The RDB104 Quad Active Direct Box is a 4-channel impedance matching device designed for the audio professional and musician. Each channel of the RDB104 features 2 paralleled 1/4 in. input jacks, one on the front panel the other on the rear, and one XLR output. An input Level control, a 30 dB output Pad switch, and a Ground Lift switch have also been provided for each channel. Each channels' input impedance is 100k ohms, and the output impedance is 100 ohms balanced. The signal is electronically balanced eliminating low frequency rolloff and unwanted phase shift.
