This manual assumes the full Stage 5 System and provides the information for initial settings accordingly.
STEP 1 – ADJUST TWO-CHANNEL AMPLIFIER
Looking at the NA2-400.2 shown in Figure 15.1, make the following initial adjustments:
● X-OVER - Switch to “HP” position.
● LEVEL - Rotate control to halfway (pointing
up). This represents an input level that will
closely match the source unit’s output at full
volume allowing the amplier to achieve full
power without notable distortion.
● HP - Rotate control to halfway (pointing up).
This is approximately 80HZ.
● LP - Not used in this application.
STEP 2 – ADJUST MONO AMPLIFIER
Looking at the NA2-400.1 shown in Figure
15.2, make the following initial adjustments:
● BOOST - Switch to “0dB” position.
● LEVEL - Rotate control to halfway (pointing
up). This represents an input level that will
closely match the source unit’s output at full
volume allowing the amplier to achieve full
power without notable distortion.
● LPF - Rotate control to halfway (pointing
up). This is approximately 100HZ.
● SUBSONIC - Leave in the lowest (15Hz position). If the subwoofer has trouble with the lowest notes in
your choice of music upon testing, you can adjust up slightly about 1/4 turn.
