Monolith 5X 5-Channel Amplifier

The Monolith 5X is a new 5-channel power amplifier rated at 200 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. It delivers full bandwidth power from 20Hz to 20kHz with all channels driven. The Class AB design provides high current capability without limiting or protection circuitry in the signal path.

Ideal for Demanding Home Theater Systems

This amplifier suits owners of difficult-to-drive speakers who need sustained high power across five channels for dynamic movie soundtracks and music reproduction. The greater than 120dB signal-to-noise ratio ensures quiet passages remain clear. It is not suited for installations requiring more than five channels of amplification or for users needing integrated processing, streaming, or room correction features.

200 Watts Per Channel Continuous Power

Each channel comfortably handles demanding speaker loads down to 4 ohms with 300 watts available per channel. The design maintains current delivery even when speaker impedance drops significantly. Headroom runs out when a system requires six or more amplified channels, or when the preamplifier or processor lacks balanced XLR outputs to match the amplifier's input configuration.

Questions about this item

What pre-amp or processor with XLR outputs do I need to drive the Monolith 5X?

You need a pre-amplifier or AV processor that provides balanced XLR outputs for each of the five channels you intend to amplify.

Can I keep my current 8-ohm speakers when adding the 200-watt Monolith 5X?

Yes, the amplifier delivers its rated 200 watts per channel into 8-ohm loads across the full 20Hz to 20kHz bandwidth.

How can I verify the Monolith 5X is delivering its rated 120dB signal-to-noise performance after setup?

Play a silent passage at your normal listening level; any audible hiss indicates the noise floor is higher than the specified 120dB ratio.
