Lexicon ZX-7 Multi-Channel Audiophile Power Amplifier. 120 Volt. Uses two power cords. *Packed in the box, the amp weighs 152 lbs. And it weighs approximately 202 lbs. loaded on a pallet. *New was $10,000. Still in the factory original box and it is virtually like new. 10 out of 10. *You will never find another Lexicon Amplifier in this new of condition. *A formidable combination of power and finesse, the ZX-7 is the obvious choice for audio enthusiasts looking for maximum performance from their listening systems. *Take one look at how massive it is and you will see why it continues to be a world class, multi-award winning amplifier. *Along with its exceptional sonic performance, the ZX-7 is equipped with sophisticated protection capabilities. *Advanced optically coupled protection circuitry safeguards the ZX-7 from damage caused by excessive heat, short-circuits, device failures, miswiring, internal faults, reactive loads, and IT EVEN PROTECTS YOUR EXPENSIVE LOUDSPEAKERS from DC Current and frequencies below 10Hz. Because the protection circuitry is optically coupled for each channel, it is completely isolated from the audio signal path, eliminating any potential degradation of the audio signal inherent in traditional protection schemes. *The ZX-7 features a true balanced topology. Each of its seven channels consists of two amplifier stages, one for each side -- both positive and negative -- of the wave form. *The positive input signal is amplified by the positive amplifier and the negative input signal is amplified by the negative amplifier when a balanced signal is applied to the input. This lowers noise, lowers distortion, and eliminates interference from external stray electronic fields and anomalies in the input signal from outside interference. Music reproduction benefits from a cleaner soundstage and increased dynamics, while the presentation of subtle detail is improved appreciably due to the significantly lower noise floor. *Along with its exceptional sonic performance, the ZX-7 is equipped with sophisticated protection capabilities. *Advanced optically coupled protection circuitry safeguards the ZX-7 from damage caused by excessive heat, short-circuits, device failures, miswiring, internal faults and reactive loads, plus it protects loudspeakers from DC and frequencies below 10Hz. *Because the protection circuitry is optically coupled for each channel, it is completely isolated from the audio signal path thus eliminating any potential degradation of the audio signal inherent in traditional protection schemes. *The ZX-7 is a fully balanced power amplifier from input to output with completely symmetrical circuit design. In other words, each channel consists of two complete amplifier circuits: one driving the positive input signal and the other driving the negative input signal. *With 7 channels, this translates into 14 separate amplifier circuits per chassis. Internally, the ZX-7 utilizes dual massive toroidal transformers and ample filter capacitance. The ZX-7 also employs heavy-duty, chassis-mounted input and output connectors including balanced audio inputs via RCA or XLR connectors. *A trigger input connector (to power on and off with the preamp/processor) allows the amplifiers to be controlled with associated components such as preamp/processors. *Equipped with advanced thermal, current, DC and speaker protection, the ZX-7 power amplifier can be matched with most loudspeakers. *The ZX-7 also features embedded protection against short circuits, component failures, mis-wiring and internal faults. Uses two 110 Volt electrical plugs. See and hear your home theater in a whole new light. I will tell you that this amplifier really puts out the juice. *With all media, including music and movies, your room just shakes with music and sound effects. Deep bass explosions are no problem for the high current capability of the ZX-7. *7-channel Amplifier *Specs: FREQUENCY RESPONSE 20Hz to 20kHz +0.1dB/-0.5dB; 10Hz to 40kHz +0.1dB/-1.5dBINPUTS INPUTS 7 RCA | 7 XLR INPUT IMPEDANCE Minimum 10KOhms INPUT SENSITIVITY 1V for 176W out @ 8 Ohms RATED OUTPUT POWER INTO 4 OHMS 450W RMS per channel into 4 Ohms from 20Hz to 20kHz RATED OUTPUT POWER INTO 8 OHMS 300W RMS per channel into 8 Ohms from 20Hz to 20kHz *Minimum Recommended Speaker Impedance 4 Ohms SIGNAL-TO-NOISE RATIO Greater than 100dB, ref 300W/8 Ohms (30kHz bandwidth) *TOTAL HARMONIC DISTORTION (THD) Less than 0.05% at full power ratings IM DISTORTION (THD) Less than 0.03% at full power ratings CROSSTALK Greater than -60dB @ 1kHz (30kHz bandwidth) GAIN Minimum 31dB TRIGGER INPUT 3.3 to 24 Volts DC Minimum ± 10%, 3.5mm T/S jack *POWER REQUIREMENTS 110V 60Hz 12 Amp (domestic) SPEAKER CONNECTIONS 7 pairs of heavy-duty, gold-plated binding posts *DAMPING FACTOR Greater than 400 from 10Hz to 400Hz *WEIGHT 139 pounds (63.05 kg) DEPTH 20.3-inches (including handles) 19.3-inches (not including handles) WIDTH 17.2" HEIGHT 9.5" •300 watts x 7 channels •Full Balanced Topology •Completely symmetrical circuit design •Dual oversized toroidal transformers •4 hand-graded output devices per channel •Advanced optically coupled protection for each channel •High-power supply voltage for extra headroom at the outputs •Stable with mismatched, reactive, or unusual loads •Thermal protection against overheating •Rack-mount option available •Staggered power-on sequence to reduce noises from connected equipment and to limit turn-on AC draw •High damping factor (no output relays) ensure realistic, impressive bass transients •Includes the power amp, all original packaging, manual and 12v trigger The Lexicon ZX-7 is an amazing amplifier.
