Aiwa AD-M800U deck

Stereo Cassette Deck

Only the very best decks have three heads. But Aiwa's metal compatible deck adds wireless remote control. And a brain DATA. Aiwa's exclusive microcomputer Digital Automatic Tape Adaptation.

 

The Data System

In less time than it takes to read what DATA does (…DATA does it). Set DATA's computer and press Start. LED's begin to flicker. One each for LH, FeCr, CrO₂, and Metal. DATA's electronic senses analyze the tape and an LED light up as the other go out. Now you (and DATA), know the kind of tape being used. Another LED flickers and lights. Bias is set for best frequency response using a built-in 6 kHz reference signal. The next LED flickers and lights Dolby levels are calibrated and set using a 400 Hz reference signal.

Two LED's remain. One flickers and lights. EQ-M is set, equalization for the mid-range 5 - 10 kHz. Then the next, EQ-H, equalization for the high, 10 - 18 kHz range is set.

Further down the panel an LED lights. It's green . You're ready to record. But, if the red LED lights instead, the machine's not wrong. The tape is. Get another tape or switch to amnual over-ride.

Once DATA is set, you record with maximum sonic quality, regardless of whose tapes or what type you're using. And Data stores the tape analyses - at your comand - in its memory bank. Four different tapes of your choice. Cassette recording was never so precise. So precise, and so fast.

 

It All Adds Up

Precise sophistication like Data deserves features and performance to match. You've got them, starting with built-in wireless remote control for full-function performance from across the room, using dependable, invisible infrared projection. You have 3-head performance using linear, ultra-hard sendust heads with Aiwa's exclusive V-cut geometry for contour effect elimination doing away with roughness at low frequencies. And each head is designed for best performance at its specific function.

Add Double-Dolby, IC logic controls, dual motor drive, backlif VU meters with 5-step peak reading LEDs, auto-repeat, memory replay, oil-damped eject and more.

The sum of the parts is frequency response of 30 - 17,000 Hz using Metal tape. Signal-to-Noise Ratio ratio of 68 dB with FeCr, Dolby on. Woa and Flutter is 0,04% WRMS.

This is one of the finest decks you can get at any price. If you prefer, it's avaliable in black with rack handles as the AD-M800BU.
