In keurig nette optische en technische staat Sony walkman
Model: WM-EX560
The WM-EX560 was a stereo cassette player Walkman, manufactured by the Sony Corporation in approximately 1998 with Dolby Noise Reduction (DNR) decoder, Mega Bass and Groove sound mode options, and Automatic Music Sensor (AMS). This unit operates on a single AA sized battery, and with the Sony alkaline LR6 (SG) battery, you can get up to 29 hours playback time.
This model came in black, and silver with blue tint options. The cassette compartment lid is metal whilst the centre portion is plastic.
The WM-EX560 is part of a series of advanced Walkmans ever made. It has the M6576 integrated circuit (IC) manufactured by the OKI Corporation, utilising CMOS silicon-gate technology. This IC is a 4-bit microcontroller, which operates on as little as 0.9 V. It has built-in RAM, ROM, and crystal oscillator circuit. Amazingly, it also has a serial I/O port, and an instruction set of 73. This little computer in a chip takes care of the operational logic of this Walkman.
The audio IC is the powerful TA2072AF by the Toshiba Corporation of Japan. Toshiba took over where Sanyo left, and what we see is a highly evolved IC that not only processes audio but also does it by using extremely little power. This is a dual playback preamplifier, sound processor, and headphone power amplifier in one package. They also managed to pack the entire Dolby noise reduction circuitry within this IC, hence the Dolby logo on the chip package. The sound quality is very good.
Inside the cassette compartment, there are micro switches that detect the type of cassette inserted. The internal computer then automatically sets the appropriate bias, normal (type 1), chrome (type 2), or metal (type 4).
The tape transport is also advanced. This unit uses a stepper motor, and consequently the tape speed is smooth. The MM1279 is a stepper motor driver IC, which contains the servo and motive control circuitry. This IC also manages the power to the stepper motor.
Overall, I thought this was a good walkman, and ideal for the collection.
