1) BAT Battery Indicator: When a guitar cable is connected to the
output jack, the BAT LED will light, and the System 600T MK II
preamp/Eq functions are activated. (Please note that the digital tuner
function can be activated without connecting
a cable to the output jack). To prevent
excessive battery consumption, unplug your
cable from the output jack when the System
600T MK II is not in use. When the battery
is wearing out, the LED will become dim,
and the signal will become distorted. If the
LED does not light, remove the chassis and
replace the battery.
2) PIEZO: This control adjusts the level
of the under-saddle bridge piezo pickup.
3) AUX: This control adjusts the level of
the auxiliary input, either an Alvarez ASP50
MK II sound hole pickup or an Alvarez
ACM50 condenser microphone.
4) LEVEL: This switch adjusts the
input level of the AUX input. When using
a magnetic sound hole pickup or condenser
mic, this switch should be set in the -20dB
position. When a dynamic microphone
is used, this switch should be set in the
0dB position.
5) PHASE: This switch reverses the
polarity of the PIEZO input relative to the
AUX input. If the polarities of the different
inputs are “out of phase”, a noticeable loss of
low frequencies (bass) will occur. If there is
a loss of fullness, or low end when two input
signals are mixed, reverse the position of this
switch (In/Out) to correct the polarity.
Note: If only one input is used, this switch will have no effect.
6) TREBLE: This slider provides +/- 15 dB of boost/cut at 10kHz.
In its center position, there will be no effect.
7) BASS: This slider provides +/- 15dB of boost/cut
at 100Hz. In its center position, there will be no effect.
8) MID: This slider works in conjunction with the MID
FREQ control. It provides +/- 15 dB of boost/cut at the
center frequency determined by the MID FREQ control.
9) MID FREQ: This control adjusts the center
frequency of the MID slider, variable from 600Hz to
1.2kHz. If the MID slider is set to its center position, no
effect will be heard. Maximum effect of this control can
be heard as the MID slider is set for boost or cut.
Note: The main Eq system (TREBLE/MID/MID FREQ/
BASS) controls will only affect the piezo input signal.
These controls have no effect on the AUX input signal.
10) MASTER: This control is the Master Volume,
which adjusts the overall output of the System 600T MK
II, including both the PIEZO and AUX inputs.
11) NOTCH: This switch engages a notch filter,
which is used to control feedback in live performance
applications. When the switch is in its IN (down) position
a deep, narrow band of frequencies is cut from the signal,
depending on the position of the FREQ control. This
notch filter is located “post Eq” in the circuit and will
affect the combined PIEZO and AUX input signals.
12) FREQ: This control adjusts the center frequency
of the “anti-feedback notch”. With the NOTCH switch
engaged, turn the MASTER control up until feedback is
heard. Adjust the FREQ control until the feedback
disappears.
The Alvarez System 600T MK II has been designed to accurately reproduce
the natural sound of an acoustic guitar when used with a wide variety of
sound reinforcement and recording equipment. Sound is very subjective.
We urge you to experiment with the many control capabilities of the
System 600T MK II in order to “dial in” the sound that is right for you.
