AudioFire 4’s front panel has two universal inputs (1 – 2) with meters and trim knobs, a phantom power indicator (+48v), and a power button with an amber power indicator light. There is also an 1/8” stereo headphone output jack, with a corresponding volume knob, which monitors analog outputs 1 and 2.
AudioFire 4 has two analog line inputs (3 – 4) and four analog line outputs on the rear panel. These analog inputs (3 – 4) operate with an input impedance of 10Kohms. The input and output connections can be used with balanced or unbalanced cables via the ¼” connectors. By default, the inputs and outputs are set to receive or send a +4dBu signal.
