Усилители мощности стерео — Emotiva XPA-9 Gen3

The XPA-9 Gen3 is a nine-channel power amplifier from Emotiva, built with the same exceptionally wide rated bandwidth as the XPA-5 Gen3 across considerably more channels. This model represents Emotiva's largest current multichannel amplifier, suited to elaborate object-based surround installations needing numerous amplified channels from a single chassis.

Key specs that matter

Input sensitivity is 1710 mV, matching the XPA-5 Gen3. Rated output is 300 W into 8 ohms per channel pair, rising to 490 W into 4 ohms when measured two channels driven. Rated bandwidth is 5 Hz to 80 000 Hz, matching the XPA-5 Gen3. Signal-to-noise exceeds 115 dB. Maximum power consumption is a substantial 2600 W, reflecting the considerably greater number of channels this model drives simultaneously. Damping factor exceeds 500. At 432 x 203 x 483 mm and 24 kg it is heavier than the XPA-5 Gen3, consistent with the additional channel count housed in a similar footprint.

Sound and use context

Expect the same highly controlled, wide-bandwidth character as the XPA-5 Gen3, extended across nine channels for an elaborate object-based surround system - a considerably more capable performer than any conventional AV receiver's built-in amplification for the most ambitious home theatre installations.

Pairing

Nine channels cover even elaborate Atmos or DTS -X layouts without needing external amplification for additional positions, considerably simplifying a complex multichannel installation.

Alternatives

Emotiva's XPA-5 Gen3 sits below this model with fewer channels for a more modest surround system, worth considering instead if a nine-channel layout exceeds what a specific room's speaker configuration requires. Given the exceptional 2600 W maximum power consumption here, checking the available mains circuit capacity in the installation room is a sensible precaution before the unit arrives, particularly for a system running all nine channels simultaneously at demanding listening levels. Adequate ventilation space around this substantial chassis is essential for reliable long-term operation. Overall this remains Emotiva most ambitious current multichannel choice for elaborate surround installations. A dealer visit remains the simplest way to compare this model against the smaller XPA-5 Gen3. A dedicated or adequately rated mains circuit is worth confirming given the substantial power draw here.
