ZX-7/RX-7 Getting Started
1-3
HIGHLIGHTS
• ZX-7: 300 Watts per channel @ 8 Ohms
RX-7: 200 Watts per channel @ 8 Ohms
• Dual oversized toroidal power transformers with extraordinarily
low DC resistance and thermal protection
• High-power supply voltage for extra headroom at the outputs
• Stable with mismatched, reactive, or unusual loads
• Thermal protection against overheating
• Speaker protection against DC and frequencies below 10Hz
• Protection against short circuits, device failures, mis-wiring, and
internal faults
• Trigger input for power control from an external device
• RCA and XLR inputs
• Gold plated input and output connectors
• Rack-mount option available
• Noise elimination
• Delayed audio turn-on to eliminate noises from driving equipment
• Completely symmetrical circuit design which ensures optimal
audio sonality
• Hefty power supplies with lots of filter capacity ensures rock-solid
bass
• High damping factor (no output relays) ensure realistic, impressive
bass transients
• Advanced protection circuitry ensures reliability under any sort of
user abuse
INSTALLATION CONSIDERATIONS
To ensure optimal performance, pay particular attention to the
instructions below and to other precautions that appear
throughout this user guide.
DO be careful when moving the amplifier, as it is very heavy.
DO install the ZX-7/RX-7 on a solid, flat, level surface such as a table
or shelf. The ZX-7/RX-7 can also be installed in a standard 19-inch
equipment rack using an optional rack-mount kit available from an
authorized Lexicon dealer.
DO select a dry, well-ventilated location out of direct sunlight.
DO NOT install the ZX-7/RX-7 on a surface that is unstable or
unable to support all four feet.
DO NOT expose the ZX-7/RX-7 to high temperatures, humidity,
steam, smoke, dampness or excessive dust. Avoid installing the
amplifier near radiators and other heat-producing appliances.
DO NOT install the ZX-7/RX-7 near unshielded TV or FM antennas,
cable TV decoders, or other RF-emitting devices that might cause
interference.
DO NOT place the ZX-7/RX-7 on a thick rug or carpet, or cover the
ventilation holes in the chassis, as this might prevent proper cooling.
DO NOT place the ZX-7/RX-7 on a windowsill or any location
exposed to direct sunlight.
DO NOT stack the ZX-7/RX-7 directly above heat-producing
equipment such as another power amplifier.
