6 Installation
* Note: Please take into consideration ventilation of your equipment. A well-ventilated equipment
rack will ensure optimum operation and longevity of your equipment. It’s often a good idea to leave
1 free rack-bay position between your equipment to allow ventilation As to avoid overheating,
please do not place the EP84 on high temperature devices such as power amplifiers.
3.3 Mains Voltage & front panel power switch
Mains Voltage
Important - Before you connect your EP84 to the mains power supply, please
make sure that your local voltage matches the voltage required by the unit!
The EP84 has a professional internal power supply suitable for operation between
AC 110/115v — AC 220/230/240v. A voltage configuration switch on the left hand
side of the rear panel should be set to match the appropriate voltage of your mains
power supply. Simply slide the selector switch with your finger or a small flat-blade
screwdriver to either the 110v or 220v position to configure the unit accordingly.
To connect the EP84 to your mains power source simply connect the included standard IEC mains
power cable to the EP84’s three (3) pin power connector socket.
Power on/off switch & LED power indicator
The EP84’s power switch can be found on the right hand side of the front panel.
To enable power to the EP84 or ‘turn on” simply place the power on/off switch
into the down position. The LED power indicator will illuminate to indicate the
EP84’s operational state as ‘on’ and ready for operation.
To power down or ‘turn off’ the EP84, simply place the power on/off switch
into the up position. The LED power indicator will not illuminate to indicate the
EP84’s operational state as ‘off’.
* It’s always good practice to protect your ears, and other audio equipment by taking appropriate
care when powering up any audio equipment. Being aware of your gain structure, and performing
a structured power up sequence with your equipment will help to avoid unexpected audio signals
bursts. It’s a good idea to power up devices in sequence from the start of the signal chain to the
end of the signal chain (EP84 -> recording device -> power amplifier/active monitors).
