AC S-800 Smart Karaoke Mixing Amplifier – 800W × 2
The AC S-800 is the highest-power model in the AC S-Series, combining an 800W × 2-channel power amplifier, professional karaoke DSP processor, 4.3-inch touchscreen, Bluetooth 5.0, advanced microphone processing, feedback suppression, and independent output DSP control in one integrated unit.
Designed for home KTV, dedicated karaoke rooms, entertainment spaces, restaurants, lounges, bars, and commercial karaoke applications, the S-800 provides substantially more amplifier headroom while maintaining the same flexible DSP architecture of the S-Series.
A typical karaoke system can be built simply with:
Karaoke Player → AC S-800 → Passive Karaoke Speakers
Add a TV or projector for video and an active subwoofer when additional low-frequency impact is desired.

Powerful 800W × 2 Amplifier
The AC S-800 delivers:
800W × 2CH @ 8Ω
providing the highest output power in the S-Series.
The additional amplifier headroom makes the S-800 an excellent choice for larger passive karaoke speakers, dedicated KTV rooms, entertainment spaces, and commercial karaoke installations where stronger output and greater dynamic capability are required.
Because the power amplifier and karaoke DSP are integrated into the same unit, the S-800 eliminates the need for a separate external power amplifier in many installations.
15-Band Microphone Parametric EQ
The S-800 features a professional 15-band microphone parametric EQ, providing detailed control over karaoke vocals.
Each EQ band allows adjustment of:
This gives installers precise control over vocal warmth, clarity, presence, brightness, and problematic frequencies.
Compared with traditional bass, mid, and treble controls, the 15-band PEQ provides significantly greater flexibility when matching different microphones, speakers, singers, and room acoustics.
The microphone section also includes:
- Microphone High-Pass Filtering
- Independent Microphone Level
- 4-Level Feedback Suppression
This helps achieve a cleaner, more natural vocal sound while improving stability at higher singing levels.
Independent 7-Band Music PEQ
Music playback is processed separately through a dedicated 7-band parametric EQ.
Frequency, Q, and Gain can be adjusted independently from the microphone section, allowing installers to optimize music playback without changing the vocal tuning.
Additional music functions include:
- Music Source Selection
- Key / Pitch Adjustment
- Music Exciter
- Independent Music Level
Separating music and microphone processing is especially important in karaoke systems because the ideal EQ for music and vocals is rarely the same.
Professional Echo & Reverb Processing
The S-800 includes dedicated DSP processing for karaoke vocal effects.
Adjustable parameters include:
- Echo Level
- Echo Delay
- Echo Repeat
- Reverb Level
- Reverb Delay
- Reverb Time
- Effect Level
- Effect EQ
The Effect section also provides its own 3-band parametric EQ, allowing Echo and Reverb to be tuned independently from the original microphone signal.
This makes it possible to create anything from a clean, natural vocal sound to a fuller and more spacious traditional KTV effect.
Independent Main Output DSP
The S-800 provides a dedicated Main Output DSP section, giving installers an additional stage of system tuning after Music, Microphone, and Effect processing.
Main output controls 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 allows the final system response to be adjusted for different speakers and room acoustics without changing the individual microphone or music tuning.
Independent Center Output DSP
The S-800 also provides a dedicated Center Output processing section.
Available adjustments include:
- Music Level
- Direct Vocal Level
- Echo Level
- Reverb Level
- High-Pass / Low-Pass Filters
- Delay
- Mute
- 3-Band Parametric EQ
This provides additional flexibility for systems using a center speaker or requiring more focused vocal coverage.
Dedicated Subwoofer DSP
The independent Subwoofer DSP section allows an active subwoofer to be integrated directly with the karaoke system.
Available processing includes:
- Independent Subwoofer Level
- Music / Vocal / Effect Level Control
- High-Pass Filter
- Low-Pass Filter
- Delay
- 3-Band Parametric EQ
This allows installers to adjust the subwoofer crossover and tonal balance without requiring an additional external DSP or electronic crossover.
4-Level Feedback Suppression
Microphone feedback is one of the most common challenges in karaoke systems.
The S-800 includes four selectable levels of feedback suppression, allowing processing strength to be matched to the microphone position, speaker placement, room acoustics, and required singing volume.
This helps reduce microphone squeal while maintaining a natural vocal character.
6 Programmable Karaoke Sound Presets
The AC S-800 can store up to 6 programmable DSP presets.
Different presets can be created for:
- Different singing styles
- Different vocal preferences
- Different room environments
- Different speaker systems
- Karaoke and entertainment applications
Once professionally tuned, everyday users do not need to access complicated DSP parameters.
Simply select a preferred preset and start singing.
4.3-Inch Touchscreen Control
The built-in 4.3-inch touchscreen provides convenient access to common system controls and settings directly from the amplifier.
Users can quickly access everyday functions without connecting a computer, while advanced DSP settings remain available through the professional PC tuning software.
This makes the S-800 easy to operate after the system has been properly configured.
Professional PC DSP Tuning
For installers and advanced users, the S-800 can be connected to a Windows computer for detailed DSP configuration.
Professional tuning functions include:
- 15-Band Microphone PEQ
- 7-Band Music 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
- DSP Preset Management
Once tuning is completed, settings can be stored for normal standalone operation.
Bluetooth 5.0 Connectivity
Built-in Bluetooth 5.0 allows compatible smartphones, tablets, and other devices to stream music wirelessly to the S-800.
The amplifier can also be integrated with karaoke players, TVs, and other entertainment equipment as part of a complete home or commercial KTV system.
