A Message From the President

Thank you for choosing the Magnum Dynalab “
of our finest FM tuners. Great care has been given in the design, manufacturing
and selection of components for the “

MD 108 T”

years of listening enjoyment.

The MD 108 T 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. The MD 108 T uses our proprietary TRACC (Triode
Reference Audio Control Center) technology creating the most transparent
listening experience possible. Special torroidal transformers for the RF section, as
well as a separate large torroidal transformer for the audio stage, were chosen
because of their high performance characteristics.

We appreciate your decision to purchase the MD 108 T FM tuner. Please feel
free to contact us if you have any comments or suggestions on improving your FM
listening experience. Call us on our toll free number, 1-800-551-4130 or contact
us via email at: [e-mail]. We at Magnum Dynalab are here to
serve your source audio source needs.

Respectfully yours,
Larry Zurowski

UNPACKING YOUR MD 108 T

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. Open
the top flaps and carefully lift the transport case out of the carton. Carefully
remove the MD 108 T 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. If damage is evident, document the type and extent of the
damage, then repack the unit and call the dealer.

If your unit was delivered by a common carrier (Eg. UPS) and you have found it to
be damaged, contact the carrier immediately for instructions.

KINDLY DO NOT SEND THE UNIT BACK TO THE SHIPPER UNTIL YOU HAVE BEEN
ASKED TO DO SO. SHIPPNG THE UNIT BACK PREMATURELY MAY VOID ANY
CLAIM FOR DAMAGE THAT YOU MAY HAVE.

DO NOT DISCARD THE PACKING MATERIALS AND CARTONS. Should there be a
necessity to return the unit for any reason, it must arrive safely and suitably
packaged in order for our receiver to accept it from the carrier. Also, if the unit
has incurred damage as a result of improper packaging, it is not likely that a
claim for the damage against the carrier will be successful.

Likewise, we will ship your unit back to you only in factory-approved packaging,
However, if the unit were to arrive at the factory on anything other than factory
approved packaging, we reserve the right to return same in factory-approved
packaging and charge the cost of the packaging to the shipper. This is the only
way we can assure you of a safe return (damage by carrier excepted).

CONTROL FUNCTIONS

The front panel controls consist of the following functions (Each function is clearly
displayed on the

A. POWER: Controls the power to all display functions. All functions are kept in

stand-by mode. Any LEDs on the front that are lit will stay lit.

B. MUTE: Controls the elimination of inter-station noise. It is recommended that,

when receiving marginal signals, the mute be set to off. This will eliminate
intermittent loss of signals that fall below a specific signal value. The LED
located above the station selector knob indicates when the mute is activated.

C. STEREO: Controls whether the tuner is operating in Stereo or Mono mode.

The LED located above the station selector knob indicates when the tuner is
operating in stereo.

D. BW1: Controls the IF super narrow setting. This setting should only be used in

extreme reception conditions of adjacent channel problems.

E. BW2: This setting combines excellent frequency response with high adjacent

channel selectivity.

F. BW3: Controls the ultra wide IF setting and offers the best frequency

response.

G. BLEND: In the “ON” mode, the stereo signal strength is sampled continuously

in the Blend monitor circuit. Should the signal strength fall below the level
required for full quieting with maximum stereo separation, the blend circuit will
automatically narrow the stereo separation proportionately to minimize the
noise that might otherwise be generated in the multiplex circuit.

H. DIM: Used to extend the life of all display components especially the magic eye

by reducing their intensity.

I. TUNING KNOB: Rotating this control drives a precision ten turn potentiometer

that selects the desired frequency.

J. METERS: The left hand meter displays multi-path, see the section on

Aids.

K. CENTER TUNE MAGIC EYE: Provides a visual display for fine tuning the

frequency to maximize stereo separation and minimize noise. Tune the unit to
