to.
-8- CHECKING OUT YOUR MD 100T 1. Place your power switch to the “ON” position (A on diagram). This should turn on your tuner’s meter lights and frequency display. 2. Place your STEREO/MONO switch (C on diagram) to the Stereo setting. 3. Place your bandwidth switch (D on diagram) to BW1. 4. Place your Mute switch (B on diagram) to “ON” position. 5. On your preamplifier/ integrated amplifier select the input that your MD 100T tuner is connected to. 6.
-9- TUNER REMOTE (OPTIONAL) If your tuner was ordered with the RC1 “PRECISION REMOTE SYSTEM”, here are the operating instructions. 1. The power switch should be off on the front panel of the tuner 2. Using the remote handheld, push the “POWER ON” button. You will see the tuner turn on. 3. To tune with the handheld, push and then hold either the “TUNE UP” or “TUNE DOWN” button until you reach the desired station. The longer you hold the button the faster the frequency changes.

- 11 - TROUBLESHOOTING PROBLEM No sound, meter lights are not on No sound, meter lights are on Low signal strength POSSIBLE CAUSE • Power cord disconnected • Power off at source • Interconnect not properly installed • Preamp set to incorrect source • Preamp set to tape monitor source, if preamp has such a function • Power amplifier is off • Antenna not connected properly • Incorrect antenna • Station too distant • Improper antenna position/ placement Intermittent sound • Mute switch is in the “ON” pos
- 12 - RECEPTION TECHNIQUES Antenna Cabling: The lead-in cable from the antenna is often the weakest link in the FM system. Some time spent on selection and matching will yield dramatic results when it comes to noise reduction in weak signals. A good grade of 75 ohm coaxial cable will provide very sufficient signal passage, along with effective shielding against interference. Without effective shielding your coaxial cable can in fact become an antenna in itself.
- 13 - Magnum Dynalab offers the MD ST-2, an excellent vertical ½ wave antenna Folded Di-Pole - This is the most common and simplest of all antennas, most people are familiar with the 79 cent piece of wire you received with most electronics gear (generally provided with a tuner or receiver). This piece of wire is bi-directional and the performance of it is affected by the angle that the signal hits the piece of wire.
