Geek Pulse: Geek desktop DAC/AMP by Light Harmonics

[haquocdung]

Hi, is there anyone keep a copy of the latest driver can share?
I think the lhlab website it down permanently and I can't find it anywhere.
Thanks.

I have lps4 and was wondering if anyone knew how much DC it can output. I am considering powering the cavalli cth with it but want to make sure it would work. Cavalli cth is 28V DC and 1.25a whereas the geek lps4 has a slot for 1.2a but idk about the 28v

 

[m-i-c-k-e-y]

All four connectors are 12V. USB type A (USB DAC) gives 5V @ 500ma

Here were some old notes I had...

LPS4 outputs

Geek LPS4:
This is just like Geek LPS, but it has four 12 volt DC outputs instead of just one.
It's perfect for other audio gear you might have that uses 12V DC power.

0.5 A
1.2 A - Pulse Xfi +N+T + DAC upgrade
0.5 A - Pulse Tube HPA
1.2 A - Pulse Tube HPA


Pulse Headphone Amplifier comes with low noise 12VDC switching power supply.
And we recommend you use Pulse HPA and Pulse Tube HPA with our Geek LPS4.
Pulse HPA needs one 1.2A 12V output from LPS4.
And Pulse Tube HPA needs one 1.2A 12V, one 500mA 12V output from LPS4.

Gotcha, thanks for the quick responses. Looks like it's definitely not enough for the 28V needed. Back to being a paperweight it goes!

Mine I am using the 12V 1.2A to power my Android device (as source/streamer via UAPP). The 5V to power my USB regen/reclocker.

I found a Benchmark DAC1 in good condition for a moderate price, has anyone compared it to the Geek Pulse Sfi or something similar?

 

[greenkiwi]

I used one for quite a while, I think that how moderate the price was, would really determine whether or not it was worth it.

I will say that the Benchmark DAC1 I was using is still functioning without issue for my brother, which the same cannot be said for many many Geek Pulses.

If it were me, I'd probably be looking for a newer DAC. The DAC 1 came out in 2005 or so.

I was just given a geek pulse, its on the final versions of the firmware but the 3.26 driver install fails on a windows 10 laptop because of an error.

Hi, what was the error - and did you do the install without the Geek Pulse attached via USB? Try uninstalling the 3.26 and reinstalling it - after a fresh reboot and without the Geek Pulse attached - until the Driver installation asks for it. You may need to look in the Device Manager settings of the Windows 10 Control Panel to do the uninstall in several different listings, including Sound Devices.
Some other notes below for a Music Bee utilization. Some of it may be relevant to your Foobar setup:
The newest driver (3.26) works only with a workaround: Otherwise Music Bee just shows a BASS_ERROR message when play is attempted.

1. In the Sound Control Panel, Speaker Geek Pulse Xfi must be set as Default Application.
2. In the Geek Plus Xfi Properties, in Advanced Tab, the Default Format needs to be set to 16bit, 44K and in Exclusive Mode, the first box "Allow applications to take Exclusive Control of the Device" needs to be checked. 2nd Box works unchecked - status if the box is checked is unknown
3. All changes to the Geek Pulse Xfi have to be done outside of Music Bee. Computer has to be shut down, USB Cable removed, changes made, computer reboot. After Xfi changes made, plug in the USB cable before Music Bee startup. Plugging in the USB port from the already on Geek Pulse xfi apparently loads its settings into the driver as the USB port is recognized
4. If the power goes out on Geek Pulse xfi, you may have to first change the 96K to 44K setting, by trying to run a file in Music Bee. This will change the display to 44K, if that is the default setting in the Sound Control Panel Geek Pulse Xfi driver. See 2) above. Once the setting changes and all other changes on the Geek Pulse xFi are reset, then reboot and go to Step 3.

Thanks. The reliability issue is what really bugs me. I have been lucky so far, my Sfi is still working after all these years, but apparently this is the exception, not the rule.Who knows when my luck will run out? The item in question is on offer for 350 Euros, about $400US. Yes, the DAC1 came out in 2005, but was discontinued in 2011, so it is not that old. Just out of curiosity, did you ever make a comparison with some Geek Pulse?

 

[greenkiwi]

Unfortunately, I didn't have them both at the same time. My brother has the BM and I have had the pulse XFi. My current DACs are a Chord Mojo and Hugo 2. ( I can definitely recommend both of them.)

If it were me, I'd probably get a newer dac. 2011 is still 10+ years old at its newest.

Hi everyone I wanted to know is this separate power supply compatible with the dac light harmonic geek pulse please?

and if so take which model which voltage?
