Clean side accept more than 5V but for heating pourposes better to stay under 9V I think the best will be a 6,4V LiFePO4 battery. Matt "I want to know why the musicians are on stage, not where".

allo.com Posted August 31, 2018 Share Posted August 31, 2018 Its a cheap SMPS , we don't have any exact measuring , but from what I remember its not so bad. About 2.8mV noise ripple at 2A Link to comment
steklo Posted August 31, 2018 Share Posted August 31, 2018 Hi, I'm looking for a good PSU solution for RPi / Digione signature as well. I could imagine that a battery PSU like Ciunas ISO-PS with dual 7V outlets might be a good choice: https://www.ciunas.biz/product-page/iso-ps As I was told the 7V outlet is free from any regulator; that means the full current delivery is available directly from battery. As the clean input of Digione signature can take any voltage from 5V to 29V, one could that way take full advanage of that direct-out-of-battery-approach. The second 7V outlet of the ISO-PS could be used to feed a LT3054 LDO regulator set to 5V output and then feed the dirty side of Digione (and through that at the same time RPi). Nice LT3045 boards: http://www.ldovr.com/product-p/lt3045-a.htm https://www.mpaudio.net/product-page/sd-hpuln-ps (The 5V outlet which Ciunas also offers is regulated by XRP6272 which has 2% output voltage accuracy; that is why I think LT3045 might do a better job) But – the two outlets of the battery are not galvanically isolated! John Kenny (Ciunas) says this doesn't matter as any noise introduced from one outlet would get lost within the large capacity of the battery and therefore would never be apparent on the other outlet. What would you think about that? Best regards Stefan Link to comment
allo.com Posted August 31, 2018 Share Posted August 31, 2018 Hi Stelko you need to respect the current specs of DigiOne Sig. Dirty side needs 2.5A. LT3042 from the link you provided shows a max of 1A Furthermore.. the dirty side does not care much whats feed to it. I would recommend a cheaper SMPS for dirty side and a battery like you have (7V is fine) for the clean side. Link to comment
olklei Posted August 31, 2018 Share Posted August 31, 2018 I have a question regarding my DigiOne SiG. It arrived and seems to be working. However it does not look like the pictures on the allo webpage. It has a strange soldering near the diode sign (see pic.) Is this how it should be? Link to comment
allo.com Posted August 31, 2018 Share Posted August 31, 2018 Yes , DigiOne Sig has 2 diodes and we decided that one will be removed. (it works with both but voltage drop is lower with 1 diode only that you can find on second board) Link to comment
TAV Posted September 1, 2018 Share Posted September 1, 2018 Will an aluminum case be available for the Signature at some point? Link to comment
Johnjc Posted September 1, 2018 Share Posted September 1, 2018 Just to let people know got the signature up and running I am feeding the dirty side with the supplied SMPS I might experiment later on as I have a spare battery I can use and could use a 12v to 5v dc converter Just need to find on with a USB C output or perhaps a adapter Sound wise it is a nice step up. The tonal colour is more richer, it gives more slam and micro detail. Both files and Spotify sound excellent. I need to come up with some way of powering them both up at the same time DigiOne with custom PSU (Supercaped) Coherent Audio Meicord Ethernet Cable IFI USB Silencer x 2Caiman SEQ modified by Coherent Supercaped Amps 2x Philips Black Tulips 370 (one per channel) for PRV drivers.

alastr Posted September 2, 2018 Share Posted September 2, 2018 would the clean side work with 3.3V PSU? am I getting it right that if ordered from Europe, there is no option of pre-installed software? thanks, alex Link to comment

The Ciunas devices use LiFePO4 batteries. These deliver voltage output of 3.2/3.3V or multiples of these voltages. I am wondering how they can claim an output of 7V without any regulator.

Cortes Posted September 2, 2018 Share Posted September 2, 2018 @ALLOaudio Is it possible to use the Digione Signature and Katane with Tinker board instead of Pi board?. Link to comment

We think we have the best jitter measurements.Compared with ANY hardware from any manufacturer. I'll wait for Darko, Hans Beekhuyzen, or Jay Luong reviews.

Johnjc Posted September 3, 2018 Share Posted September 3, 2018 I know the USB bridge quite well and whilst I think it a bit better than the DigiOne, the Signature is in another league for sure.

Johnjc Posted September 3, 2018 Share Posted September 3, 2018 I am pretty sure Allo would not miss the opportunity to upgrade that USB bridge to a Signature version.

nbpf Posted September 3, 2018 Share Posted September 3, 2018 2 hours ago, matthias said: Both compared with the same DAC. Matt But in order to compare USBridge and DigiOne with the same DAC, you have to use a USB to SPDIF interface between the USBridge and the DAC which makes the comparison a bit pointless. I would rather compare the DigiOne with other transports with SPDIF outputs. Link to comment
