    Could someone go through this thing line by line to help me understand all this jiberish. I'm not very good at amp lingo,

    Continuous Power Rating
    8 Ohms: 500 W

    4 Ohms: 750 W

    2 Ohms: 1200 W

    8 Ohms Bridged Mono: 1500 W

    4 Ohms Bridged Mono: 2400 W

    Current Consumption: 10 Amps

    Distortion (Typical):
    20 Hz-20 kHz: 10 dB below rated power Less than 0.03% THD 4 and 8 ohms
    1.0 kHz and below: full rated power Less than 0.03% THD 4 and 8 ohms

    Frequency Response: 20 Hz-20 kHz, +/- 1 dB, -3 dB points: 5 Hz-50 kHz

    Damping Factor, 1 kHz and below: Greater than 300 at 8 ohms

    Input Impedance: 10 k ohms unbalanced, 20 k ohms balanced

    Input Clipping: 10 Vrms (+22 dB)

    The above are per-channel ratings with the specified load on each channel.

    The two above are for the unit switched to "bridge mono" with the switch presumably present somewhere, and with the load connected between the "hot" terminals of the two channels.

    That indicates that when producing a typical power of 1/8 maximum, it draws about 10A. That seem high, so they may be using a higher power. In any case, it indicates a 20A circuit should work, if you don't pound it too hard.

    The above distortion ratings indicate they aren't real proud of their specs. The power supply may be a bit weak, since they only rate distortion at an "easy" frequency of 1k Hz at full power

    Plenty good enough, refers to the range of frequencies that can be amplified. That covers the whole audible range, and is fine.

    Acceptable performance, indicates how well it will control speaker movement , particularly at low frequencies. Its fine.

    Normal, any line output can drive it OK if it has enough voltage output

    If you drive it with a really hot input signal over 10 volts , something inside may clip (distort) even if the gain control is down and the amp itself is putting out a low volume to the speaker.
