Buffalo III - flexibility without compromise.

See page 30 for the pin layout of the connector.

CCW means counter clock wise.

Thank you, that's make sense with connectors sent by TP

It's the right pin, right?

Hey folks we are getting way off topic. I have deleted some posts and will delete any more. The are other more suitable threads to post about power supply design.

CCW right pin?

Buff 3 build

I have been assembling the buff 3 kit with the sidecar, mux and no volume pot. I cant get a signal lock. The mute led is on always. Jumpers 1-12 installed, switches set off except sw2-8 is on. Jumper to bypass volume control. 75R on mux for spdif. I'm not sure of the input selector wiring, no manual. The input selector changes the leds but no sound or lock.Theres some pics. Any idea what I am forgetting?

 

[merlin el mago]

Have you connected S/PDIF GND? in your pic only see connected the positive S/PDIF...

Buff 3

No I didn't. The guide said not to connect ground on Spdif. Man I'll feel really stupid if that's all it is! I'll try it to now. Thanks.

 

[LeonvB]

The guide said not to connect ground on Spdif.

That is correct. It says you need to connect the SPDIF wires to + and - on the module. For SPDIF you do not use the GND connector on the module.

 

[NicMac]

If it is ordinary S/PDIF I think the manual say to connect the second wire to "-" and not to ground. At least that is how I understood it.
Don't you need to mount termination resistors (R1-4)? I cannot see them even if you write that you are using 75R.
Cheers,
Nic

buff 3

That was it. That's what happens when you work way too late on a kit trying to get it up and running. I thought it was weird to not have a second wire on the Spdif. I am listening to the buff 3 finally. Sounds great. Thanks for pointing me in the right direction. I have the 75r on the bottom of the mux to make it easier to change later. The legato 3 plays fine without caps on the output with the pass labs aleph 30 amp.

CCW right pin?

Finding which pot connection is CCW and which is CW is pretty simple. Just turn the pot completely one way or the other. Then measure the resistance between the wiper and each side. The lowest resistance matches that direction's extent. Easy right?

 

[avr300]

At least, is sounds easy 😉

Is there an eta on IVY availability?

Is there an eta on IVY availability?

My guess would be 23rd October when the TPA guys come back from vacation.

I'm hoping for news on AC2 and the differential I2S line module(s).

Greetings,

completed soldering BIII sidecar and legato.

well, I broke 2 ribben connectors and lost a hex connector

Anybody know the exact replacement parts from mouser.

regards.

 

[beau2317]

I'm interested in any opinions from BIII users as to the exact meanings and effects of some of the switch settings.

I'm only using SPDIF input, mostly red book. So what effect do these settings have, or are they even relevant?

- Quantizer setting
- Differential mode
- FIR Roll off (and what does this filter do exactly?)

Thanks for any input..

 

[necplusultra]

can somebody confirm that this is the replacement part for the ribbon connector for sidecar

thanks.

Something like this would work just fine:

15-44-5820 Molex Headers & Wire Housings

Then just a 2 x 10 2.54mm pitch standard male pin header for the other side.

Here it's what have been confirmed already.
However, you can just use a glue for broken ribbon connector, if you broke a clips in a female.

 

[necplusultra]

sorry Andriy,

my understanding is that your post referal is to connect the sidecar without the ribbon cable directly to the BIII with the female connector soldered to the sidecar.

I'm looking to replace the ribbon connector.

thanks anyways.
