You can't say you've fully experienced the world of 2-track 38cm/s performance unless you've immersed yourself in it to this extent. The TD-5000SA approaches the 75 dB dynamic range limit as a program source (the limit for disks is 65 dB), and once you're hooked, it's so fascinating that you won't be able to escape. The TD-5000SA master recording deck incorporates the best of technology from every angle, including the first open deck to feature an SA head. It's a high-performance deck that seeks the ultimate in 2-track 38cm/s performance. The newly developed SA (Sendust alloy) head is used for both recording and playback. It is an evolution of the SF head, which was perfected using JVC's proprietary technology and has been supplied for commercial use. By evaporating a high-hardness Sendust alloy onto the tape sliding surface of the Permalloy core, it has achieved a high level of magnetic properties (sound quality and wear resistance) that have been considered extremely difficult to achieve up until now. This is the third head type that maintains the fine, rich sound quality of Permalloy for long periods of time over a wide frequency range. A unique automatic control circuit is provided to keep the back tension constant and improve the stability of tape running. The rotation speed of the supply reel is counted by a photoelectric pulse detection mechanism, and the motor drive current is controlled according to the remaining amount of tape. In addition to a purely electronic IC logic control circuit, a motion sensor circuit that can immediately switch from FF or REW to PLAY is built in. Utilizing the pulse detection section of the automatic back tension control, the circuit operates as soon as the supply reel stops, and this system commands the switch to PLAY without any time lag. The supply side is a one-way damp tension arm, and the take-up side is a double action tension arm. Both have locks, making it easy to load tapes and edit. Other features include highly stable upper and lower double support capstans, a normal/variable switching bias adjust system with built-in reference oscillator, a MIC/LINE summing type OP amp mixer circuit with no level interference, a -30dB~+10dB wide scale high precision VU meter with mirror, and a new No. 10 reel adapter that does not require height correction, making this a heavy equipment worthy of a high performance machine.
