The PRIME Input Module is a completely new Allen & Heath preamp design at the leading edge of audio tech designed to get the most in audio performance from your dLive, Avantis, or SQ.
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.
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 LF distortion 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.
Linearity was paramount in the design process, so Allen & Heath designers 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.
To further preserve signal integrity, the PRIME circuitry is encased in full metal shielding for increased RF rejection throughout the signal path. Finally, before a PRIME Input module leaves the factory, each unit has its individual preamps trimmed by hand to meet Allen & Heath's exacting requirements for feedback path and common mode rejection.
