Crest Audio Pro-LITE® Series Power Ampliﬁ ers

The dual channel power ampliﬁ ers shall be ultra-high efﬁ cient, high-power, lightweight Class D designs. The power ampliﬁ ers shall be available in four power levels with and without onboard Digital Signal Processing for each channel. Each channel shall be low impedance output with power levels of 900, 1,500, 2,600 and 4,800 watts per channel at 2-ohms (at 1% THD both channels driven at 1kHZ). Channels shall be bridgeable on the two lower wattage models. Bridged power shall be 1,950 and 3,000 watts at 4-ohms (at 1% THD both channels driven at 1 kHz).

Input signals shall be connected via two combination XLR and ¼” phono jacks. Inputs shall be selectable as parallel, stereo or bridged inputs. Input functions shall be selectable as full-range, sub or through inputs. On the two higher powered models, additional ¼” phono jacks shall provide paralleled output signals for patching line level outputs to other ampliﬁ er channels.

Ampliﬁ ed outputs shall be connected via three Speakon type jacks, with two jacks providing discrete outputs for channels A and B, and a third jack providing the bridged output on the models capable of bridging channels. On the two higher powered models, there shall be two Speakon type jacks providing discrete outputs for channels A and B.

Attenuation controls for each channel shall be located on the front panel, along with LED signal lamps for each channel showing that the channel is active, and showing fault conditions for DC, temperature, signal presence and automatic clip limiting.

Each model shall also be available with onboard Digital Signal Processing, which shall include delay, parametric equalization, adjustable crossover, adjustable high-pass ﬁ lter, horn EQ and MAXX Bass® low-frequency augmentation per channel.

The multi-channel power ampliﬁ ers shall be the Crest Audio Pro-LITE 2.0, Pro-LITE 3.0, Pro-LITE 5.0, Pro-LITE 7.5, Pro-LITE 2.0 DSP, Pro-LITE 3.0 DSP, Pro-LITE 5.0 DSP and Pro-LITE 7.5 DSP.
