RME HDSP 9652 [23/75] Operation under asio

User's Guide HDSP System HDSP 9652 © RME

It often makes sense to monitor the input signal or send it directly to the output. This can be

done at zero latency using TotalMix (see chapter 24).

An automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol

with our ASIO drivers and all ASIO 2 compatible programs. When 'ASIO Direct Monitoring' has

been switched on, the input signal is routed in real-time to the output whenever a recording is

started (punch-in).

13. Operation under ASIO

13.1 General

Start the ASIO software

and select ASIO Ham-

merfall DSP as the audio

I/O device. The 'ASIO

system control' button

opens the HDSP Settings

dialog (see chapter 11,

Configuration).

13.2 Channel Count under ASIO

At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,

so the number of available channels per port is reduced from 8 to 4.

Please note that when changing the sample rate range between Single and Double Speed the

number of channels presented from the ASIO driver will change too. As some channels are

removed, SPDIF and AES move up in the list. This may require a reset of the I/O list in the au-

dio software, and will require a reassignment of the channels within the project.
