Advanced DSR series active loudspeakers combine proprietary 48-bit digital processing with progressive audio technology to deliver precision integral digital tuning, "D-CONTOUR" intelligent multi-band dynamic processing, newly-developed Class-D amplification with PFC switching mode power supply, and extensive DSP protection technology inherited from Yamaha's top-of-the-line TXn series amplifiers. These four core features add up to class-leading sonic resolution and maximum sound pressure level in remarkably compact, lightweight cabinets. This level of performance makes the DSR series speakers a perfect match for the LS9, resulting in an eminently portable, easy-to-manage live sound system of unrivalled quality. Learn More
6. A ping-pong delay. Ping-pong delay is a type of dual delay where the first echo appears in the 'ping' channel (usually the left), delayed by the ping amount, and the second appears in the opposite 'pong' channel, delayed by the ping time plus the pong time. For example, if you set the ping to 200ms and the pong to 400ms, you'd first hear the ping 200ms after the programme material out of the left channel, and the Pong 600ms after the programme material out of the right channel. This process will then repeat, assuming the feedback values are higher than zero. In audio example 9, Echoboy is set to a ping-pong delay with the Transmitter output style, to give a telephonic effect.
