DSP24 - FAQ answers

On this page are answers to some of the most common questions we receive about the DSP24 PCI-card.

DSP24 specific topics

Back to software and usage related questions



1. What kind of ADC and DAC is used on the DSP24 PCI-card?

The ADC and DAC is represented by an 18bit SigmaTel AC-97 codec (Internal Mixer). External ADC/DAC units can be connected via the 44pin H-BUS connector, S/PDIF (optical + coaxial) or AES/EBU.

2. Can I record and play with 24bit/96kHz?

The playback / recording via the 44pin H-BUS connector, S/PDIF (optical + coaxial) or AES/EBU can be done with any standard sample- and bitrate up to 24bit/96kHz. The playback and recording via the analog I/O connectors (Internal Mixer) supports up to 16bit/48kHz.

3. If I play a signal via ASIO or GSIF, I cannot hear it. My speakers are connected to the analog Line-Out on the card.

The Line-Out on the PCI-card (as well as the two internal analog inputs, the Line-In and the Mic-In) is actually part of an additional soundcard which has been 'added' to the DSP24 (we call it Internal Mixer). You can use the this section to play Windows sounds or the metronome from a sequenzer, also you could use it for consumer applications such as games or speech recognition software. Since the Line-Out even supports DirectSound, you can use it also for some conventional software synthesizer applications. To control this section, you can use the Internal Mixer / Windows Mixer (SNDVOL32.EXE).

To monitor the signals from your ASIO / GSIF application, you need to use the digital I/O connectors (S/PDIF, AES/EBU or the 44pin H-BUS interface). The DSP24 PCI card alone -without any ADC/DAC unit- works as a high quality digital I/O interface and cannot be used as recording card with high quality analog I/O. The alternative would be either an external box like the ADC&DAC2000 or to use a DSP24 Value rather than the DSP24.
