Putting Sound in the Picture
AES/EBU (AES3) 24-bit. Also suitable for use with SPDIF (IEC958 type 2) signals
75 Ohm unbalanced (BNC), 0.3V–1.2V Pk-Pk
24-Bit switchable on all AES inputs, SRC Range 30kHz to 100kHz
-117dB @ 1kHz, 0.00014%
AES/EBU (AES3) 24-bit
75 Ohm unbalanced 1V Pk–Pk (nominal) into 75 Ohm load (BNC)
<0.015UI (2.5ns) peak
AES/EBU (AES3) 24-bit.
110 Ohm balanced (XLR or D-Type). 0.2V-7.0V Pk-Pk
24-Bit switchable on all AES inputs, SRC Range 30kHz to 100kHz
-117dB @ 1kHz, 0.00014%
AES/EBU (AES3) 24-bit
110 Ohm balanced (XLR or D-Type)
<0.015UI (2.5ns) peak
24 Bit
Electronically Balanced
2k Ohms at mic level gain settings
10k Ohms at line level gain settings
+18 / -78dB for Mic/Line Inputs
-127dB (150 Ohm source)
-1dBFS @ 1kHz — Better than 0.003%
-20dBFS @ 1kHz — Better than 0.006%
-60dBFS @ 1kHz — Better than 0.3%
20Hz to 20kHz +/- 0.5dB on Mic/Line Inputs
>75dB (Typical 85dB) on Mic/Line inputs
-105dB or better on adjacent channels with 0dBFS tone at 1kHZ on Source
Analogue input for 0dBFS can be pre-set globally to +28, +24, +22, +20, +18 or +15dBU
Pre-fader headroom on mic inputs is adjustable globally from +24dB to +36dB in 2dB steps
For analogue inputs/outputs the system can handle analogue levels of up to +27 dBu from
analogue input to analogue output at line up
These levels must be attenuated in the system before they are fed to digital outputs
