The revised AD-9 improves on one of Maxon's most coveted models in order to create the best sounding, most reliable analog delay ever. Improved construction including through-hole, glass reinforced epoxy PCB's, snap-in PCB connectors, and true bypass switching guarantee trouble free performance. The combination of one Panasonic MN3205 BBD IC and one Signetics NE570 compander provides warm yet crystal-clear delay time with adjustable repeats and zero clock noise.

The AD-9 captures all the classic sounds of the most sought-after vintage analog delay units. With 10-300 milliseconds of variable Delay Time provided by a Panasonic MN3205 (low voltage BBD IC, now out of production), the AD-9 can produce a wide variety of time-delay effects, from Rock-A-Billy slapback echo to erratic, runaway delays. The unit's Repeat control provides additional spatial effects by adjusting the repeats from one to infinity to emulate various room sizes. Calibrated for self-oscillation, the AD-9 is capable of "UFO landing" effects as well as many other bizarre sounds limited only by the user's imagination.

The AD-9's Delay Level control adjusts the mix between dry and effected signals, allowing the delayed signal to sit back behind the input signal to add subtle ambience or right up in front for greater impact. Stereo outputs provide a variety of signal routing options for use with multiple amplifier setups or mixer channels. All sounds are provided with zero clock noise thanks to one Signetics NE570 compander and true bypass switching using a 4PDT mechanical switch.
