Released in 1991
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.
