The XPA Gen3 modular power amplifier is comprised of a heavy-duty chassis, which houses the oversized power supply, and up to seven amplifier modules.
The XPA Gen3 can be purchased with anywhere between two and seven amplifier modules installed, and additional amplifier modules may be installed as more
channels of amplification are needed (up to a maximum of seven modules). The front panel display and protection system are designed to work with the
maximum number of channels, and so need not be updated when the XPA Gen3 is expanded; on the rear panel, slots not occupied by amplifier modules will
be covered with protective cover panels.
Note: To ensure that additional amplifier channels are installed properly, and function to our specifications, additional amplifier modules must be
installed by Emotiva, or by your local authorized Emotiva service representative.
A Word About Power Ratings
Music is, by its nature, dynamic. While it’s relatively common for the two main channels in a stereo amplifier to be asked to simultaneously deliver high
power levels, it is very uncommon for more than two channels to be called upon to deliver high power continuously at the same time, and this almost
never occurs outside of laboratory test conditions.
In order to deliver the most dynamic performance where it counts - with real music - we have designed the XPA Gen3 modular power amplifier with a
single immense power supply, which is able to deliver massive power continuously to any two channels, and to deliver huge amounts of power dynamically
to any number of channels when and if called upon to do so.
The power ratings for the XPA Gen3 modular power amplifier are the same with both channels driven continuously in the two-channel version of the amplifier,
and for ANY TWO CHANNELS DRIVEN CONTINUOUSLY in the versions of the XPA Gen3 configured with three, four, five, six, or even seven output channels.
In addition to this, because we always aim to provide the most complete information possible, we have also rated the other versions in terms of continuous power
(under laboratory conditions) with all channels driven.
Also note that, while the exceptional sound quality of the XPA Gen3 modular power amplifier, and its two-channel continuous power rating, remain the same
whether you choose to use a 120 VAC line or a 230 VAC line, the multi-channel power ratings are somewhat higher when you power the XPA Gen3 from a 230 VAC circuit.
While the XPA Gen3 modular power amplifier will provide plenty of power for most home theater installations when run from a 120 VAC line, for the absolute
best possible performance, we recommend operating the XPA Gen3 from a 230 VAC line.
