A Message from the President Thank you for choosing the Magnum Dynalab MD 109 Reference FM Tuner complete with our World Source Platform. Great care has been taken in the design, manufacturing and selection of components for the MD 109 Tuner in order to ensure many years of listening enjoyment. The MD 109 is the culmination of years of research and development. We have expended considerable effort at every phase of the design process to achieve the highest level of performance.
UNPACKING YOUR MD 109 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 scuffmarks should alert you to the possibility of damage. Open the top flaps and carefully lift the transport case out of the carton. Carefully remove the MD 109 from the box and wrapping, inspect all sides.
CONTROL FUNCTIONS The MD 109 is equipped with an audio sensing circuit, which protects the unit from any unsafe operating conditions. If an unsafe operating situation should occur the unit will automatically be muted, and if the fault lasts more than two minutes a light will flash on the circuit board and the unit will not come back on until serviced The following functions are displayed clearly on the touch screen. Each funtion’s utility is explained below. 1.
. TUNING KNOB: Rotating this control drives a precision decoder that selects the desired frequency. When fine-tuning manually you must turn the knob slowly as the decoder is very precise. 7. METER: The left hand meter displays signal strength. The higher the number the better the performance. The right hand meter displays center tune, optimum operating position will be in the middle. 8. FREQUENCY DISPLAY: Displays the frequency that you are tuned to. 9.
INSTALLING THE MD 109 1. Position the tuner the shortest distance from your preamplifier. Avoid putting the unit where there are extremes in temperature. 2. Make sure that the MD 109, with specially designed feet using Vibrapod isolators, is safely positioned on a shelf designed to hold at least 60 pounds (26.55 Kg) 3. Remove the AC cord from the pouch on the lid of the carrying case and plug it into the AC receptacle at the rear of the unit. DO NOT PLUG THE CORD INTO THE WALL POWER SOURCE AT THIS POINT. 4.
9. To turn on the unit push the power button. At first the screen will display “warming up” as the components are brought up to a safe operating condition. Once the safe operating condition is attained, the screen that is associated with the setting of the input knob will appear. If you are using it in the FM tuner mode, FM will appear on the left side of the screen. Note: Each time the tuner is turned “ON”, there is a 25 second delay before the tuner will operate.
STEREO SUPER NARROW BLEND MUTE PRESET 03 MONO NARROW / WIDE FM TUNER 99.1 POWER STEREO BAND BLEND MUTE MHz PRE DIM Extra Text 11. To tune the tuner you have three options: a. Use the tuning knob on the right b. Use the tune up or down arrow with the MHz position displayed on touch screen c. Use the remote control using the tune up and down buttons 12. The tuner is now in a safe operating mode. 13. To turn the MD 109 off push the power button on the screen, the screen will become dark.
PROGRAMMING THE TOUCH SCREEN The touch screen is designed to last 10,000 hours. Once the unit has been turned on and the touch screen has been activated it will be at full brightness. After two minutes of inactivity (no touching) the screen will go into a sleep mode, this sleep mode (50 % brightness) will lengthen the life of the screen. To activate the screen touch any point on the Magnum Dynalab logo, use the remote hand held or turn the right hand knob (tuning dial).
LAYOUT REAR PANEL INPUTS: All inputs are electrically isolated from the chassis to insure that the ground plane is not compromised. The MD 109 is equipped with two module windows, these windows will be replaced if a DAC or an alternative source is added to the MD 109. When another source is added to the unit the software will sense this new device and setup the touch screen accordingly. This new input will be recognized when the left hand knob is set to the input description i.e.
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.
outdoors, but regardless of whether it is installed indoors or outdoors, the higher that you can put it the better it will perform. 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 folded di-pole you received with most electronics gear (generally provided with a tuner or receiver).
OPERATING THE CONTROL SYSTEM USING THE HANDHELD 1. To turn on the power push the on button, to turn the power off push the off button 2. To tune up and down push the tune up and tune down buttons 3. To directly access a station, push the numbers representing the frequency of the station. 4. To store presets: a) Tune the station frequency you want to store, make sure you are tuned perfectly tuned to the station (as indicated by the center tune meter).
