Magnum Dynalab MD-90 Brochure

As successor to the FT101A, one of the most sensitive, selective and sonically accurate FM tuners of our

time, the continues the tradition by re-defining state-of-the-art in analog FM tuner design.MD-90

As did the FT-101A, the combines the very latest in discrete, analog technology. Its highly

renowned MOSFET front end provides 3 stages of very careful and precise amplification. Here even the

most fragile of signals is strengthened and further defined by using highly effective "group delay"

filtering. The result is a sonically correct audio signal, one that contains all the inherent richness and

brilliance of the source being broadcast.

MD-90

In addition to the features offered by its predecessor, the now offers even greater selectivity in
order to deal with urban signal congestion. The in house manufactured 3-stage RF front end is

sure to extract the most intricate signals from amongst the milieu of FM congestion that abounds in
today's urban markets. Additional support is given through our custom , which
constantly monitors and varies your stereo separation insuring optimal "stereo quieting" during your

listeing sessions.

The now incorporates all functions in a totally redesigned motherboard. This integration has

provided the necessary design efficiencies to allow consistently higher levels of selectivity to be

maintained. Along with added selectivity, the has a redesigned power supply circuit that maintains

the tuner circuitry at standby at all times when the tuner is connected to a live AC source. The can

now also house the analog remote system (FTR) inside the chasis allowing for precise analog tuning

through the optional infra red remote control. (sold optionally)

Frequency tuning is via a precision potentiometer which provides a precise, filtered voltage for the tuning

varactors. Visual output is via the digital frequency display. The actual tuning mechanism consists of an

ultra smooth, large, front panel control knob.

Function switching is provided through tactile, toggle switches with oversize replaceable paddles.

WHY ANALOG?

In contrast with the frequency synthesis method of tuning, analog is not dependent on a digital

microprocessor chip to establish the tuner's receive frequency. With analog, tuning is accomplished using
specially-selected, discrete components in the tuner's critical "front end." In the Magnum Dynalab design,
these components are selected and matched so that a unique balance of sensitivity, selectivity and sound

can be maintained.

However, the most significant advantage in analog is that is delivers control into the hands of the user.

With the MD-90, infinite tuning is available in order to establish maximum stereo separation or to detune

slightly in order to minimize on-frequency noise. With frequency synthesis tuners, this capability is

offered usually in fixed, 50KHz steps. While FM stations themselves are rarely found to be transmitting

outside the +-2KHz standard, FM station signals that are rebroadcast over cable may not be quite so

precise.
