Oxmoor 4x4 - Manual (Page 6)

NOTE: The unbalanced output configuration is valid
ONLY if the internal Balanced/Unbalanced output
jumper block has been set to the unbalanced position.
(See BALANCED/UNBALANCED OUTPUT SELECTION,
page 3.)

4x4 CONNECTIONS
PROGRAM OUTPUT CONNECTIONS
(Refer to Figure 4.0)
The 4x4 Buffer Amplifier provides connections for
four program channel outputs.
Each Program Output connection on the 4x4 is made
through a male, XLR-type, 3-pin connector.
PROGRAM OUTPUTS: Pin 1 = Shield, Pin 2 = High,
Pin 3 = Low, electronically balanced outputs accom-
modate balanced or unbalanced lines. Recommended
load impedance is 600 ohms or greater. Maximum
output level is +26 dBu.
PROGRAM INPUT CONNECTIONS
(Refer to Figure 4.0)
The 4x4 Buffer Amplifier provides connections for
four program channel inputs.
Each Program Input connection on the 4x4 is made
through a female, XLR-type, 3-pin connector.
PROGRAM INPUTS: Pin 1 = Shield, Pin 2 = High,
Pin 3 = Low, electronically balanced inputs accept
balanced or unbalanced signals from line-level de-
vices. Nominal input level is +4 dBu with maximum
input level of + 24 dBu.
