The quality of the mic pre-amplifiers and the analogue to digital conversion has never been in doubt since the introduction of Horus in 2012, but some of the earlier adopters wanted even more functionality from this remarkable Networked Audio Converter. In many situations, multiple recordings or feeds to front of house sound systems were required and often with incompatible sampling rates. The solution was to provide an additional analogue output after the mic pre and the AD8D and AD8DP offer just that. The standard AD8D replaces the AD8 and allows PCM recording up to 192 kHz. The premium AD8DP replaces the AD8P card that allows extreme recording resolutions of DXD at 352.8 kHz and all variants of DSD up to 256 (11.2 MHz). Both options are shipping now.
The addition of a second 25 pin D-Sub connector was simple enough to create but the preservation of the exceptional fidelity was paramount. The specifications are as peerless as you would expect:
- Frequency response +0/-0.3dB @ Gain 40dB
- THD+N (1 kHz) Mic at G=0dB
- Dynamic Range (flat 20 Hz – 20 kHz)
- Dynamic Range (A-weighted, typ.)
- Max Direct Output level, typ.
- Direct Output Impedance
- 10 Hz – 50 kHz
- < 0.00035%
- > 122dB
- < 1000
Each card also features:
- 8 x exceptionally transparent, Merging designed pre-amplifiers
- Remote/Local switch to Line Level on a per channel basis
- Completely remote accessible for all parameter changes
- Phantom Power/Phase/Low Cut Filter switchable per channel
It is this attention to detail and quite extraordinary digital connectivity that has seen Horus sales accelerate rapidly since its launch. The mere fact that one Horus unit can simplify an installation and replace so many other devices is reason enough for many users, but the real added value comes with the extraordinary sonic performance and ability to interface with virtually any digital or analogue equipment at a remarkably affordable price.
