Design
The AMS DMX 2000 is a 19" 1U rackmount unit. Inside are a processor card, a Deglitch card, and a switch mode supply. It has NVRAM for data retention and a CHB regen pot. The design supports de-glitched pitch shifting. It also needs routine maintenance to keep the NVRAM battery from leaking.
Context
The AMS DMX series was the world's first 15-bit digital delay and pitch shifter. It came out in 1978 and became a studio staple through the 1980s. The series includes the DMX 15-75, DMX 15-80, 15-80S, 15R, and RMX-16.
Market
The AMS DMX 2000 sells for approximately £2,600 (ex. VAT) as of current listings. The unit needs regular power cycling - at least one hour every six months - and the NVRAM battery needs replacing every five years to prevent damage to the processor card.
