The RMC-1 Menu System
Filter Frequency
For each filter, you can set the center frequency of the band to any frequency between 20 Hz and
20 kHz, and the result will be displayed in Hz (or kHz).
Test Tone Level
The Test Tone Generator on the RMC-1 offers both pink noise and sine wave test tones at various
frequencies for use in calibrating the parametric EQs. For each type of test tone you may select
three different output levels: High -85 dB, Medium - 75 dB, Low - 65 dB, and Off for use with
external calibration signal sources.
Note: The actual sound pressure level your system will produce at each different output
level setting will depend on many factors, including the gain of your amplifiers and the
efficiency of your speakers. The "dBspl" settings shown for each level choice are therefore only
approximations of the sound level that may be produced - based on the characteristics of a
"typical system". Always use common sense and select reasonable sound pressure levels at
which to perform tests based on the results of your measurements.
There is only a single Tone Generator, even though the control appears in duplicate under the
options for each filter.
If you select Off (External) as your test signal source, then whatever input source is currently
selected on the RMC-1 will be used as the test tone source. This input will be treated as if it were
playing in the equivalent of All Stereo Mode, but the resulting output signal will then be sent to
ONLY the currently selected channel.
Test Tone Frequency
If you have selected sine wave test tones using Test Tone Level, then you can use the Test Tone
Frequency control to set the output frequency of the sine wave test tone. There is only a single
Tone Generator, even though the control appears in duplicate under the options for each filter.
The Test Tone Generator output frequency can be set to any frequency between 20 Hz and 20 kHz,
and the result will be displayed in Hz (or kHz).
Note: You may notice that the test tones are not absolutely pure continuous sine waves - and
may include audible ticking noises at certain frequencies. While audible, these noises are
simply artifacts of the program code used to generate the test tones; they do NOT significantly
affect the energy distribution of the test tones, and have no significant effect on measurements
performed using the test tones.
