Anthem AVM-90
15.4-channel home cinema preamplifier compatible with Dolby Atmos and DTS:X, with automatic calibration and integrated network streaming.
Description
The Anthem AVM-90 is a home cinema preamplifier designed to drive an extensive multichannel installation, up to a 15.4 configuration. It sits upstream of separate power amplifiers and centralises the audio and video processing of a complete home cinema system, handling both the decoding of soundtracks and the distribution of the signal to the various zones or speakers.
Its frequency response extends from 20 Hz to 35 kHz with a tolerance of +0/-0.5 dB, and up to 80 kHz with a tolerance of +0/-2 dB, reflecting faithful reproduction across the entire audible spectrum and beyond. The 110 dB signal-to-noise ratio guarantees a particularly quiet background, allowing the finest nuances of soundtracks to come through without perceptible background noise. On the decoding side, the unit supports the immersive Dolby Atmos and DTS:X formats, as well as a wide range of older playback modes such as Dolby Pro Logic IIx and IIz, DTS Neo:6, Dolby Virtual Speaker and Dolby Digital EX matrix decoding, allowing the sound rendering to be adapted to various sources and speaker configurations.
With dimensions of 431 x 152 x 364 mm and a weight of 10.1 kg, the AVM-90 fits into a standard hi-fi cabinet while retaining the robustness of a dedicated preamplification unit.
This preamplifier is aimed at home cinema enthusiasts wishing to build an ambitious multichannel installation, with a number of channels and a wealth of decoding formats suited to a dedicated room or a scalable system paired with external power amplifiers.

What to check before buying used
On a preamplifier of this complexity, it is advisable to test every HDMI input and output as well as the various audio channels to ensure that no firmware or decoding chip bug has developed over time. The RCA/XLR connectors and sockets deserve a visual check, as does the proper functioning of the remote control and the display screen. Checking correct WiFi and Bluetooth pairing, as well as any available software updates, helps confirm that the network functions remain fully operational.
