BasX A5+ Five-Channel Power Amplifier

Name: BasX A5+ Five-Channel Power Amplifier
Brand: Emotiva
SKU: EMOTIVA-BASX-A5-FIVE-CHANNEL-POWER-AMPLIFIER

Model AMP-BASX-CHAN-A5+ · Series BasX

The BasX A5+ Five-Channel Power Amplifier adds dedicated amplification to your main home theater speakers: left, center, right, and surrounds. That takes the load off your receiver, so it can focus on processing and control instead of trying to power everything at once. The payoff is cleaner dynamics, clearer dialogue,

Overview

Real power for the speakers that do the hard work.

The A5+ is rated at 95 watts RMS per channel into 8 ohms (20 Hz to 20 kHz, all channels driven, THD < 0.02%). Inside, a fully discrete Class A/B output stage and a linear power supply with a heavy duty toroidal transformer deliver stable, confident power without sounding edgy or strained.

The major BasX Plus upgrade is connectivity. The A5+ includes balanced XLR and unbalanced RCA inputs on every channel, so it pairs easily with everything from traditional AVRs to fully balanced processors. If your gear supports XLR, it can help keep things quieter, especially with longer cable runs. If not, RCA has you covered.

Built-in protection guards against common fault conditions, 12V trigger connections make system power control easy, and the A5+ is rated for 8 ohm speakers while supporting 4 ohm operation.

Common uses:

Power a full 5.1 system with a processor or an AVR with PRE OUTs

Upgrade an AVR by powering the main five speakers for more headroom and control

Drive LCR plus surrounds and let your AVR handle height channels

Features

Five Channels of Clean Power
The BasX A5+ delivers five channels of dedicated Class A/B amplification, rated at 95 watts RMS per channel into 8 ohms (20 Hz to 20 kHz, all channels driven). The payoff is better control and cleaner dynamics when your system gets demanding.
Balanced Inputs Included
Every channel includes both balanced XLR and unbalanced RCA inputs. If your gear supports XLR, it can help keep noise down, especially with longer cable runs. If not, RCA gives you easy, universal compatibility.
Toroidal Power Supply
A linear power supply with a heavy duty toroidal transformer provides stable current delivery. That helps bass stay firm and keeps loud moments sounding clean instead of strained.
Easy To Connect
Audiophile grade 5-way binding posts accept banana plugs, spades, or bare wire. Trigger input and trigger output make it easy to have the amp turn on and off with the rest of your system.
4-Ohm Capable
Rated for 8 ohm speakers with a minimum load impedance of 4 ohms, the A5+ works with a wide range of real-world speakers. Built-in protection guards against temperature issues, shorts, ground faults, and other common fault conditions.
