Lexicon Power Amplifier ZX-7

Những đặc điểm nổi bật của Lexicon Power Amplifier ZX-7:

It’s a fully balanced (differential) design, with each amplifier channel being a module inside the chassis. The modular approach seems to be the one that manufacturers have settled on, as it makes assembly and maintenance much easier. If one channel goes bad, you slide the defective module out and slide a new one in. No messing around with circuit boards that have electronics for more than one channel on them. The only parts that are shared by all the modules are two toroidal transformers.

The front of the ZX­7 is very conservative (as is Mark Levinson). The quality of chassis machining is there, but without any frills. The front plate is thick and routed with the Lexicon logo.The only control is the On/Off push­button that moves the amplifier from Standby to On.The rear panel has XLR and RCA input jacks for each channel, one pair of binding posts for the outputs, and two AC power cord jacks with on/off toggles. These switch power on to the two toroidal transformers. Two are required because the ZX­7 can output 3,000 watts into 4 ohms, which means one 20 amp circuit won’t handle it.
