The SVEN SPS-517 and SPS-575 are 2.0 USB Multimedia Speaker Systems designed for playing music and providing audio for games, movies, and other multimedia content. These speaker systems feature a built-in amplifier, an audio cable, and a signal cable, allowing them to connect to a wide range of audio sources such as PCs, laptops, MP3 players, and CD players. Power is supplied via a USB port from a PC, laptop, or a 5V DC power supply using the integrated USB cable. The speaker unit that includes the audio input and control panel is referred to as the "active speaker."
Function Description:
The primary function of the SVEN SPS-517 and SPS-575 speaker systems is to reproduce audio from various sources. They are designed to enhance the audio experience for users of computers, media players, and mobile devices. The integrated amplifier ensures that the audio signal is boosted to an audible level, while the 2.0 channel configuration provides stereo sound. The systems are plug-and-play with common audio sources, making them easy to set up and use.
Important Technical Specifications:
- Output Power (RMS): Both models deliver 6 W (2 x 3 W). This indicates the continuous power output per channel.
- Frequency Range:
- SPS-517: 100 – 20,000 Hz. This range covers most audible frequencies for general audio playback.
- SPS-575: 80 – 20,000 Hz. The SPS-575 offers a slightly extended low-frequency response compared to the SPS-517, potentially providing deeper bass.
- Speaker Diameter:
- SPS-517: 60 mm.
- SPS-575: 23 + 75 mm. The SPS-575 likely features a two-way design with a smaller tweeter (23 mm) and a larger woofer (75 mm) for better frequency separation and sound quality.
- Power Supply: USB/DC 5V for both models. This allows for convenient powering directly from a computer's USB port or a standard 5V DC power adapter.
- Dimensions (one speaker) (W × H × D):
- SPS-517: 98 × 141 × 97 mm. These are compact dimensions, suitable for desktop use.
- SPS-575: 120 × 185 × 120 mm. The SPS-575 is slightly larger, consistent with its potentially larger drivers.
- Weight:
- SPS-517: 0.75 kg.
- SPS-575: 1.10 kg. The SPS-575 is heavier, which could be due to larger drivers and/or a more robust cabinet construction.
- Cabinet Material: Wood (MDF) for both models. MDF (Medium-Density Fiberboard) is a common material for speaker cabinets, known for its acoustic properties that help reduce resonance and improve sound clarity.
Usage Features:
- Compatibility: The speaker systems are compatible with PCs, DVD/Media-players, mobile devices, and other sound sources, offering versatility in their application.
- USB-Powered: The ability to be powered via a PC/laptop USB port or a 5V DC power supply makes them highly portable and convenient, eliminating the need for a separate power adapter in many scenarios.
- Volume Control: A dedicated volume control knob (labeled as ② on the control panel) allows users to easily adjust the overall sound level. Turning the knob clockwise increases the volume, while turning it counterclockwise decreases it.
- Power LED: An indicator light (labeled as ① on the control panel) shows the power status of the device.
- Easy Connection: The active speaker has a built-in 3.5 mm mini-jack signal cable for connecting to the audio output of a source device. The USB power cable is also integrated.
- Speaker Placement: For optimal sound, the speakers should be placed symmetrically to the listener, at least one meter away. It is also recommended to place them away from monitors and TV sets to avoid potential image distortion on supersensitive displays.
- Setup Procedure:
- Ensure the MSS is unplugged before connecting.
- Insert the 3.5 mm mini-jack signal cable from the active speaker into the audio output of your sound source.
- Set the master volume level to its minimum by turning the volume control knob counterclockwise.
- Plug the USB cable into a USB port on your PC/laptop or a 5V DC power supply.
- Adjust the master volume to the desired level using the volume control knob.
- After use, it is recommended to unplug the MSS.
Maintenance Features:
- Safety Precautions:
- Do not open the MSS or attempt repairs yourself. All servicing should be performed by qualified specialists at authorized service centers.
- Avoid short-circuiting the wires between speakers, on the power amplifier, or to the ground, as this can damage the power amplifier output stage.
- Prevent foreign objects from entering the speaker holes.
- Protect the MSS from high humidity, water, and dust.
- Keep the speakers at least 1 meter away from heat sources and out of direct sunlight.
- Do not place any open flame sources near the system.
- Cleaning: Use only a dry, soft cloth for cleaning. Do not use chemical agents, as they can damage the decorative surface of the MSS.
- Troubleshooting: A dedicated section in the manual provides solutions for common issues such as the MSS not turning on, no sound or quiet sound, and sound distortion. If these steps do not resolve the problem, users are advised to contact a service center rather than attempting self-repair.
- Transportation: Shipping and transportation of the equipment should only be done in the original container to prevent damage.
- Storage: The device does not require special storage conditions for realization.
- Disposal: Dispose of the equipment in accordance with local regulations for household and computer equipment.
- Initial Setup after Cold Exposure: If the speaker system has been in a cold environment, it should be kept at room temperature for at least 4 hours after unpacking before being switched on.
