Do All SB's Upsample to 48k?

Fri Apr 24, 2009 5:49 am

Just got a new Cambridge Audio Dac Magic -- sounds just wonderful. When my SB 500 or 1000 are connected via coax, the Dac shows a 48k input signal. When the usb input is selected, the input signal is 44k.

I thought it was only the 1001 that upsampled to 48k and was therefore to be avoided if you wanted optimal digital output.

Can anyone else confirm the digital output frequency of their M500 or 1000?

Thanks.

The M1001 should force to 48kHz

The old tubes (M500, M1000, M2000) should pass the music as it's ripped (SAMPLE RATE - Supports (kHz): 8.0, 11.025, 12.0, 16.0, 22.05, 24, 32,
44.1, 48.0
).

Hopefully someone can confirm, Matt

I have my SB 500 connected optically to an SP/DIF-AES converter. The input signal is 44.1k playing HotMixRADIO for example. But you may be playing material with a sampling rate of 48k. Try some internet radio stations, most use 44.1k.

Just my $0.02...

Nope - 48k no matter what

Thanks for the responses. I get a 48k output on the coax out no matter what I play - internet radio or my own music library.

I'm using a M500 (updated to a M1000 screen by Matt) and have seen the same behavior with a "stock" m500.

Any idea about what might be going on?

Thanks!

Is it possible that your UPNP server transcodes the sample rates?

Thanks for the idea. Where would I check this? I use iTunes to serve music.
