-3- Dear Valued Customer Thank you for choosing the Magnum Dynalab “MD 208” Discrete Audio Receiver. Great care has been given to the design, manufacturing and selection of components for the “MD 208” Discrete Audio Receiver. This complete process insures optimum listening enjoyment for many years. The FM Section is a special design completely researched and manufacturer in house. In fact, we are the only company in the world that does their own R.F.
-4- UNPACKING YOUR MD 208 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 208 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 THE MD 208 1. Position the receiver away from any spot which may have extremes in temperatures. 2. Place the receiver on a very rigid surface capable of holding 50 pounds (22 KG). 3. The heat sinks on the side of the unit are used to keep the unit at a safe operating temperature. It is important that they are not covered or the unit is not installed in a closed area where there is little air circulation.
-6- SET UP OF THE INTEGRATED AMPLIFIER SECTION OF THE MD 208 (All numbers correspond to the product diagram on Page 11) 1. Now that you have positioned the MD 208 correctly and plugged it into the appropriate AC power supply, you are ready to hook it up to the speakers. Hook up your speakers to the receiver insuring that the positive (+) terminal on the speaker is hooked up to the positive (+) output terminal on the receiver, likewise that the negative (-) is correctly hooked up.
-7needle on the tuner continually reads more than zero, move the antenna to a different location or rotate the antenna. If this does not correct the problem, a better or different antenna may be required, please see Reception Techniques at the back of the manual. 8. You are now ready to listen and search for your favorite stations across the frequency. If you encounter difficult reception situations please read the Reception Techniques section at the back of the manual.

- 11 - CONTROL FUNCTIONS (Numbers correspond with product diagram on page 11) 1. VOLUME CONTROL – The digitally controlled precision volume control allows you to vary the volume from 0-50. Note that it is not a linear volume control – therefore volume changes will vary more as you turn the control at higher levels than at lower levels. 2. POWER – Switches the power (AC) on and off to the receiver. 3. INPUT SELECTOR – Changes the input source. 4.
- 12 - 12. FREQUENCY DISPLAY – Shows the tuned frequency from 87.5 MHz thru to 108.5 MHz. This readout is controlled by the tuning control. 13. CENTER TUNE METER – Indicates the setting of the tuners front end, in normal situations the tuner should be tuned so that the needle is in the center.

- 14 - 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.
- 15 - 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.
