3.4 Audio Connections EP84 rear panel Analog Inputs 8 x combo (XLR & TS) input connectors can be found on the front panel. These are the direct analog inputs to the EP84’s 8 individual preamplifier modules. Input your audio source material via either XLR or 1/4” TS cable connectors. Analog outputs Both balanced +4dB XLR and unbalanced -10dB 1/4” TS analog output connectors are provided for each of the eight (8) preamplifier channels.
* Phantom power is a voltage distribution system utilizing standard microphone cable. It is useful (and often required) for powering condenser microphones connected to your audio system. If any of your microphones require phantom power, simply enable the corresponding channels phantom power switch to activate a constant 48v power supply. 4.
Make the necessary connections - Connect your desired source signals to the EP84 via the front panel COMBO connectors (either XLR or 1/4” jack connector). - If you would like to insert an external processor (ie. Compressor, EQ, etc) in the channels audio signal path, connect the outboard device using a standard 1/4” TRS insert cable. - Make the necessary connections from the corresponding channel outputs on the rear of the EP84 to your desired destination inputs (Mixer, recorder, etc).
* Note: Both analog outputs from the EP84 and the PR8IIA’s ADAT digital output function simultaneously. Enhance the front end of any ADAT compatible multi-track digital recording system with the PR8IIA. Ask your dealer for more information. 6.
