-3- A Message From the President Thank you for choosing the Magnum Dynalab “MD 105” FM Tuner. Great care has been given in the design, manufacturing and selection of components for the “MD 105” FM Tuner. This complete process will insure that your listening experience will be optimized for years. The front end of all Magnum Dynalab tuners is an exclusive “in house” designed and manufactured component, we are the only company in the world that does their own R.F. “Front-end”.
-4- UNPACKING YOUR 105 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 105 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 105 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 “output to preamp” on the rear panel of your tuner to an unused aux.
-6- CONTROLS AND FUNCTIONALITY A. INPUT SELECTOR – Switches the MD 105 between digital inputs found on the rear panel of your tuner. Only functioning when optional DAC has been purchased. B. 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. C. MUTE – In A the “ON” position, a limit is now placed on your tuner.
-7- DISPLAYS AND METERS G. MULTI-PATH METER - This meter indicates the amount of multi-path, the lower the reading the better. H. SIGNAL STENGTH– This meter readout indicates the amount of signal the tuner is receiving, the higher the better. I. 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.
-8- CHECKING OUT YOUR MD 105 1. Place your power switch to the “ON” position. This should turn on your tuner’s meter lights and frequency display. 2. Place your STEREO/MONO switch to the Stereo setting. 3. Place your bandwidth switch to BW1. 4. Place your Mute switch to “ON” position. 5. On your preamplifier/ integrated amplifier select the input that your MD 105 tuner is connected to. 6. Rotate the tuning knob on your tuner until sound is heard through your speakers.
-9- TUNER REMOTE (OPTIONAL) If your tuner was ordered with the RC4 “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 red “TUNER” 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.

- 13 - 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.
- 14 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. There are quite a number of di-pole antenna designs; they work well in areas of strong signal strength, such as local stations.
