Commandes et connexions
The Dayton Audio SA100 amplifier features a comprehensive set of controls and connection options on its rear panel. Understanding these will ensure proper setup and optimal performance.

Figure 1 : Labeled diagram of the SA100 amplifier rear panel, showing all controls and connections.
- Entrées de bas niveau (RCA) : These inputs are used to connect the amplifier to the low-level (line-level) output of your receiver or preamplifier. Use a Y-adapter if your source has a single mono subwoofer output to ensure full power output.
- Low-Level Outputs (RCA): These outputs allow you to pass the low-level signal to another ampamplificateur ou appareil.
- High-Level Inputs (Speaker Level): Connect these inputs to the speaker outputs of your main amplifier or receiver. This is useful if your source unit does not have dedicated low-level outputs. Connect the left and right channels from your main amplifier to the corresponding 'FROM AMPLIFIER' terminals.
- High-Level Outputs (Speaker Level): These outputs allow you to pass the full-range speaker signal to your main speakers. Connect your main speakers to the 'TO SPEAKERS' terminals.
- Puissance d'entrée : Connect the supplied AC power cord here. Ensure the voltage matches your local power supply (120VAC, 60Hz).
- Speaker Output (Internal): These wires connect internally to your subwoofer driver. Ensure correct polarity (+ to + and - to -) for proper operation.
- Gain Control: This knob adjusts the overall output volume of the subwoofer. Start with a low setting and gradually increase until the subwoofer output blends seamlessly with your main speakers.
- Power/Protection Indicator: This LED illuminates to indicate the amplifier's operational status. It typically glows green during normal operation and may change color or flash to indicate a protection mode.
- Frequency (Crossover) Control: This knob adjusts the low-pass crossover frequency from 40Hz to 180Hz. This determines the highest frequency the subwoofer will reproduce. Adjust it to blend smoothly with your main speakers, typically set slightly above the lowest frequency your main speakers can reproduce.

- Auto On/Off Switch: This three-position switch controls the ampÉtat d'alimentation du répéteur.
- SUR: Le amplifier is continuously powered on.
- VOITURE: Le ampL'amplificateur s'allumera automatiquement lorsqu'un signal audio sera détecté et passera en mode veille après une période sans signal.
- OFF: Le amplificateur est éteint.

Figure 3 : Detail of the Auto On/Off switch.
- Interrupteur de phase : This two-position switch (REV/NOR) adjusts the phase of the subwoofer output by 180 degrees. Experiment with both settings to find the one that provides the most impactful and coherent bass response with your main speakers.

Configuration et installation
Proper installation is crucial for the performance and safety of your SA100 amplifier. Cette amplifier is designed to be mounted into a custom subwoofer enclosure.
Montage du Amplifier
- Enclosure Preparation: Ensure your subwoofer enclosure has a cutout that matches the dimensions of the SA100 amplifier's mounting plate. The product dimensions are 4.72 x 8.66 x 7.48 inches.
- Câblage interne : Connect the internal speaker wires (6) from the amplifier to your subwoofer driver. Observe correct polarity: red to positive (+) and black to negative (-).
- Montage sécurisé : Insérez soigneusement le amplifier into the cutout. Use appropriate screws to secure the amplifier plate firmly to the enclosure, ensuring an airtight seal.
Connexion à votre système audio
Choose one of the following connection methods based on your audio system's capabilities:
Method 1: Using Low-Level (RCA) Inputs
- Connect an RCA cable from the subwoofer output (LFE output) of your receiver or preamplifier to the Low-Level Inputs (1) on the SA100.
- If your receiver has only one LFE output, use an RCA Y-adapter to connect to both L and R Low-Level Inputs on the SA100 for optimal performance.
Method 2: Using High-Level (Speaker Level) Inputs
- Connect speaker wires from the speaker outputs of your main amplifier or receiver to the High-Level Inputs (3) on the SA100. Ensure correct polarity.
- If you wish to pass the signal to your main speakers, connect speaker wires from the High-Level Outputs (4) on the SA100 to your main speakers.
Connexion électrique
- Once all audio connections are made, connect the supplied AC power cord to the Power Input (5) on the ampl'amplificateur, puis vers une prise murale appropriée.
Mode d'emploi
Follow these steps to power on and adjust your SA100 amplifier for optimal sound.
- Mise sous tension : Set the Auto On/Off switch (10) to 'ON' or 'AUTO'. The Power/Protection Indicator (8) should illuminate.
- Réglage initial du gain : Set the Gain control (7) to its minimum position (fully counter-clockwise).
- Réglage de la fréquence de coupure : Set the Frequency (Crossover) control (9) to a starting point, typically around 80Hz-100Hz. This will depend on the low-frequency capabilities of your main speakers.
- Ajustement des phases : Set the Phase switch (11) to 'NOR' (Normal).
- Lire l'audio : Begin playing audio through your system at a moderate listening level.
- Ajuster le gain : Slowly increase the Gain control (7) on the SA100 until the subwoofer's output blends smoothly with your main speakers. The subwoofer should not sound overly loud or localized.
- Fine-tune Crossover: Adjust the Frequency (Crossover) control (9) to achieve the best blend between the subwoofer and your main speakers. The goal is a seamless transition without a noticeable gap or overlap in frequencies.
- Phase d'ajustement : Experiment with the Phase switch (11) in both 'NOR' and 'REV' positions. Choose the setting that provides the most impactful and coherent bass response at your listening position. This often involves listening for the strongest and clearest bass.
- Auto On/Off (Optional): If you prefer the amplifier to power on and off automatically with your audio system, set the Auto On/Off switch (10) to 'AUTO'. The amplifier will enter standby mode after approximately 15-20 minutes of no audio signal.
