I had a chance to hook one up via OTG cable to my Nexus 7 (running UAPP app) at the NYC meet on Saturday but I was not able to get the USB sync, most likely due to the power needed to run the GO1000.

 

Anyone have the specs or a link to them for the GeekOut family of devices?


Just going by the power output, it needs to be running close to 1A at peak power. For a low powered device like a tablet you are going to be better off with a self powered DAC/Amp like the Leckerton or Fiio, IMO.

2. How do you engage the awesomeizer (Windows)?

Hold both buttons down simultaneously. Can't vouch that it actually works.

 

Speaking of Windows, has anyone gotten the Geek Out and/or the Light Harmonic Control Panel to indicate an output stream greater than 44.1 khz? If so, how?

One can potentially use a Y-split OTG cable, where there is a USB plug to connect to an external battery pack (or even wall power supply of 5V for phones) to power the GO.  That way, it is getting the signal from the Android device and getting power from the battery pack.

 

There is also the option of placing a powered USB hub after the OTG cable, and the GO is connected to the hub.

 

Either options make the setup less portable; but it will be fine for quick desktop use without resorting to a computer.

NICE ONE!!

Mike, I'm assuming that means you have the iUSB too? Please let us know what you think. Your GO is probably well past burn in and thus offers a good baseline to detect any differences between clean USB power vs straight out of the USB port.
It'd be great news if the performance of the already amazing GO can be taken levels higher. And not to get too far ahead of myself, I can't help but salivate in anticipation of the GO + LH LPS pairing.

Then will be superceeded by Geek Pulse Xfi + LPS pairing. :o2smile:

yes, and I have a OTG Y cable on order.

 

has LH published anything on power drain?  does it ship with a spec sheet?

It doesn't (can't) draw that much.  It was designed to plug into computer USB ports which are usually limited to a max of 500ma.  I am sure at one point I saw the actual figure that it drew, but I can't remember which forum and which thread.   Info is spread all over the place.  I want to say 400ma, which is probably too high for an Android device that hasn't been deeply modded (I think kernel level) to allow such a discharge rate.  I'm being naughty, though and reporting numbers that I am not sure of.

 

For those who really want to use the GEEK Out with portable devices, LHLabs is working hard on the GEEK Aria which will come in two forms: basically a GEEK Out with battery that connects to a phone, or as a full DAP with a crap-ton of storage space for all those DSD files.  No word on pricing or availability, but I am looking forward to the GEEK Out with battery variant to use with my Note 2.

Looks like Larry H has changed the name of this product to be Geek Wave a couple days ago.
Forums on LH labs shows this name in a thread.

Unsure when it will go up on Indiegogo or Kickstarter.

I have the LPS coming too, so I will be able to add that to the comparison I already have cooking with the iUSBPower, and Vaunix Lab Brick.

Oops.  I don't spend as much time on the LHLabs forums because it feels like most of the posts are either outrageous suggestions/demands for possible product features, or the same questions/complaints over and over again (where's my stuff?!?).

At 1000mW x 2 @ 16 ohms, you are at > 0.35A. There is no way that device is 100% efficient, so lets say 0.5A. That is just for the amplifier section, then there is the rest of the electronics. You could reasonably expect it to run at lower current, but it won't reach full power output (which most people aren't likely to care about anyway)

I had no load at all on it, and it could not get enough power to get usb sync to a nexus 7 via otg cable.

A meridian explorer works fine with the same setup.

i find their forums to be the most confusing i've ever run across.

i can never find what i'm looking for.

maybe it's me?................but i think not

To answer my own question and assuming others than myself find messing around with Windows drivers a less than transparent experience:

 

Regarding the Light Harmonic Windows Driver v2.20.0 output bit streams, after poking around and wasting time I discovered that, at least with the KORG, JRiver and Windows Media  players, you have to manually set the sample rate and word depth.  This setting is in the Windows ControlPanel/Sound/Advanced/Default Format pull-down. Whatever Default Format sampling rate is set will be reflected in the Light Harmonic driver Control Panel Current Sample Rate window and on the Geek Out lights (neither, however, show word depth, 16/24). Note also that 24 bit word depth is not yet available in the pull-down table for 88.2 khz and 176.4 khz sample rates.

From what I understand, you only need to meddle with the Sound control panel if you are outputting via DirectSound.  If you go WASAPI or ASIO in your player, then the Sound control panel is bypassed and thus not important.  You can set the bit-depth and bit-rate in your player or ASIO control panel.
