For those looking to get the highest levels of audio performance from their dLive, Avantis or SQ, we've created PRIME, two new modules for use with DX32 expanders.

The PRIME Input Module is a completely new Allen & Heath preamp design at the leading-edge of audio tech.

Using the very latest converter technology and ultra-linear components combined with meticulous design, the PRIME Input module lets you exploit the full potential of our 96kHz XCVI FPGA core, delivering next-level audio quality for critical live, broadcast and studio applications.

Available as 8-channel cards for mounting directly into a DX32, you can create the configuration you require, whether it's for a handful of critical 'money' channels, or a whole orchestra section.

What makes it so good? Using years of experience in combination with ultramodern technology, we believe we've redefined transparency, slashing THD and vastly improving noise performance, while ensuring wickedly fast slew-rates for incredible transient response.

PRIME Input technology

With an ultra-flat frequency response from 1Hz all the way up to 40kHz, and an incredibly fast slew rate, PRIME delivers detailed and articulate audio to the mix engine at the highest possible resolution with breath-taking transient response, and full range linearity.

While most preamps are based on AC coupled stages, PRIME has a DC coupled gain stage which eliminates the capacitive feedback typical of AC coupling, vastly improving low frequency linearity and phase response. This unique design calls for painstaking component choice and layout in addition to intensive per channel component trimming during commissioning.

Ultra-linear design and components

Because linearity was paramount in the design process, our design team made several innovations to improve high input level handling. A super-matched low noise quad transistor package on the front end dramatically reduces thermally induced very low frequency anomalies.

Audiophile grade Nichicon FG (Fine Gold) electrolytic capacitors – manufactured using state of the art etching techniques – have been utilised in the signal path.

Naturally, PRIME employs the very latest 32bit / 96kHz analogue-to-digital converters, but more importantly, the design team used several devices in parallel on each channel to reduce distortion and optimise noise and dynamic range. 8 channels of analogue-to-digital conversion are employed for every pair of input channels yielding increased headroom and superior SNR compared to standard AD implementations. 

The ADC system can also be user configured for anti-aliasing roll-off characteristics: either fast or slow roll-off and ultra low latency delay, the sound engineer can pick optimal settings for particular applications or music.
