INPUT CONNECTIONS:
6. LINE IN (SEE FIGURE 2):
Connect line level audio source (i.e. MIC/LINE mixer) to the LINE IN phono jack. For balanced line level
source, connect to 600 OHM terminal
block. Note: The 600 OHM from the terminal block is disconnected when a phone plug is inserted in the LINE IN phono jack.
7. BOOSTER OUT (SEE FIGURE 2):
The BOOSTER OUT signal allows for cascading amplifiers. The BOOSTER OUT is the LINE IN signal buffered and available at the BOOSTER
OUT phono jack.
