If you are an audio
enginneer, you'll get the most out of the new Mitsubishi Dt-30 in a day or two.
You get dynamics, fidelity, color and subtlety like you never dreamed of. If,
however, you are merely a gifted amateur, it will take longer. Because the DT-30
is somewhat like a race horse. It runs best under a great jockey. It is more
sophisticated, more complex, and more challenging than systems costing twice as
much. It has, for example, recording head azimuth adjustment, so you can fine
tune for optimum performance with any cassette. It has internal standard
oscillators, so you can make acurate and minute bias adjustments.
It has a 3-head
structure, so that you can monitor what you're recording while you're
recording. Although a professional would be accustomed to this level of
instrumentation, you may not be.
Just remember this.
The DT-30 is only a machine. With time and care and devotion, you can master
it. And produce tapes that are as good as any in the world. Consider the
features you have on your side.
A dual-capstan
transport system that's guaranteed to reduce Wow and Flutter by 30% or more. An
automatic spacing-pauser that adds a short blank space between each segment you
are recording.
A peak-hold switch
that freezes the dB indicaator at its highest level, long enough for you to
make adjustments.
We proudly introduce
our potent, eager, demanding, sensitive, beautiful DT-30 cassette deck.
