Page 8 - Clip limiter; NON APPLICABLE; Limitador de picos; Clip Limiter

8 Clip limiter WHAT IT IS When the audio signal drives the amp's output circuit beyond its power capability, it clips, flattening the peaks of the waveform. The clip limiter detects this and quickly reduces the gain to minimize the amount of overdrive. To preserve as much of the program dynamics as ...

Page 9 - Input filter; Filtro de entrada; Eingangsfilter

9 Input filter WHAT IT IS The low-frequency (LF) filter rolls off signals below either 30 Hz or 50 Hz. This improves bass performance by limiting sub-audio cone motion, making more power available for the speakers' rated frequency range. The filter settings for each channel are controlled individual...

Page 10 - Parallel input mode; Modo de entradas paralelas

10 Parallel input mode WHAT IT IS The "Parallel Input" switches let you operate the amplifier in parallel mode, delivering the same signal to both channels without using a Y-cable. Each channel drives its own speaker load, with independent gain, filtering, and clip limiting. Set switch posit...

11 FEATURES & SETUP Bridge mono mode WHAT IT IS Bridged mono mode combines the power of both amp channels into one speaker, resulting in twice the voltage swing, four times the peak power, and approximately three times the sustained power of a single channel. This mode uses Channel 1's input, ga...
