Effect Parameters
■ CONTOUR
Using the 0 value as a reference (flat setting), negative values cause an
increasing boost in the low range and positive values cause an increasing
boost in the high range. When the EQ module is On, this parameter is always
active. Check this parameter if the 4-band EQ effect type setting does not
seem to produce the desired results.

■ ZNR
ZNR (ZOOM Noise Reduction) serves for reducing noise during play pauses
or silent passages. Higher setting values result in more efficient noise
reduction. Set the value as high as possible without causing the sound to be
cut off unnaturally.
■ COMBO
Simulates a combo type amplifier. When this setting is selected, the amp
simulator is on and ZNR is off.
