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.SPECIFICATIONSOutput Power - 125W RMS per channel into 8 from 20Hz to 20kHz- 188W RMS per channel into 4 from 20Hz to 20kHzMinimum Speaker Impediance - 4Frequency Response - 20Hz to 20kHz +0.1dB/-0.5dB- 10Hz to 40kHz +0.1dB/-1.5dBTHD - Less than 0.05% at full power ratingsSignal-to-Noise Ratio - Greater than 100dB, ref 125W/8 Ohms (30kHz bandwidth)IM Distortion - Less than 0.05% at full power ratingsCrosstalk - Greater than -80dB @ 1kHz (30kHz bandwidth)Damping Factor - Greater than 200 @ 20Hz (ref 8 Ohms)Input Sensitivity - 1V for 100W out @ 8Input Impedance - Minimum 10KGain - Minimum 28dB
