Soundmax SX-N Series Amplifiers
This document serves as a user manual for the Soundmax SX-N series of amplifiers, including models SX-N300.4, SX-N400.4, SX-N500.4, SX-N600.4, and SX-N700.4.
Amplifier Controls and Connections
The following controls and connection points are typically found on the Soundmax SX-N series amplifiers:
- HI-INPUT (CH1/2/3/4): High-level speaker wire inputs for connection to head units without RCA pre-outs.
- INPUT-signal input, RCA jacks: Standard RCA line-level inputs for connecting audio sources.
- GAIN: This control adjusts the input signal level sensitivity, typically ranging from 0.2V to 6V, to match the output of the audio source.
- HPF (High-Pass Filter): Allows adjustment of the crossover frequency for the high-pass filter, typically ranging from 100Hz to 1KHz. This filters out low frequencies.
- LPF (Low-Pass Filter): Allows adjustment of the crossover frequency for the low-pass filter, typically ranging from 40Hz to 400Hz. This filters out high frequencies.
- X-OVER: Refers to the crossover frequency selection, often linked to the HPF and LPF controls.
- BASS BOOST: A feature that provides a selectable boost to the low bass frequencies.
- POWER/PROTECT LED:
- Blue LED: Indicates the amplifier is powered on and operating normally.
- Red LED: Indicates the amplifier is in protection mode (e.g., due to overheating, short circuit, or DC offset).
- CLIP LED: An orange LED that illuminates when the audio signal is clipping, indicating the input gain is set too high and distortion is occurring.
- 2CH/4CH SIGNAL INPUT SELECTION: A switch to select the input mode. '4CH' typically means channels 1/2 inputs are used for channels 1/2 and channels 3/4, while '2CH' might use specific inputs for a 2-channel configuration.
