Sony DPS-R7 Reverberator

The Sony DPS-R7 was the first in a new digital effects line up from Sony, its success spawned a number of other effects using the same architecture as the DPS-R7. The Sony DPS-R7 is an excellent digital reverb that still stands up today, with its full bandwidth and excellent reverb algorithms, it is hampered only by its truly awful interface if you wish to program it.

Sony DPS-D7 Digital Delay

On the back of the success of the Sony DPS-R7, Sony developed and released the next processor in the line-up, the DPS-D7 Digital Delay with audible improvements. Sony didn’t just add in the new algorithms and release it, they also chose to make the DPS-D7 use a higher sampling rate of 48kHz to improve the bandwidth even further than the DPS-R7.
