MEQ-2000 24/96 Multimode Equalizer
SETUP MENU – Reference Generator (GEN)
The Reference Generator ( GEN ) is a precision tool providing high-quality audio test
signals. The THD+N of the generated sine wave is better than –144dB. For acoustical
measurements, uncorrelated white and pink noise generators are available. The signal
frequency’s range extends to subsonic and ultrasonic ranges, from 10Hz to 43.5kHz. For
hardware and digital signal path testing, special features include digital constant
( CONST ) and up/down counting function ( TRIAN ). Use caution with these functions, as
they can damage your loudspeakers if used incorrectly.
There are five active buttons in GEN mode:
F1 – ON Switches the GEN on or off.
F2 Toggles between CH1 and CH2 setup (if CH LINK in MODE menu is Off).
F4 increases the adjustment resolution from 1/12 octave ( COARSE ) to 1Hz
( FINE ).
F5 – MODE Switches to MODE menu for advanced options.
F6 – EXIT Switches to main SETUP menu.
Parameter Window
The
cursor keys can be used to highlight the selected parameter, and the
parameter wheel can be used to change its value. The cursor keys provide for fast
frequency adjustment in 1/12 octave increments.
For the signals CONST and TRIAN the enlarged symbols appear in the middle of the
display to warn against these non-audio signals.
The following parameters can be viewed and/or adjusted:
TYPE selects the type of generated test signal: SIN (sine wave), FREQ SW (sine
wave with frequency sweep), PINK (pink noise), WHITE (white noise),
CONST (digital constant) or TRIAN (digital up/down counter).
