Intended for systems where the additional output of the RX-7 or the ZX-7 is not necessary, the Lexicon GX-7 – with 125 watts per channel into 8 ohms – has more than enough power to drive most multi-channel speaker systems. When driving a 4 ohm load, the output of the GX-7 increases to an impressive 188 watts per channel. In order to facilitate easy system integration, the GX-7 includes a 12-volt trigger input on the rear panel so that it can be powered up remotely by a separate device with an output trigger, such as a Lexicon Digital Controller. A rack mount is also available. With its clean, quiet power, the GX-7 serves as an exceptional addition to any multi-channel home entertainment system.
Reference AV say:
“ The Lexicon GX-7 offers superb performance for systems with high efficiency speakers, or as an additional amp to power surround channels, in a case size that doesn’t take up too much space in the rack! ”
