At first glance the VZ-3000Z looks like a very large 3-piece boombox, but it really isn't, because it can't accept batteries, and there's no way to carry all of it together as one piece. The center unit measures 597mm wide, 378mm tall, and 173mm deep, and it weighs 14.6 kg. The speakers measure 220mm wide, 378mm tall, and 220mm deep, and they weigh 4.7 kg each. They contain 160mm woofers and 50mm tweeters.
The turntable in this system is capable of playing both 18cm and 30cm records, and it can play both sides of the record without needing to be flipped. This is made possible because there is one needle on each side of the record. They're mounted on parallel linear tracking mechanisms, and driven by a single motor. Thus both of them move across the record simultaneously, but only one of them is actually touching the record at any given time (a solenoid determines which one to engage or retract).
Electronics Australia reviewed one in its January 1982 issue, and found that the turntable's peak wow and flutter was only 0.1% DIN weighted, which rivaled or even beat many home turtables at the time.
The vertical VU meter appears to have 10 LEDs, but it's really only 5, with two "windows" for each LED.
