Allen & Heath DX32 PRIME Input Card
The PRIME Input card is Allen & Heath's premium 8-channel preamp option for the DX32 modular expander, built for engineers who want the extra headroom and detail a standard preamp card doesn't give up. Where most preamps run AC coupled, PRIME uses a DC coupled gain stage that removes the low-frequency distortion AC coupling introduces, so bass and low-mid content stays linear and phase-accurate into the mix engine.
Each channel is hand-trimmed at the factory for common mode rejection, with a matched low-noise quad transistor front end and audiophile-grade capacitors in the signal path. Conversion runs on the latest 32-bit/96kHz ADCs, with four channels of summed conversion per input for extra dynamic range and SNR, and the whole card sits in full metal shielding for RF rejection. It installs in any DX32 slot alongside standard or other PRIME cards, on a dLive, Avantis, or SQ system.
