The AIWA AD-6800 is a two motor, 3 Head deck ... that actually has one motor and two heads. For the all essential tape transport there is a 38 Pulse FG Servo Motor combined with a big flywheel while the second motor is only for the automatic cassette loading system. The 3 Head designation seen on the front panel of the deck is not for what we usually know, a deck with monitoring capabilities, there's no Monitor function on this deck. Actually the deck is a two head deck (Ultra-hard long-life FGH - ferrite head) but it has a 3rd head, called Test head which is only active during the recording of the test tones that helps you to adjust the BIAS for all tape types. This system is called by AIWA - FRTS (Flat Response Tuning System). Test signals from two built-in oscillators of 400 Hz and 8 kHz are simultaneously recorded and monitored in order to adjust the bias after setting the Test Head Azimuth. This procedure optimizes the performance characteristics of all types and all brands of cassette tape assuring high output, low noise, wide dynamic range and exceptional clarity. Another unusual but nice feature of the deck is the double level meter with one indicator for VU level and one for Peak levels (with Peak hold) Speciifcation: Wow and flutter 0.05% (WRMS) | Frequency response 20-19000 Hz (FeCr) | Dimensions 450*162*335 mm | Weight 10 kg)
