Operating Manual - 24.24M Matrix Processor

9.2 Output Audio Functions

The following functions are available on all outputs: Mixer, High Pass/Low Pass Filter, Delay, EQ, Gain, Limiter,

and Mute.

9.2a Output Matrix Mixer

Output channels can have any or all inputs

as sources, and the output matrix mixer allows the

level of each connected input to be adjusted in the

“matrix mix” to each output. Note that for a given

output, unlinked inputs are disabled in the mixer.

Adjustment range is from +12dB to off. To set a

level control to unity (0) within the matrix mixer,

select an input level control by clicking on it and

pressing <ctrl> + <z>, or by pressing <ctrl> +

<click> on the level adjustment control. Individual

input channels in the matrix mixer can be muted

independently from the main input or output mute

blocks.

9.2b Hpf/Lpf - Crossover

Bandpass or crossover functions on the Pro-

tea 24.24M are available only on the output chan-

nels. Every channel's crossover consists of a high

pass filter (HPF) and a low pass filter (LPF), along

with the frequencies and filter types used. Each

output's crossover section is essentially a bandpass

filter, making it necessary for the user to map out

ahead of time which outputs will be used for the

various frequency bands, and set the overlapping

filter frequencies and types accordingly. Note:

The High Pass Filter determines the lower frequency limit of the signal, while the Low Pass Filter determines the upper

frequency limit. Be careful not to accidentally send low frequency signals to high frequency drivers. Check the loud-

speaker specifications to determine a safe operating frequency range.

The frequency

range for the high pass

filter (HPF) is 20Hz to

20kHz, with an option to

turn the filter off at the

low end of the frequency

selection. The low pass

filter (LPF) offers the

same frequency range,

with the "off" option at

the high end of the fre-

quency selection.

There are eleven

types of filters available

in the crossover section,

each suited to a specific

preference or purpose.

The slope of each filter

type is defined by the
