Lexicon LX-5 User manual

LX Power Amplifiers
US MSRP:
LX-7 $5,995 • LX-5 $4,995
HIGHLIGHTS
• 200W per channel, each with four custom designed, hand-graded output transistors
• Bridgeable architecture for higher power output (400W at 8Ω)
• Oversized toroidal power transformer with extraordinarily low DC resistance
and thermal protection
• High-power supply voltage (160V) for extra headroom at the outputs
• THX Ultra Certification
• Junction Temperature Simulation (JTS) to provide maximum
performance from output transistors
• Thermal protection against overheating
• Speaker protection against DC and frequencies below 10Hz
• Protection against short circuits, device failures, miswiring, and internal faults
• Stable with mismatched, reactive, or unusual loads
• Quiet, microprocessor controlled, forced-air cooling to minimize chassis size
• Compatible with 2Ωspeaker impedances (INDIVIDUAL Mode)
• Trigger input for power control from an external device
• RCA, XLR, and 1/4-inch Tip/Ring/Sleeve inputs
• Ground lift switch
• Heavy-duty gold plated outputs
• Multi-color channel status LEDs
• Rack-mount option available
LX-7 7 Channels x 200 Watts
LX-5 5 Channels x 200 Watts
