Hello,
I've had the ok from TonyL to answer technical questions!
Raj,
1. what is the USB res, I've red somewhere that its 16/44 will this be at all updated to 24/96?
The resolution is currently up to 48kHz/16bit plug and play. We appreciate this is not up to the computer audiophile high resolutions available on some other units but it was a feature we added at a low cost to the end user that required no license fee or drivers. It does perform extremely well at CD quality with absolutely no jitter related side bands measurable and a near perfect 16 bit noise floor.
The USB input PCB was designed in as an individual module with an spdif output that is transformer isolated before feeding our AES receiver in the same way all the other digital inputs do, so future upgrades of this would be possible if we found what we considered a suitable solution and the demand was there.
2. Is there a IR remote control for the volume?
No, the remote for the unit is available separately and attaches to the HQ via ethernet cable (not ethernet protocol, DC signals only to prevent any spurious tones) and can control up to four units for 7.1 if required. It also has functions for the pro market that are not available on the front panel of the unit for DIM, MUTE, MONO two preset level buttons, individual source select buttons and a dB attenuation readout.
3. What DAC Chip does it use?
We use a pair of Wolfson WM8740s with a few tricks to squeeze the optimum performance from them to get the THD+N of the DAC/PRE to be >100dBFs with full scale input (~0.0006%) at the balanced output. The unit was initially going to use a pair of WM8741s however after a great deal of testing we found the 8740s to out perform the 8741s in what we considered to be certain critical areas, the repeatability of the 8741s was also not as good as we required and the decision was made to use the 8740.
4. Is the output a "real" balanced one?
The output is a differential stage capable of up to +27dBu with 0dBFs input when used balanced, if used unbalanced it will give 6dB lower, i.e. +21dBu (without shorting the unused phase) or on the unbalanced output.
Thanks for your interest, any further (technical) questions, feel free!
Regards, Kieron.
