600W × 2 Power for Larger Karaoke Systems
The AC S-600 delivers:
600W × 2CH @ 8Ω
providing substantially more amplifier headroom for demanding 10-inch and 12-inch passive karaoke speakers.
The additional output power makes the S-600 an excellent choice for larger living rooms, dedicated home KTV rooms, entertainment spaces, and medium-size karaoke installations where more output and dynamic headroom are required.
Because the power amplifier and karaoke DSP are integrated into one unit, a typical system can be kept simple:
Karaoke Player → AC S-600 → Passive Karaoke Speakers
Add a TV or projector for lyrics and video, and an active subwoofer when additional low-frequency impact is desired.
15-Band Microphone Parametric EQ
The S-600 features advanced microphone processing built specifically for karaoke vocal tuning.
A full 15-band microphone parametric EQ provides precise adjustment of:
Compared with basic bass, mid, and treble controls, a 15-band PEQ gives installers much finer control over vocal warmth, clarity, presence, brightness, and problem frequencies.
This is especially useful when matching different microphones, speakers, and room acoustics.
The microphone section also includes:
- Microphone High-Pass Filtering
- Microphone Level Control
- 4-Level Feedback Suppression
Together, these tools help create 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.
Each band provides adjustable Frequency, Q, and Gain, allowing music to be tuned independently from the microphones.
Additional music controls include:
- Music Source Selection
- Key / Pitch Adjustment
- Music Exciter
- Independent Music Level
This separation between music and microphone processing is particularly important in karaoke, where the ideal vocal response and music response are often very different.
Professional Echo & Reverb Processing
The S-600 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 includes its own 3-band parametric EQ, allowing Echo and Reverb to be shaped independently from the original microphone signal.
This makes it possible to create anything from a clean, natural vocal effect to a fuller and more spacious traditional KTV sound.
Independent Main Output DSP
One of the most useful features of the S-600 is its dedicated Main Output processing section.
After the individual Music, Microphone, and Effect settings have been adjusted, the Main Output DSP provides an additional stage for matching the complete system to the speakers and room.
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 additional output-stage control gives installers greater flexibility when tuning different speaker systems and room environments.
Independent Center Output Processing
The S-600 provides a dedicated DSP section for a Center output.
Available controls 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 installations that require more focused vocal coverage.
Dedicated Subwoofer DSP
A separate Subwoofer DSP section allows an active subwoofer to be integrated with the main karaoke speakers.
Subwoofer processing includes:
- Independent Subwoofer Level
- Music / Vocal / Effect Level Control
- High-Pass Filter
- Low-Pass Filter
- Delay
- 3-Band Parametric EQ
This allows the low-frequency response and crossover point to be adjusted without requiring a separate external DSP or electronic crossover.
4-Level Feedback Suppression
Microphone feedback is one of the most common problems in karaoke systems.
The S-600 includes four selectable levels of feedback suppression, allowing the amount of processing to be matched to the room, speaker placement, microphone position, and required singing volume.
This helps reduce microphone squeal while maintaining a more natural vocal sound.
6 Programmable Karaoke Sound Presets
The AC S-600 can store up to 6 programmable sound presets.
Different presets can be created for:
- Different singing styles
- Different vocal preferences
- Different room environments
- Different speaker systems
- Karaoke and entertainment applications
Once the system has been professionally tuned, everyday users do not need to adjust 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.
This makes everyday operation much easier than traditional amplifiers that rely entirely on small buttons and complex menus.
Advanced parameters can remain professionally configured while normal users simply adjust volume, select modes, and enjoy the system.
Professional PC DSP Tuning
For installers and advanced users, the S-600 can be connected to a Windows computer for detailed DSP configuration.
Available 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
- 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 wirelessly from compatible smartphones, tablets, and other Bluetooth audio devices.
The S-600 can also be integrated with karaoke players, TVs, and other home entertainment sources as part of a complete KTV system.
