Horn EQ
The Horn EQ provides a 6dB per octave high frequency boost
that is sometimes required for high frequency horns. The
frequency control sets the low frequency corner of the filter.
To return to the Main Menu, select Discard and Exit or Save
and Exit.
Delay
Delay can be used to align drivers within a loudspeaker or to
delay auxiliary speakers like those installed under a balcony. A
short delay can also be used to delay the main speakers to align
them with the drums or bass guitar. A total of 125 mS of delay
is available on each channel. 5 mS of delay is available in 41.67
uS steps for driver alignment. 120 mS is available in 1 mS steps
for system alignment. These delays can be set independently
so that the driver alignment offset can be maintained when the
system alignment delay is adjusted.
The first screen in the delay Sub Menu allows the user to
decide whether the delays will be set independently or B=A.
This selection only applies to the 1 mS step system delay,
leaving the driver alignment delays to be set independently.
The IPR2
amplifiers display the equivalent delay distance in
™
meters and feet in the system delay and centimeters or inches
in the driver delay.
Limiter
The IPR2 DSP has limiters available on each channel. These
limit the signal level to the input of the power amplifier stage.
The limit threshold starts at zero and is adjusted in -1 dB
steps, reducing the maximum output. You must be aware that
the IPR2 DSP works the same as most other amplifiers in that
their maximum output depends on the line voltage and load
impedance. Depending on load, you may need to reduce the
limiter up to 3 dB before the output is reduced.
Memory
The IPR2 has four memory locations where its settings can be stored and then recalled. Each location has a six-character name to
identify the file. The name of the active preset is also displayed in the Main Menu "Memory" screen.
