2 Sweep Hz

The Sweep Hz control selects the upper range cutoff frequency of the SUB120’s internal electronic crossover. The SUB120’s crossover provides a 12dB per octave Linkwitz Riley filter curve. The Sweep adjusts the highest frequency that the SUB120 will reproduce, and at the same time, the high-pass outputs track the selected crossover frequency as the lower limit frequency to the satellite speakers.

3 Power/Protect LED

The POWER/PROTECT LED is a dual color LED which has three states; OFF, GREEN AND RED. The following chart shows the POWER/PROTECT LED and the different operating conditions it represents.

If the SUB120 receives a clipped signal for a long duration of time the unit will shut down and enter PROTECT mode. When the SUB120 is in Protect, you will see the POWER /PROTECT LED is lit up in red. If this happens simply turn the unit off, wait a minute and then re-power up the unit. The LED should return to a green color again indicating normal operation . At this point, readjust the level you’re sending to the SUB120 so that the signal is not clipped and the unit will operate properly.

4Auto On Switch

The AUTO ON switch is used to select the SUB120’s power operating mode. When the switch is set to OFF the unit is not operational. When the AUTO ON switch is set to the ON position, the unit is always on. To engage the SUB120’s SLEEP function, slide the AUTO ON switch to the AUTO position. In this mode, the SUB120 enters a stand-by, or "SLEEP" condition after no input signal is sensed for a period of approximately 10 minutes. The SUB120 will return to the normal operating mode as soon as it senses a signal present at the inputs.

5Phase Switch

The SUB120 can be switched for inverted phase operation by setting the PHASE SWITCH to the 180° (degree) position. Experiment with this switch to provide the best blend between the subwoofer and satellite speakers.

6The Ins and The Outs

The SUB120 features both line level and speaker level inputs and outputs so that connection with passive or active satellites is easy. The PREAMP LEVEL INPUTS simply pass the line level signal through to the PREAMP LEVEL OUTPUTS. You can use the line inputs and outputs to interface the SUB120 with active monitors. The SPEAKER LEVEL INPUTS can be connected from the speaker outputs of a power amplifier, and then the signal is sent from the SPEAKER OUTPUTS, which are high-passed, to passive satellite speakers. The following sec- tions of this manual detail the set-ups for many typical configurations with both passive and active monitors. In addition, there is a detailed cable wiring diagram on page 15.

Sub120 specifications

The Samson Sub120 is a compact yet powerful subwoofer designed for both professional audio applications and high-fidelity home entertainment systems. Engineered with innovative technologies and robust features, the Sub120 aims to deliver deep, impactful bass that enhances the overall listening experience.

At the heart of the Sub120 is its 12-inch low-frequency driver, specifically designed to reproduce low-end frequencies with accuracy and depth. This driver is crafted to produce a wide frequency response, typically ranging from 25 Hz to 150 Hz, allowing for a rich sound that can handle everything from thundering explosions in movies to the subtle nuances of acoustic music.

One standout feature of the Samson Sub120 is its built-in high-efficiency amplifier, which provides a peak power output of around 400 watts. This ensures that the subwoofer can fill a room with sound without distortion, even at higher volume levels. The amplifier is designed to work synergistically with the driver, optimizing performance and providing a seamless listening experience across various audio formats.

The Sub120 also incorporates adjustable crossover settings, enabling users to tailor the audio output to their specific needs. This feature allows for precise control over the frequency range, ensuring that the subwoofer integrates smoothly with other speakers in a surround sound system or home theater setup. Additionally, this flexibility helps in achieving the desired balance between bass and mid/high frequencies, ultimately enhancing the overall sound quality.

Connectivity is made easy with the Sub120, as it offers multiple input options, including XLR, TRS, and RCA connections. This versatility ensures compatibility with a wide range of audio equipment, making it suitable for both live performances and studio environments. Furthermore, the Sub120 is equipped with a Phase switch, which allows users to adjust the phase alignment with other speakers, aiding in creating a cohesive soundstage.

The design of the Sub120 is another notable aspect. It features a rugged, yet stylish cabinet that not only enhances its aesthetic appeal but also contributes to the durability of the unit. The front-firing port design helps to maximize bass response while minimizing port noise, further elevating the listening experience.

Overall, the Samson Sub120 is a remarkable subwoofer that combines advanced technology, user-friendly features, and robust build quality. Whether used in professional settings or for home audio, it is designed to deliver powerful, deep bass response that complements any audio system.
