Diagram Description: A visual representation of the amplifier's dimensions, showing labels A through F corresponding to specific lengths, widths, and hole positions. Label A indicates the chassis length, A-1 and A-2 specify mounting hole locations and distances, A-3 is the overall length, and A-4 marks the power terminal length. Label B denotes the overall width, C the overall height, and D indicates the width for mounting hole locations. E shows the diameter of the mounting holes, and F indicates the width of the mounting holes.
Technical Graph Data
THD+N vs. Power (W) @14.4VDC
This graph illustrates the Total Harmonic Distortion plus Noise (THD+N) ratio as a percentage against the power output in Watts at a supply voltage of 14.4VDC. It shows data for 1Ω, 2Ω, and 4Ω impedance loads. Generally, THD+N increases as power output rises, particularly at higher power levels.
Power Bandwidth (4Ω) @14.4VDC
This graph displays the power bandwidth for a 4Ω load at 14.4VDC, referenced to the rated power of 900W. It shows the frequency response (in Hz) on the x-axis and the level in decibels relative to the rated power (dBrA) on the y-axis. The curve indicates the frequency range over which the amplifier maintains its rated output power with minimal deviation.
FFT (50Hz Signal)
This graph presents the Fast Fourier Transform (FFT) analysis of a 50Hz input signal. The x-axis represents frequency in Hertz (Hz), and the y-axis shows the signal level in decibels relative to voltage (dBV). The plot reveals the fundamental 50Hz frequency and the presence of harmonics and noise across the spectrum.
Crossover Frequency Response
This graph illustrates the frequency response of the amplifier's crossover filters. It shows two curves: one for a 200Hz Low Pass Filter (LPF) and another for a 50Hz Low Pass Filter (LPF). The x-axis is frequency in Hz, and the y-axis is the level in dBrA. The curves demonstrate how the filters attenuate frequencies above their set points.
KickEQ™
This graph shows the effect of the KickEQ™ variable bass boost feature at 40Hz. It compares the frequency response with the bass boost turned OFF and with a +6dB bass boost engaged. The x-axis represents frequency in Hz, and the y-axis shows the level in dBrA. The graph highlights the boost applied to low frequencies.
