Emotiva BasX A5+ Five-Channel Power Amplifier

Real power for the speakers that do the hard work.

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, and a system that stays composed when scenes get loud.

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
