Overview

The Middle Atlantic USC6R Universal Sequencer Controller is designed for audio/video professionals who need controlled, staged power-up sequences for rack-mounted equipment. Rather than switching everything on at once — which can cause inrush current spikes and potential equipment damage — the USC6R distributes power across six sequential steps with selectable delay intervals of 1, 3, or 6 seconds between each step. This staged approach protects sensitive AV gear such as amplifiers, processors, and displays by ensuring each component powers up in the correct order.

Triggered via contact closure, the USC6R integrates easily with automation and control systems commonly found in commercial AV installations. It serves as a dedicated sequencing controller, working alongside your existing AC power distribution units to manage the timing of power delivery. For installers working with Middle Atlantic racks and power strips, the USC6R slots neatly into the ecosystem, adding an essential layer of protection and automation to any professional AV setup.

Key Features

6-step sequencing control to any AC power distribution system that can be controlled via contact closure

Pros & Cons

👍 Pros

  • Six-step sequencing provides granular control over complex AV power-up routines.
  • Selectable 1, 3, or 6-second delay intervals let you match timing to your equipment's requirements.
  • Contact closure control offers simple, reliable triggering compatible with most automation systems.
  • Compact controller designed to integrate into existing Middle Atlantic rack setups.

👎 Cons

  • Only three preset delay intervals — no custom or continuously adjustable timing.
  • Contact closure control only; no network or RS-232 triggering built in.
  • Does not include power distribution — requires a separate PDU for actual AC outlets.
  • Limited to six steps, which may not be enough for very large installations.
