juliocat Posted August 3, 2018 Share Posted August 3, 2018 The katana comes with a cable to connect 1 power supply, just 2 wires, one red positive one black negative to a 5 volt 3 amp power supply.

ALLOaudio Posted August 16, 2018 Author Share Posted August 16, 2018 @maxijazz @Panelhead as of now there are 2 acrylic cases available for the KATANA 1> player (RPI + KATANA stack) 2> player + isolator ( RPI + KATANA stack + Isolator v1.2) we are also working on an alu case which will take some time. Currently , we are not offering XLR connectors so we cant design a case without knowing what connectors everyone uses. As for the relay att, we can surely design it... please contact me when ready to order and will work on it. As you may have seen on the site, we have released a notice : The Katana is a complex DAC that offers multiple filtering and powering options.The pursuit of the best sound quality is what drives our design team and the reason behind our recent decision to halt manufacturing of the late KATANA. A new version, the 1.2, is in the works and will only have a few components changed resulting in a subtle, yet necessary SQ improvement. Please note the following: No orders will be accepted for the next 14 days. Already received your KATANA? A new one will be sent to you once the K1.2 is released. Already placed an order ? You will be soon contacted by our customer support team. Thank you for your understanding. technically ... We improved the LPF on summing opamp. Small improvement in SQ We improved filtering before analog stage . Medium improvement in SQ We improved noise escaping DC/DC convertor. Not quantified yet We connected earthing to board (with Nirvana PSU it will be automatic). Removal of some HF and better trebles . I would say small improvement but clearly audible Adding some 220uF caps to analog stage. No improvement KATANA 1.2 is being finalized and ready to ship by the end of the month. will update soon.

Regards Andre Does the dac have galvanic isolation? Also can you consider making an optional usb cable available that has a double shield? There is a lot of talk on this site for those that DIY, that this really improves the SQ? Link to comment

ALLOaudio Posted August 20, 2018 Author Share Posted August 20, 2018 @beerandmusic the isolator board offers galavanic isolation. cables are very touchy subject, most people get theirs from other sources. @pjmcos no at all. @Panelhead and others... thanks for your patience. Link to comment

Do you mean you mean galvanic isolation is an option you can buy or that it is included? Link to comment
Cortes Posted August 24, 2018 Share Posted August 24, 2018 This is a bit silly, but what are the inputs for the Katana player?. In what ways can it be used. I get fooled looking at the pictures. 1. Ethernet -> Katana?. 2. laptop USB -> Katana?. 3....? Link to comment
seeteeyou Posted August 24, 2018 Share Posted August 24, 2018 None of the above, it's made exclusively to accept the I2S output of Raspberry Pi in addition to an upcoming isolator from Allo. Link to comment

ALLOaudio Posted August 27, 2018 Author Share Posted August 27, 2018 @Cortes the KATANA receives the music from the RPI and outputs RCA and XLR. the input is done on the RPI who received the music stream via ethernet and then transmits to the KATANA by I2S through the 40 pin header. Link to comment
juliocat Posted August 30, 2018 Share Posted August 30, 2018 Hello ALLOAudio What is the optimum voltage for the Opamp Section?? i know the board say +-15 volts Hackintosh I7 16GB Ram, Roon, HQPlayer, Drobo 8 TB NAS, Raspberry Pi 3 NAA, Gustard X20 ES 9018 Xmos, Audio GD C39 Preamp, The First ONE DIY Amp, Monitor Audio GS20 Speakers, Monitor Audio RSW12 Subwoofer, PI Audio MagikBuss filter.

GrahamJohnMiles Posted November 10, 2018 Share Posted November 10, 2018 The ‘wait another 14 days’ seems to be stretching out into weeks. Would be interested in ordering, but still not ready for sale on the website. Can we get an accurate estimate as to when it will be ready for purchasing? Link to comment
astropuppy Posted November 20, 2018 Share Posted November 20, 2018 Our the Katana's currently available on the allo website version 1.2? https://www.allo.com/sparky/katana-player.html Link to comment
cantonna7 Posted November 22, 2018 Share Posted November 22, 2018 The Katana has XLR output? Read some reviews, the power input seems a bit complicated, so many options and power on sequence .... Link to comment
Not_really Posted November 27, 2018 Share Posted November 27, 2018 1. Yes, but you have to solder it yourself. You can use both outputs at the same time according to allo.com. 2. Turning on can be complicated or easy. I use two of their SMPS via USB-C (Isolator and Controller). Then you can turn it on without any problems at the same time, also via switch socket.

Doc_sonic Posted January 26, 2019 Share Posted January 26, 2019 I run my new Katana's balanced outs to my power amp and RCA outs to my sub woofer, both on together. I use two SMPS via USB-C (Iso & Cont.) too. Sounds so good - it seems alive... Link to comment
