Parametric EQ (PEQ) Setup
The Cinema Rhapsody Mach 4 features a multi-
band parametric equalizer (PEQ) that provides
you with tools to dramatically correct acoustical
imperfections. Typically, best results are achieved
using acoustical measurement systems. The
PEQ is a separate PC program to the Cinema
Rhapsody Mach 4 PC program. ADA suggests
running one or the other but not both at the same
time for optimal results. You can also set and
adjust the PEQ from the front of the Cinema
Rhapsody Mach 4.
Each of the seven main channels features a 12-
band equalizer. Each band allows you to set a
center frequency point, Q level and +/- gain level
per speaker channel. You can have all seven main
channels track each other. The subwoofer chan-
nel features an 8-band equalizer with independent
center frequency, Q and level per band.
There are four PEQ presets that store all param-
eters. You can also reset center frequency, Q and
levels individually with the touch of one button.
Lastly, the PEQ can be turned on and off permit-
ting you to A/B your results. Like other Cinema
Rhapsody Mach 4 setup features, you can store
your PEQ settings to a le on your PC.
To set and adjust the PEQ from the front panel of
the Cinema Rhapsody Mach 4, while in the Setup
Mode navigate the cursor to PEQ using the Mode
knob and press the knob.
Pressing the Mode knob toggles its behavior
between selecting bands to adjust or selecting
channels to adjust.
While on the desired frequency band, turning the
Input knob raises or lowers the Gain with the letter
G showing you the numeric level.
While on a band, pressing the Input knob toggles
the control to Frequency Center Point and Q set-
tings. Here turning the Mode knob advances the
frequency through 10000th’s, 1000th’s, 100th’s,
10s’, and 1’s. Turning the Input knob adjusts
that numerics value. Turning the Mode knob to
Q permits the Input knob to adjust the Q setting.
Press the Input knob to exit this feature.
While on a Preset number (R = Recall, S = Store),
press the Mode knob to recall or store.
