2 input pairs can be switched to XLR balanced connectors

Independent balanced/unbalanced select for the L & R channel

Each channel's input is switched by its own gold-on-silver contact relay

4 output jack pairs with specialized functions:

1 Main output jack pair is balanced XLR, polarity is switched by remote

1 Main output jack pair is unbalanced RCA, polarity is switched by remote

1 output jack pair is unbalanced RCA, inverted polarity only

1 output pair is unbalanced RCA, normal polarity, fixed level for recorders

Dual-mono left & right channel circuit boards minimize crosstalk
