Technical Graph Data
AMP1 and AMP2 - THD+N vs. Power (W) @14.4VDC
Graph showing Total Harmonic Distortion plus Noise (THD+N) Ratio (%) versus Power (W) at 14.4VDC for 4Ω Bridged, 2Ω Stereo, and 4Ω Stereo configurations. The graph indicates that THD+N remains low at lower power levels and increases significantly as power output approaches the amplifier's limits.
AMP1 and AMP2 - Power Bandwidth (4Ω) @14.4VDC
Graph illustrating the Power Bandwidth, referenced to Rated Power (100W @ 4Ω), versus Frequency (Hz) at 14.4VDC. The graph shows that the amplifier maintains a consistent output level across a wide frequency range, from approximately 20Hz to 20kHz, with minimal deviation.
AMP1 and AMP2 - FFT (1kHz Signal)
Graph displaying the Fast Fourier Transform (FFT) of a 1kHz signal, showing the level in dBV versus Frequency in Hz. This graph reveals the spectral content of the amplifier's output, including the fundamental frequency and any harmonic distortions or noise components.
AMP1 Crossover Frequency Response
Graph illustrating the crossover frequency response for Amplifier 1. It shows the output level in dBrA across various frequencies for different filter settings: Crossover OFF, 10Hz HPF, 500Hz HPF, 100Hz HPF, 5kHz HPF, 10Hz LPF, 500Hz LPF, 100Hz LPF, and 5kHz LPF. This demonstrates the effectiveness of the high-pass and low-pass filters in shaping the audio signal.
AMP2 Crossover Frequency Response
Graph illustrating the crossover frequency response for Amplifier 2. It shows the output level in dBrA across various frequencies for different filter settings: Crossover OFF, 10Hz HPF, 500Hz HPF, 40Hz LPF, 500Hz LPF, 400Hz LPF, 5kHz LPF, and a 500-5kHz BPF (Band Pass Filter). This highlights the flexibility in configuring the amplifier's frequency filtering.
KickEQ™
Graph showing the effect of the KickEQ™ bass boost feature. It plots the level in dBrA versus Frequency in Hz for both 'Bass Boost OFF' and '+6dB Bass Boost' settings. The graph indicates that the +6dB Bass Boost provides a noticeable increase in low-frequency response, centered around 40Hz.
