Emotiva BasX A-800 Multiroom Power Amplifier

The BasX A-800 provides eight separate channels of amplification, which can be used as eight separate channels, or as four stereo pairs, or as four bridged channels, each capable of delivering higher power. A pair of stereo bus inputs can be used to send the same source signal to each pair of channels, or each channel can be fed with its own individual input signal. Flexible triggering options allow the BasX A-800 to be turned on manually, or by a trigger signal from your processor or preamp, or configured to turn on automatically when it senses an audio input. The BasX A-800 is perfect for running multiple pairs of speakers in different locations or rooms, and can provide plenty of great sounding power to run up to four separate pairs of in-ceiling or in-wall speakers in up to four different zones.

Sound Quality First

  • Designed first and foremost to sound great in all types of audio systems with all types of music.

  • Great sounding Class A/B output stage ensures smooth, detailed sound and incredibly natural imaging, without a trace of harshness or strain.

  • Low noise, wide bandwidth design lets you hear everything your high definition sources have to offer.

  • Totally stable with real world speakers in real systems; not just on a test bench.

Solid Engineering And Quality Construction

  • A heavy duty linear power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers.

  • Top quality parts and construction throughout for years of reliable trouble-free service.

  • Heavy steel 2RU chassis with milled aluminum faceplate offers strength and rugged good looks.

  • Double sided FR4 circuit boards with plated-through holes help optimize signal paths and minimize the need for point-to-point wiring.

Flexible Signal Connections and Power Options

  • Unbalanced inputs via industry standard RCA connectors accept all standard unbalanced interconnects.

  • Heavy duty insulated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.

  • Remote trigger input and output allow the BasX A-800 to control and be controlled by other trigger-enabled equipment.

  • The BasX A-800 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and will automatically detect and configure itself for the proper line voltage.

Multi-Zone Capabilities

  • Eight fully independent amplifier channels; each speaker output is powered by its own separate amplifier channel.

  • Bridgeable outputs; each pair of amplifier channels can be independently configured to act as two separate channels, or bridged into a single higher-powered channel.

  • Flexible input options; each pair of channels on the BasX A-800 to receive its input signal from its own independent input, or from the stereo bus input.

Protection

  • Audiophile-grade fault protection is entirely transparent under normal listening conditions, yet protects the amp and your other equipment from virtually all common faults.

  • Full three-year warranty ensures that you’ll be able to enjoy your BasX power amplifier for years to come.

Circuit Topology

  • The BasX A-800 is an eight channel power amplifier, specifically designed for use in multi-zone and whole home applications.

  • Each individual amplifier channel features a carefully designed high current, short signal path, Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry.

  • The eight amplifier channels in the A-800 are arranged to provide the absolute maximum in terms of flexibility: each channel may be used separately, or as part of a stereo pair; each stereo pair may be supplied with its own input signal, or receive its signal from a common stereo input bus; and each pair of channels may optionally be bridged into a single channel with higher power (for a total of four bridged high-powered channels).
