Audio Mixing Console KSM-12
The KSM-12 is a professional audio mixing console designed to manage microphones, instruments, stereo sources, effects, and grouped outputs from one centralized control surface. With 12 Mic/Line channels, sweepable channel EQ, four group outputs, integrated DSP effects, USB media playback, and comprehensive signal monitoring, it provides the routing flexibility required for live performances, conference halls, houses of worship, event venues, studios, and fixed professional audio systems.
Product Description
- 12 Mic/Line input channels: Each input channel includes an independent signal-level LED indicator for convenient gain monitoring and source management.
- Additional stereo connectivity: Two stereo input channels support music players, keyboards, computers, and other stereo programme sources.
- Three-band channel equalizer: High, sweepable mid, and low-frequency controls allow individual sources to be shaped for greater clarity and balance.
- 80 Hz low-cut filter: The integrated high-pass filter helps remove microphone handling noise, stage rumble, and unnecessary low-frequency energy.
- Flexible AUX routing: Three AUX outputs and two AUX FX send outputs support monitor mixes, external processors, and additional audio zones.
- Four-group mixing architecture: Four group outputs allow related channels to be controlled together, simplifying management of vocals, instruments, or speaker zones.
- Integrated DSP effects: The built-in processor provides 100 preset effects for adding reverb, delay, and other processing without external equipment.
- Seven-band stereo graphic EQ: The switchable master equalizer allows the overall system response to be adjusted for different loudspeakers and room acoustics.
- Comprehensive signal monitoring: LED level meters with PFL/AFL monitoring provide visual feedback for Group 1/2, Group 3/4, and Main L/R buses.
- USB media playback: The integrated player supports WAV, WMA, APE, FLAC, and MP3 audio formats, together with OTG functionality.
- Multiple professional outputs: Includes Main L/R, four group outputs, group-room monitoring, return inputs, and dedicated effect routing.
