In addition to these EQ choices, there are two more
selections. First, when flat is illuminated and selected
(by pushing in the speaker control knob), the EQ resets
to flat:
• Low:
±0 dB (unity) @ 100 Hz
• Mid:
±0 dB (unity) @ 1.00 kHz
• High:
±0 dB (unity) @ 10.0 kHz
Like the previous sub-menus, the EQ also has
a left-facing arrow. Illuminating and selecting
this simply returns you to the menu.
Let’s talk about those meters now.
That is what’s called a “Real-Time Analyzer”
[RTA for short]. It measures and displays
the sound of the corresponding output – amplitude
versus frequency components of a continuous
signal – via DSP.
An RTA allow you to see what you hear so you
may easily locate and eliminate feedback and other
anomalies while seeing the EQ changes in real time.
Many audio signals are highly dynamic: music,
speech and even environmental noise contain
significant changes in spectral content as a function
of time. With a digital mixer, musicians and sound
engineers can save time setting up at shows by
recalling previous settings. The DRM’s RTA fits right
in with that, literally displaying frequencies, shortening
the time it takes to tune the main loudspeakers or stage
monitors during setup in a new room.
There are 15 bands on all DRM Series RTAs.
Delay
Probably the easiest parameter to describe
and update. This controls the monitor delay.
In other words, you are going to want to time-align
the speakers throughout the venue so the sound
hits everywhere simultaneously. This is the place.

The delay time ranges from a low of 0.0 ms (ft, m)
to a maximum of 100 ms (112.5 ft, 34.2 m).
In order to change the delay, first push the speaker
control knob when the delay icon is illuminated (see
image above). This opens the delay view.
From here, rotate the speaker control knob clockwise
until the ms parameter is highlighted.
This is the only parameter that can
be changed here; the ft and m delay time
ranges update automatically dependent
on where ms is set.
Push the speaker control knob in to select
the ms parameter followed by rotating the speaker
control knob clockwise (raise the delay time )
and counter-clockwise (lower the delay time).
Like the previous sub-menus, the delay also
has a left-facing arrow. Illuminating and selecting
this simply returns you to the menu.
