Adjust the Left Surround EQ controls on the EQ board to match the figure as
closely as possible. Use caution when adjusting the bass control; many surround
loudspeaker systems are deficient in their low frequency response. Attempts to
boost the output of such systems beyond their capabilities simply wastes amplifier
power and can result in distortion and possibly damage to the surround
loudspeakers.
The equalizer controls interact. Repeat the adjustments until no further adjustment
is required and you have attained the optimum frequency response.
Set the fader to position 0.
