6. BALANCED OUTPUTS
Output impedance is 125Ω, each side, balanced, and levels up
to +18dBu maximum full scale. 1/4" phone connectors and
XLRs provided. Both S/PDIF and AES outputs are active at all
times.
7. BALANCED INPUTS
Combined 3 pole XLR and 1/4" jacks, electronically balanced.
Input impedance is 50kΩ unbalanced, and 100kΩ balanced.
Inputs accept input levels from -22dBu to +20dBu.
8. INPUT LEVEL
Two-position (In/Out) switch for matching input gain to the
source being used. In position adds 20dB of input gain
(unbalanced) to the input stages. Out position provides 0dB of
gain (balanced).
