Rane RPM 26i User Manual

In addition to the individual signal processing blocks
described above, the RPM 26i contains
Input Blocks and
Output Blocks, shown above. These terms simply describe a
subset of the available processing blocks and allow conve-
nient copying of settings from multiple processing blocks.
For example, once you’ve properly set up one-half of a stereo
3-way speaker stack, right mouse click on any output process-
ing block that you’ve already tweaked. A menu appears that
permits clipboard copying of all of the
Output Blocks’
settings (
Copy Output Settings). This includes the settings
for the Fine Delay, PEQ, Trim and Limiter. Then right click
on the corresponding
Output Block for the other speaker
stack. The pop up menu appears again allowing you to paste
(
Paste Output Settings) all the settings from the previously
tweaked Delay, PEQ, Trim and Limiter. Then do the same for
the other two loudspeaker drivers and you have a great
starting point to properly adjust the other speaker stack. The
Input Block provides this same Cut and Paste functionality.
OUTPUT BLOCKS
INPUT BLOCKS &
GENERATOR (PINK NOISE OR SINE)
Pink Noise or Sine wave signals are
available in some DSP Programs. A ‘
G’
appears in the simple graphic in the
Choose
DSP Program window, indicating that a
given DSP Program supports these Generator
test signals. The
Pink Noise is provided as a
test signal for listening to comb filtering in speaker arrays or
for listening for room reflections. The
Sine wave provides a
convenient test signal, helpful in setting gain structures or for
more accurately hearing specific-frequency room reflections.
The signal Generators default to a
Muted state when new
DSP Programs containing Generators are requested. Click
Mute to unmute the Generator. Click the up or down arrows
to adjust the Generator’s
Level in ½ dB steps. The maximum
attenuation is 40 dB. The Generator levels are calibrated in
dBFS, i.e. at 0dB the Generator is sending a full scale digital
signal to the D/As.
Double-click on the Generator block to open the detail
window. A vertical scroll bar adjusts the Level in three ways.
Click and drag the Thumb directly, click between the Thumb
and the arrows for 5 dB steps or click on the up or down
arrows for ½ dB steps.
Radio buttons on the left allow selection of
Pink Noise or
Sine Wave as the Generator source. If Sine Wave is selected,
the edit box to the right dictates the
Sine Wave frequency in
Hertz. One Hertz steps are accepted.
DSP Programs with two Generators contain two
uncorrelated pink noise sources, required when you wish to
listen to “stereo” pink noise signals. Also, the two sine wave
generators are not guaranteed to be in phase. Be sure to
always
Mute the RPM 26i Generators any time you use an
analyzer for system measurements, since the analyzer must
use its own internal generator for such measurements.
MUTE ALL
The
Mute All button is provided for
those moments when you quickly need
to turn all of the RPM 26i Outputs off.
Please note that once all outputs are muted, clicking
Mute All
again does not unmute all of the outputs. All outputs are also
muted each time you choose a new DSP Program from the
Device menu’s Choose DSP Program option. This pur-
posely forces the user to unmute each output separately and
allows one to reflect on the consequences of unmuting each
output independently.
