ESR2600D· Getting Started

Unpacking
Unpack the ESR2600D Amplifier and check for any damage. If you find any damage, notify your supplier immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing 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 ESR2600D Amplifier carton should contain:

• ESR2600D Amplifier control unit
• This user guide
• Two PowerCon detachable power cables

Amplifier rack mounting
The ESR2600D Amplifier is 4 rack units in height and will mount in standard 19″ rack system. Integral rear mounting rack ears are also provided for additional support, do not rely on fixing and mounting the amplifier using just the front panel as support. Use eight screws and washers to mount the amplifier to the equipment rack rails. We recommend using a shock mounted rack for touring use to prolong the life of your amplifier.
Cooling
The ESR2600D Amplifier 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.
IMPORTANT! Please note that for correct full performance of the unit AND ANY WARRANTY COVER, it is important that regular maintenance of the front vents and filters as well as the rear panel fans be inspected and cleaned by removing any dust and debris build-up. Any product failure due to lack of attention in this matter will immediately void any current warranty. (Please refer to notes re ventilation procedures).
ESR2600D · Getting Started
AC Requirements
Two PowerCon cables are provided to connect the ESR2600D Amplifier to suitable AC power supplies. Each cable powers each separate amplifier channel for sufficient current delivery.
THE ESR2600D REQUIRES A GROUND CONNECTION. ALWAYS USE A GROUNDED OUTLET AND PLUG.
The PowerCon is a connector without any circuit breaking capability, i.e. the PowerCon should not be connected or disconnected under load or while it is live. Always isolate your AC supply before disconnecting the PowerCon connector.
The ESR2600D amplifier 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. The Amplifier power plug must be fully removed before any attempt is made to change the operating voltage. The power cord must always be easily accessible for a quick disconnection from the power outlet, if required.
Your amplifier will be supplied preset to the voltage used in your area. The table below provides typical current draw figures for the ESR2600D Amplifier.
The receptacle must be connected to a fuse or circuit breaker. Connection to any other type of receptacle poses a shock hazard and may violate local electrical codes.
Do not allow water or any foreign object to get inside the amplifier. Do not put objects containing liquid on or near the unit.
To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight.
Do not install the unit near heat-emitting appliances, such as a room heater or stove. This amplifier contains potentially hazardous voltages. Do not attempt to disassemble the unit. The unit contains no user serviceable parts, repairs should be performed only by factory trained service personnel.

ESR2600D · Web-server

ESR2600D Web-server
The ESR2600D web-server is accessible using a standard web browser on PC or mobile device. The appropriate ESR2600D network address must be set to access web-server. The web-browser device IP address must be set from the same network range and must be connected into the same network.
IP addresses are assigned to networked devices when they are configured for a specific network. The way that they are assigned can be static or dynamic.
The ESR2600D network address may be set several ways:
Auto IP
(Default) Automatic Private IP Addressing, is a method of automatically assigning IP addresses to networked devices.
A networked device configured to use Auto IP first makes a request to a DHCP server for an address. If the device does not receive an IP address, which happens when there is no DHCP server on the network or when the DHCP server is not responding, the device assigns itself an address. Auto IP addresses always follow this pattern: 169.254.x.y, where x and y are any two numbers between 0 and 255. Unlike DHCP, Auto IP does not require a router or a separate server to assign an IP address. The selected IP address is displayed on display – section NET, or can be obtained using the KV2 diagtool software.
DHCP
Dynamic Host Configuration Protocol. A DHCP server enables network devices to request IP addresses and networking parameters automatically from the DHCP server, reducing the need for a network administrator or a user to manually assign IP addresses to all network devices. The assigned IP address is displayed on display – section NET, or can be obtained using the KV2 diagtool software.
It is important to know that a dynamic IP address can change. If a network device with a dynamic IP address suddenly stops responding at its IP address, it is possible that it has obtained a new lease and its address has changed.
Static
A static IP address must be manually assigned to a network device. This address is typed by the person who sets up devices on the network, and it never changes. A static IP address changes when the person who administers the network specifically changes it.
