Re: Scope Classic SPDIF impedance

Are you transmitting from SCOPE as SPDIF, or AES in both scenarios? It seems you are receiving AES, so you should make sure scope is always transmitting AES. Transmitting as SPDIF via Scope 4.5 Classic. I don't have the option for AES since it's not the plus version or XITE. But even if you think a...

Re: Scope Classic SPDIF impedance

A digital signal will not be attenuated in volume if you use the incorrect cable impedance... I tested this by passing a signal through an RCA 50ohm to BNC 75ohm cable and then into the Canare 75ohm BNC to 110ohm AES adapter. The sound is much lower in volume rather than when using just a regular R...

Re: Scope Classic SPDIF impedance

shorter runs won't be affected by a slight impedance mismatch. Just read a post on Lavry's site saying the same thing, that for cables under 2 meters there's no difference between rca/bnc 50ohm and bnc 75ohm connections assuming the cable is thick enough. And this does make sense since a 50ohm resi...

Re: any recommendations for headphone amp?

hey quantum, what's the deal with benchmark dac1s coming with sennheizer hd650? Are they specifically designed for hd650? Very extravagant solution tho.. $1k for just the unit.. No they're not, it's just like a little gift that goes well in terms of ohms. You should go with the old DAC1 and if you ...

Re: any recommendations for headphone amp?

you can get a benchmark dac1 (not hdr or usb) or mytek dac96 for less than $600 and be done with it.

Re: Scope Classic SPDIF impedance

the yellowtec is usb so it should be fine. my digital cable runs are all under 4ft. i have no sound quality issues or dropouts. but since all of my digital chain is aes i'll just get the yellowtec to have a piece of mind, do 192khz, and have the option for soundblade.

[quote="jksuperstar"]Do you see a problem or are you cutting off your legs before trying to walk?

problem is i don't have a pulsar plus with AES or the Yellowtec AES interface yet. but I guess I should've said how does Scope work with other sound cards.

Re: Scope Classic SPDIF impedance

thanks. so if that's true then replacing the breakout rca jacks with bnc would give at least 25ohm higher reading, according to: http://www.diyaudio.com/forums/digital-source/61569-true-75ohm-rca-type-plug-possible.html and http://www.bluejeanscable.com/articles/75ohmrca.htm . right now i have recor...

Re: Scope Classic SPDIF impedance

Is there a way to find out if Pulsar 1 or 2 Classic cards even transmit 75ohm signals or a way to measure this on my own?

Re: Scope Classic SPDIF impedance

Thanks but I have done that already. RCA works better than optical almost always but the problem is that RCA connectors can never be true 75 ohm due to their dimensions, only BNC can be true 75 ohm. So I guess the only way to get a true 75 ohm connection from Pulsar cards is to replace the RCA conne...

Scope Classic SPDIF impedance

So apparently true 75ohm RCA connectors do not exist. BNC are 75 ohm. But since RCA is less than 75ohm, that means that Scope cards (except Plus versions) are not capable of true 75ohm digital output. I wonder is there's a DIY or any other way to change the Classic version to the Plus to gain 110ohm...

Re: Faxi Video: Yamaha An1x Review / Messing Around / Demo

Cool review. Several months ago I bought a new one from 1997. The only thing that sucks with these synths is when you change the cutoff, you can hear the little digital steps, it's not as smooth as other synths. And the only way to get around that is to use the filter envelope. Other than that, it's...

For Windows Vista, 7, and 8. A superb parametric equalizer based on text file editing, the way real audio engineers do it :P It's mostly for home theater usage due to "embedded" integration into Windows, but could be useful for other things. Wanna take out all bass under 120hz and keep you...

Re: PLAY/RECORD plugin?

I guess that's how Cubase recognizes Scope inputs and outs. Remember 32bit is really 24bit. When you are recording music you're recording at 24bits, so that's probably why Cubase is seeing Scope 32 bit sources as 24bits. I don't like or use Cubase. Also, Cubase and Creamware didn't really like each ...

Re: PLAY/RECORD plugin?

But when recording from analog inputs or from asio source ? I don't get why it would be better to record asio source in 32bit than asio 2flt ..? Analog will give you the quality of Scope interface AD converters and has nothing to do with ASIO inputs. ASIO 32bit int is better because no extra comput...

Re: PLAY/RECORD plugin?

Reading this - is the usage of Asio 2-Flt Source (with Cubase, XITE-1) not the best decision? Should i use Asio 2 Source instead, which would (as 32 bit integer) use not so much resources? I know - this question maybe wrong in an development thread, sorry ;) Apparently it's not. It's best to record...
