Linear Crosstalk: > -80 dB, main to sub or sub to main channel
(referenced to 100% modulation).
Non-linear Crosstalk: > -80 dB, main to sub or sub to main channel
(referenced to 100% modulation).
38 kHz Suppression: > 70 dB (referenced to 100% modulation).
76 kHz Suppression: > 80 dB (referenced to 100% modulation).
Pilot Protection: >
-
65 dB relative to 9% pilot injection, ± 1 kHz.
57 kHz (RDS/RBDS) Protection: better than
-50 dB.
Connectors:
Two EMI suppressed female BNC, floating over chassis ground.
Maximum Load Capacitance: 5nF (at 10 ohms source impedance).
Maximum cable length: 100 feet/30 meters RG-58A/U.
Analog Audio Input:
Left/Right Stereo.
Electronically balanced.
Input impedance 10k ohms resistive.
Maximum Input Level: +22 dBu.
Nominal Input Level: +4dBu, which nets a -
18dBFS input meter reading
on a steady-state signal when the Input Gain control is set to 0.0dB.
Program material with a nominal average level (VU reading) of +4dBu
will typically produce peak readings on the input meter in the range of -12
dBFS to
-
6dBFS. This is the correct operating level.
A/D Conversion:
Crystal Semiconductor CS5361, 24 bit 128x over-sampled delta sigma
converter with linear-phase anti-
aliasing filter. Pre
-
ADC anti
-alias filter,
with high-
pass filter at <10 Hz.
Connectors:
Two, EMI-
suppressed XLR
-
female. Pin 1 chassis ground, Pin 2 "Hot".
Analog Audio Output:
Left/Right Stereo. Electronically balanced.
Output Impedance 20 ohms.
Minimum load Impedance: 600 ohms.
Output Level adjustable from -2 dBu to +22dBu peak in 0.1dB steps.
D/A Conversion:
Crystal Semiconductor CS4391, 24 bit, 128x oversampled.
Connectors:
Two, EMI-
suppressed XLR

male. Pin 1 chassis ground, Pin 2 “Hot".
Digital Audio Input:
Configuration: Stereo per AES/EBU standard, CS8420 Digital Audio
Transceiver with 24 bit resolution, software selection of stereo, mono
from left, mono from right or mono from sum. Automatically accepts
and locks to input sample rates between 32 and 108 kHz.
