The ASD-120 AC Sequenced Power Distro is an extremely compact, low cost rackmount power distribution system that is ideal for touring PA systems, touring musical and theatrical acts, mobile recording facilities, on-location film and video shoots, etc.-any situation where AC power must be distributed to multiple circuits and a hard-wired, built-in system is missing, inadequate, or impractical. Use of a Power Distro is cost-effective, both in terms of the convenience it offers and the elimination of bulky and expensive parallel feeds and related connectors. The ASD-120 offers many more features as well.

The ASD-120 allows you to power up and its six circuits in a sequenced fashion. The sequence is reversed for power down. The delay interval is user-adjustable via an internal trimpot.

Power sequencing is needed whenever various kinds of equipment must be powered up or down in groups, rather than all simultaneously. In audio systems, sequenced powering is often necessary to allow turn-on transients from low level amplifiers and processors to settle down before any power amps are turned on, because simultaneous powering would result in a loud, annoying, and potentially destructive 'pop' reaching the speakers. And in any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that cause circuit breakers to trip even though the steady-state currents are not excessive.
