Hear Technologies Hear Back PRO 4-Pack Personal Mixing System (Analog Input)

This 4-pack includes one Hear Back PRO Hub and four Hear Back PRO Mixers. The system features a 1/8" (3.5 mm) TRS stereo mini-jack input, an XLR 3-pin microphone input, and an RJ45 connection. It offers two 1/4" TRS balanced line outputs, a 1/4" TRS unbalanced stereo headphone jack, and a 1/8" (3.5 mm) unbalanced stereo headphone mini-jack. The unit supports 15 V for XLR input, 24-bit Delta-Sigma A/D and D/A conversion, with a maximum input level of +18 dBu for aux and -30 dBu for mic. The maximum output level is +24 dBu, dynamic range of 117 dB typical, noise of -93 dBu at 192 kHz sample rate (A-weighted), impedance of 10 kOhms for aux input and 1 kOhm with 150 Hz high-pass filter for mic input, frequency response of 20 Hz to 20 kHz (±0.15 dB) for line outputs, THD + N of 0.004% typical (at 1 kHz, +15 dBu) and 0.008% typical (at 20 Hz to 20 kHz, +4 dBu), and IMD of 0.02% typical (at +4 dBu, 60 Hz/7 kHz) for line outputs and
