Powerful 400W × 2 Karaoke Amplifier
The S-380 delivers:
400W × 2CH @ 8Ω
providing strong, clean power for many 10-inch and 12-inch passive karaoke speakers.
The amplifier and DSP processor are integrated into the same unit, reducing the number of components required in a typical karaoke installation.
For many home KTV systems, simply connect:
Karaoke Player → AC S-380 → Passive Karaoke Speakers
and connect your TV or display to the karaoke player for video.
15-Band Microphone Parametric EQ
One of the strongest features of the S-380 is its advanced microphone processing.
The microphone section provides a 15-band parametric EQ, allowing much more precise vocal tuning than the basic bass, mid, and treble controls found on conventional karaoke amplifiers.
Each EQ band provides adjustable:
This gives installers detailed control over vocal warmth, clarity, presence, brightness, and problematic frequency areas.
The microphone section also includes multi-level feedback suppression, helping control microphone squeal and improve stability at higher singing levels.
7-Band Music Parametric EQ
Music playback has its own independent 7-band parametric EQ.
Frequency, Q, and Gain can be adjusted separately, allowing the music response to be optimized for different speakers and room acoustics without changing the microphone sound.
Additional music controls include:
- Music Source Selection
- Key / Pitch Control
- Music Exciter
- Independent Music Level
This separation between music and microphone processing gives the S-380 much greater tuning flexibility than a basic mixing amplifier.
Professional Echo & Reverb Processing
The S-380 includes dedicated DSP processing for karaoke vocal effects.
Adjustable parameters include:
- Echo Level
- Echo Delay
- Echo Repeat
- Reverb Level
- Reverb Delay
- Reverb Time
- Effect EQ
The effect section also includes its own 3-band parametric EQ, allowing the tonal character of Echo and Reverb to be adjusted independently from the original microphone signal.
This makes it possible to create anything from a clean, natural vocal to a fuller and more spacious traditional karaoke sound.
Independent Main Output DSP
Unlike many integrated karaoke amplifiers, the S-380 provides dedicated processing for the Main Output.
Main output adjustments include:
- Music Output Level
- Direct Vocal Level
- Echo Level
- Reverb Level
- High-Pass Filter
- Low-Pass Filter
- Left / Right Mute
- Left / Right Delay
- 3-Band Main Output Parametric EQ
This gives installers an additional tuning stage for matching the amplifier to the speakers and room after the individual music, microphone, and effect settings have been adjusted.
Independent Center & Subwoofer DSP
The S-380 also includes dedicated processing for Center and Subwoofer outputs.
Center Output
The center section provides:
- Independent Music Level
- Direct Vocal Level
- Echo Level
- Reverb Level
- High-Pass / Low-Pass Filtering
- Delay
- Mute
- 3-Band Parametric EQ
This provides additional flexibility for systems using a center speaker or requiring more focused vocal coverage.
Subwoofer Output
The dedicated subwoofer section provides:
- Independent Subwoofer Level
- Music / Vocal / Effect Level Control
- High-Pass / Low-Pass Filtering
- Delay
- 3-Band Parametric EQ
This allows an active subwoofer to be properly integrated with the main karaoke speakers without requiring a separate external DSP processor.
6 Programmable Sound Presets
The AC S-380 can store up to 6 sound presets for quick recall.
Different presets can be configured for different:
- Singing styles
- Speaker systems
- Room environments
- Vocal preferences
- Karaoke / entertainment applications
Once professionally tuned, users do not need to adjust complicated DSP parameters during normal use.
Simply select the desired preset and start singing.
4-Level Feedback Suppression
Microphone feedback is one of the most common problems in karaoke systems.
The S-380 includes built-in feedback suppression with four selectable processing levels, allowing the system to be adjusted according to the room, microphone position, speaker placement, and required sound pressure level.
This helps achieve higher usable microphone volume while reducing unwanted squeal and feedback.
4.3-Inch Touchscreen Control
A built-in 4.3-inch touchscreen provides convenient access to everyday system controls and settings.
The touchscreen makes the S-380 easier to operate than traditional amplifiers that rely entirely on small buttons and complicated menu combinations.
Once the system has been professionally configured, normal users can operate the amplifier without needing to access the advanced PC tuning software.
Professional PC DSP Tuning
For installers and advanced users, the S-380 can be connected to a Windows PC for detailed DSP configuration.
Professional tuning functions include:
- 7-Band Music PEQ
- 15-Band Microphone PEQ
- 3-Band Effect PEQ
- 3-Band Main Output PEQ
- 3-Band Center Output PEQ
- 3-Band Subwoofer PEQ
- Echo & Reverb Adjustment
- Feedback Suppression
- High-Pass / Low-Pass Filters
- Output Delay
- Channel Level Control
- Preset Management
Once tuning is complete, settings can be stored for normal standalone operation.
Bluetooth 5.0 Connectivity
Built-in Bluetooth 5.0 allows music to be streamed directly from compatible smartphones, tablets, and other Bluetooth audio devices.
The S-380 can also be integrated with karaoke players, TVs, and other home entertainment sources as part of a complete KTV system.
