Mitsubishi DT-30 cassette deck

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.
