® independent Left and Right Channei Level Adjustment for Twelve Frequency Bands
The EQ-540 has twelve (left/right) pairs of level controls with center frequencies ranging from 16Hz to 32kHz. The very low and very
high (16Hz and 32kHz) frequency controls double as sub- and ultrasonic filters. Each level contro! has its own LED indicator, enabling
the user to check the current response setting even from a distance. The slider-type controls, situated side by side for the left and right
channels, enhance control accuracy and make it easy to maintain balance between channels.
@ Built-In Test Frequency Generator for Accurate Level Setting
The EQ-540 can generate both warble and fixed tone test signals in two different modes: "spot" and "stepped" sweep. Using warble
test tones minimizes the influence of standing waves and natural room resonances, so much more accurate level settings are possible
than with conventional fixed frequencies. In spot mode, the test frequency rises in single steps each time you press a key. In the stepped
sweep mode, the unit generates test signals consecutively at each center frequency from 32Hz to 16kHz. In both modes the corresponding
LED indicators light and the fluorescent display provides a digital readout of the frequency being tested. Test signals may be generated
simultaneously in both channels or in each channel separately.
