Overview

The DASK-S704 Sampling Function Software is software specially designed for Sony DRE-S777 Sampling Digital Reverb. Using the DASK- S704, you can sample the reverberation of your favorite acoustic space or plate reverb, and store the sampled data in the Memory Stick TM 1).

Synchronized addition sampling with excellent signal-to-noise ratio

The DASK-S704 uses the TSP (Time Stretched Pulse) signal as a reverb source for sampling. The DASK-S704 repeats the process of D/A conversion of the TSP signal, output from speakers, pick up from microphones and sampling. It adds sampled data to synchronization repeatedly, then samples the average value of the added data. With this method, the more times the repetition is carried out, the more the noise level against the reverb element is reduced, and thus higher the signal-to- noise ratio.

Normally, set the repeat to 16 times. When you perform sampling outdoors or indoors with much background noise, set the repeat to 32 or 64 times. Changing the repeat from 16 to 32 times improves the signal-to- noise ratio by about 3 dB; changing from 16 to 64 by about 6 dB.

Sampling frequency from 44.1 to 96.0 kHz available

You can select the following three sampling modes to match the reverberation of a sampling space.

•Fs/5.5sec: Sampling period of 5.5 seconds with 44.1 or 48.0 kHz sampling frequency

•Fs/11sec: Sampling period of 11 seconds with 44.1 or 48.0 kHz sampling frequency

•2Fs/5.5sec: Sampling period of 5.5 seconds with 88.2 or 96.0 kHz sampling frequency

When you perform sampling in an acoustic space with a longer reverberation time, such as a church, select Fs/11sec. Although sampling is performed for 11 seconds, the sampled data obtained for the first 5.5 seconds is used for compiling.

Note

When you sample/compile with Fs/11sec or 2Fs/5.5sec, you need the optional DABK-S703 expansion DSP.

Storing up to 42 reverb programs in a 64 MB Memory Stick

You can store the sampled or compiled data in the supplied Memory Stick or commercially available Memory Sticks of 16 MB, 32 MB or 64 MB. The data file size is about 2 MB for Fs/5.5sec sampled data, about 4 MB for Fs/11sec or 2Fs/5.5sec sampled data, about 1.5 MB for Fs/5.5sec Fs compiled data and about 3 MB for 2Fs compiled data.

If you store compiled Fs data only, a commercially available 64 MB Memory Stick is capable of storing up to 42 reverb programs.

The supplied Memory Stick has a 24 MB area for storing the sampled/ compiled data.
