Page 7: Design Features
DESIGN FEATURES Precision-machined chassis, milled from a solid block of MACHINED ALUMINUM CHASSIS: aircraft grade aluminum, provides exceptional thermal heat transfer/dissipation, RFI/ EMI shielding, resonance control, and minimizes micro-phonically induced micro- vibrations from any source. Critical audio circuits are implemented on mil-spec, multi- CERAMIC CIRCUIT BOARDS: layer, low dielectric constant, Rogers™... - Page 8 CE approved speaker output terminals require no tools for secure, low BINDING POSTS: resistance connections. Illuminated front panel push-button switches the FRONT PANEL STANDBY BUTTON: amplifier into standby mode (<0.3 watt consumption). An internal switch allows the user to dim the front panel indicator light "ring" or shut off the light altogether when the amplifier is powered on.
