Technics RS-M250
A new cassette deck from Technics, the RS-M250 , is packed with a tremendous variety of convenience and handling features. And, as with all technics cassette decks, its performance represents excellent value – the RS-M250 is capable of making recordings which are virtually indistinguishable from the original program source. In fact, on a price/performance basis, Technics products traditionally have compared quite favourably with those of our competitors. The new Technics cassette deck line is no exception – it offers outstanding value at all price levels.
Versatile Microprocessor
Simply turning on the power will show you that the RS-M250 is different from other cassette decks . notice, for example, the digital tape counter. The readout is large and bright, and can be seen from across the room. One count of the counter corresponds to 2 rotations of the reels. Yet it is more accurate than many similar devices because it includes 4 fractional divisions which break down the readout more precisely – half-turns of the take-up hub can be accurately measured. But the readout is only part of the story.
Suppose you want to repeat a track on the tape, or refer back to any point on the recording. It’s easy with the RS-M250 and its microprocessor. The memory has four settings; “stop”, “off”, “play”, and “repeat”/ in the “repeat” mode , you simply press the reset button at the point on the tape you want to recall. Then, a touch of the rewind button will return the transport to this spot, where it will automatically switch into play. If allowed to continue and play the remainder of the side, the microprocessor will then instruct the transport to return to “000” where, once again, playback begins. “Play” works the same way, except that it doesn’t repeat, and “stop” simply returns the tape to the “000” point without beginning playback. For checking recordings, or finding an exact point on the tape for future reference, the RS-M250 is a very convenient deck at a reasonable price.
Effortless, Error-Free Mode Changing
The transport controls are logic-controlled switches. There’s no need to use the stop button when changing modes – just go directly into any mode (except record), including rewind, fast forward, and play. And when recording, a touch of the record button also engages both the play and the pause mechanisms automatically – then just touch the play button to begin recording. Thus, you avoid the difficulties and inconvenience of having to engage all these controls separately and manually.
If you want even more convenient operation, use the optional RP-9645 remote control module. You can control all transport functions, plus record muting, from the comfort of your listening position. There is even a convenient front panel input jack for connecting the remote control unit; when not in use, a special cover protects the jack from dust and impurities.
Simple-to-Use Features
We believe that convenience features are worthwhile only if they are easy to use – all the RS-M250’s features can be engaged and used with a minimum of effort. For example, we provide a switch which allows the use of an external timer, and the hook-up is extremely simple – the entire operation can be controlled from the front panel. The same point of view explains the door on the cassette well. It is removable for easy access to the heads for examination or cleaning. No bolts or screws – the door simply slides into place. As you can see, the RS-M250 is designed for simple operation of all functions.
Performance
Of course all the features in the world aren’t worth much if the deck lacks good basic performance characteristics. Fortunately, the RS-M250’s performance is superb, particularly in light of its modest price tag. A glance at the spec table will demonstrate our devotion to quality. And the tapes which you make with the RS-M250 will sound consistently clean, crisp, realistic, and natural. We have also included the necessary extras to ensure this excellent performance undervirtually any circumstances.
Meters
For example, our FL peak reading meters employ a peak hold readout – this means that peaks are retained on the meter for 2 seconds. Then the meters automatically reset until the next peak comes along. The 2 color readout clearly indicates the 0 dB point, so you can be sure that the recording level will always be accurate. Result? Tape recordings with low noise, low distortion, and superb fidelity.
Tape Selector Switch
Naturally, we have included a selector switch to set bias and equalization for metal tape , the latest technological advance in the cassette medium. This formulation also necessitated an improvement in the saturation flux density of the recording head itself – our improved SX record/playback head yields exemplary performance with any type of tape. The Sendust formulation also assures a long life for the head with only normal routine maintenance.
FM Recording
Recording a program from an FM signal source will also yield a very high quality recording. The front panel MPX filter switch removes the carrier pilot signal from the tape input, thereby avoiding the distortion associated with this signal.
The Technics RS-M250 – an excellent combination of fine basic performance and the features to make the deck flexible enough for a wide variety of applications. Plus, it includes something which has become a Technics tradition – outstanding value for the money.
Other Features:
2 motor drive system – one for driving the capstan and another powers the reels and the head block during transport mode switching. This system contributes to low wow and flutter and good reliability.
Input selector switch – allows you to choose between “line” and “mic” inputs. If “mic” is selected, you can utilize the 2 front panel microphone jacks.
Dual concentric input level controls – friction coupled knobs, for adjusting one channel at a time, or both together.
Output level control – useful for matching the volume output of the deck to that of your tuner and turntable, so there’s no need for repeated adjustments in volume
