CONTOUR
--
Our unique CONTOUR circuit offers continuously variable control of 2 vastly different response curves. In
either CURVE position when the SHAPE control is all the way off (CCW) the response curves are completely FLAT.
Curve A
(Blue)
Provides a variable pre-shaped curve that boosts lows and highs while simultaneously cutting Mids. The slopes are fairly
gentle which keep the tone shaping very musical. This curve covers a wide range of sounds from flat to classic to modern
depending on the position of the SHAPE control.
Curve B
(Amber)
Provides a variable pre-shaped curve with attenuated high mids and highs, a low mid bump, and a slight roll-off of the
lowest bass frequencies. Again, the slopes are fairly gentle which keep the tone shaping very musical. This curve is
intended to provide sounds in the range of vintage amps and vintage cabinets that do not have tweeters.
ACTIVE EQUALIZATION
– The
MAGELLAN
™
800
contains an active 3 band equalizer with a sweepable parametric
mid-range frequency control. The mid-range filter is typically (but not always) used to reduce or remove offending
frequencies in the instrument, speaker cabinet, or room response; or to boost response to achieve a particular voicing.
Spend some time experimenting so that the process becomes creative as well as corrective.
Bass
+/- 15dB boost/cut shelving curve with a corner frequency of 75Hz
Mid
+/- 15dB boost/cut of the variable mid frequency selected
Freq.
Variable mid frequency from 150Hz-3kHz
Treble
+/- 15dB boost/cut shelving curve with a corner frequency of 6kHz
MASTER VOLUME
– This control adjusts the overall volume of the amplifier and also adjusts the input level of the EFX
LOOP RECEIVE and AUX IN jacks. Typically, best results are obtained when this control is operated between the 9:00
and 3:00 positions.
MASTER SECTION STATUS LED
--
BLUE
-- Indicates that the low voltage power supplies are active and that the amplifier is ON and ready to operate.
RED
-- Indicates that the amp is in either “standby” or “protect” mode. The RED light will illuminate during power turn-on
and turn-off to indicate “standby” mode. This is normal. It will also illuminate temporarily to indicate “protect” mode during
any fault condition such as overheating or a short on the speaker outputs. If the MASTER LED does not eventually switch
to BLUE but remains RED continuously, turn the amp off and consult a repair technician.
