ESP4000 · Getting Started
Unpacking
Unpack the ESP4000 and check to see if there is any damage to it. If you find any damage notify your supplier immediately.
Only the consignee may institute a claim with the carrier for any damage incured during shipping. Be sure to save the carton
and all packaging materials for the carrier's inspection.
Should you ever need to ship the unit, only use the original factory packaging. If the shipping carton is unavailable, contact
your supplier to obtain a replacement.
The ESP4000 carton should contain:
• ESP4000 power amplifier
• User's Guide
• 2x PowerCon detachable power cable
Rack Mounting
ESP4000's will mount in standard 19" rack systems. Integral rear mounting rack ears are also provided for additional
support. It is important that you do not rely on fixing and mounting the ESP4000 using just the front panel as support. Use
eight screws and washers to mount the amplifier to the equipment rack rails (four for the fronts and four for the rear). We
recommend using a shock mounted rack for touring use to prolong the life of your ESP4000.
AC Power Requirements
The ESP4000 is an advanced power amplifier. Understanding power distribution, voltage and current requirements, as well as
electrical safety issues, is critical to the safe operation of the ESP4000.
Cooling
The ESP4000 has a comprehensive cooling system featuring chassis-sealed PCB board mounting and shock mounted, speed
controlled fans. This means that the cooling system never drives air across PCB boards, connectors or components ensuring
prolonged electronic component lifespan and minimizing maintenance cycles.
Air is drawn into the front of the amplifier by the two fans on the rear panel, this passes over the cooling fins of the heat sinks
and exhausts through the rear. If the heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the
load.
It is important to have an adequate air supply at the front of the amplifier, and enough space around the rear of the amplifier
to allow the cooling air to escape. If the unit is rack-mounted, do not use doors or covers on the rear of the rack; the exhaust
air must flow without restriction. If you are using racks with closed backs, use fans on the rear rack panel to ensure an ample
air supply.
AC Power
The ESP4000 uses a pair of PowerCon 3-pole AC main systems with locking connectors to prevent accidental disconnection.
The main AC connectors (blue) serve as the power inputs.
The ESP4000 operates in either 115V, 230V or 250V modes. Although pre-configured at the factory, the unit's operating
voltage mode can be changed in the field.
