Equipped with an over-sized toroidal transformer and individual power supplies for each of its seven channels, the GX-7 combines considerable output with quiet, low-distortion operation. Because each channel has its own power supply, the GX-7 has significantly improved channel separation. Intended for systems where the additional output of the RX-7 or the ZX-7 is not necessary, the 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 buy 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.
