FEATURES

The ASD-120 allows you to power up its six circuits in a sequenced fashion. The sequence is reversed for power

down. The overall delay interval is user-adjustable internally. For system components that present a large inductive

load to the AC line (such as power ampliers), sequenced power can avoid excessive inrush currents that can

cause circuit breakers to falsely trip. Sequenced power is needed whenever various kinds of equipment must be

powered up or down at different times. Also, sequenced power is often necessary to allow turn-on transients from

low level preampliers and processors to settle down before any power amps or powered speakers are turned on.

This is because simultaneous powering can result in a loud, annoying, and potentially destructive “pop” reaching

the speakers.

The user has complete control of each of the ASD-120’s outputs. A three position front panel switch for each

control output allows it to be included in the sequence, or to be overridden. Indicator LEDs show when each

output is “on.” While the ASD-120 is ideal for controlling MINIPORTs, it can also control Furman’s PL-PRO

HT, or any other devices that need to be switched when a particular time delay has elapsed. An ASD-120 can

also control additional ASD-120’s, providing complete power sequencing control for even the largest systems.

The ASD-120 can handle up to 120 amps of incoming power, distributing it to six 20 amp, 120V circuits. Each

circuit has a front panel status indicator that lights up when it is turned on, and a 20 amp duplex outlet on the

rear panel.

The ASD-120’s design incorporates four voltage input busses, allowing wiring for 120V/240V single phase, or

208V three phase voltages. A strain relief clamp is provided that can accommodate a cable or wire bundle up to

1.5 inches in diameter. Cable termination is a simple process of breaking out and stripping the individual conduc-

tors and connecting them with set screws, and then tightening the strain relief clamp. Complete instructions ac-

companying the unit detail the process of selecting and terminating the supply cable. The ASD-120 provides basic

spike and surge suppression, with metal oxide varistors (MOV’s) connected between the hot and neutral conduc-

tors of each circuit. The MOV’s respond to line-coupled spikes in less than a nanosecond, clamping transient

voltages to safe levels of 200V peak or less.

Furman products are protected by a limited three year warranty, covering defects in materials and workmanship provided that the registration card is lled out and returned by the customer.

Otherwise, a one year warranty applies. Products must have proof of purchase from a Furman authorized dealer.
