1. Bridging Configuration: The QM4 allows bridging of channels 3&4 (and 1&2), but the polarity for the speaker wires is non-standard compared to competitors.
2. Input Sensitivity (Gain) Range: The manual provides the specific voltage range (typically 0.2V to 6V) to match your head unit’s pre-out voltage. Overlooking this causes clipping.
3. Crossover Multipliers: The QM4 has a bass boost circuit and a variable LP/HP filter. The manual includes a frequency multiplier chart that is not printed on the amplifier chassis.
4. LED Diagnostic Codes: The power/protect LED blinks in specific patterns. Only the manual translates these patterns (e.g., 2 blinks = short circuit, 3 blinks = thermal overload).
