The Fredenstein U1631 is an analog level meter with 16 channels. It is perfectly suited for monitoring the RMS values directly before the converter to avoid digital distortions there. It features a high resolution of 31 LEDs and 60dB per channel. The reference level for 0dB is +4dBm. The signals are fed in at the rear via the 2 pairs Tascam D-sub and tapped off again.
