2.Press the SELECT encoder knob to access the editing screen.

3.Choose the backwards arrow by turning the SELECT knob and press it to delete the existing characters of the current preset name.

4.Rotate the SELECT encoder to select new characters from the row above the current amplifier name.

5.Insert selected characters into the new amplifier name by pressing the SELECT encoder knob. Once you select and insert a character, the editing cursor will change direction and advance from left to right.

6.Save the new amplifier name by pressing the DOWN arrow key to activate the SAVE TITLE function.

SETUP 4/4: Contrast

The Contrast screen allows you to adjust the LCD screen’s contrast level. The Contrast parameter ranges from 1–30, with 30 representing maximum contrast. Rotate the SELECT encoder knob to adjust the Contrast setting.

3.2.3 PROCESS screens

Pressing the PROCESS button opens up the various screens that determine the signal path setup and that control processing parameters for the DSP modules: I/O, PEQ, XOVER, DEQ, DELAY, and LIMIT.

You can move between top-level module screens by pressing the PROCESS button.

I/O

The I/O module sets up the signal routing inside the DSP from input to output. Press and rotate the SELECT encoder knob to choose between dual mono, stereo, bi-amped, or bridged routing options.

DUAL

DUAL (dual mono) mode routes each channel input, A and B, through completely separate parallel signal paths with independent outputs for each channel.

Each channel may be processed with its own unique filter, equalization, signal delay, and limiter settings.

STEREO

STEREO mode routes the signal from both the A and B inputs through a single series of DSP modules. The parallel DSP modules process the A and B signals with identical, linked settings (only module “A” parameter settings appear on subsequent DSP module screens).

BIAMP1

BIAMP1 mode splits the Channel A input signal at a programmable frequency point, and then routes the resulting high and low frequency signals through a parallel chain of DSP modules with independent equalization, signal delay, and limiter settings. In BIAMP1 mode, Output A routes low frequencies to a low-range speaker, while Output B connects to a high-frequency transducer.

BIAMP2

BIAMP2 mode operates identically to BIAMP1 mode, except that the output signals are swapped between Outputs A and B (i.e., Output B handles low frequencies while Output A handles high frequencies). The swapped A and B output routing allows the user to quickly correct reversed high/low speaker connections without having to physically access the amplifier’s back panel and manually change the speaker connection.

BRIDGE

BRIDGE mode combines the signals from Inputs A and B into a blended mono signal and then routes the resulting mono signal through a single chain of DSP modules, leading to a combined mono output. The mono output signal is identical at Outputs A and B, and the amplifier responds to a single combined speaker load.

PEQ

The PEQ module deploys up to eight EQ bands for precise sound sculpting. The EQ bands can each be switched between low shelving, high shelving, and parametric modes. For the high shelving and low shelving EQ bands,

the LS12 and HS12 settings provide steeper equalization curves than the LS6 and HS6 settings.

The main PEQ screen displays the composite equalization curve across the frequency spectrum.

Programming equalizers

1.Choose individual equalizers by rotating the SELECT encoder knob. As you rotate the SELECT encoder knob, dotted vertical lines will appear at different points within the frequency spectrum, and the EQ band name will appear in the lower-left corner of the screen (e.g., A#1, A#2, B#1, B#2, and so on).
