The Celto Acoustique SQ12000 is a four-channel touring amplifier delivering up to 12kW RMS from a single rack unit. It belongs to Celto's S Series, built specifically for the demands of live production, and pairs very high power density with the kind of measured performance normally associated with studio equipment.
Power Output
- 4 x 1800W into 8 ohms
- 4 x 3000W into 4 ohms
- 4 x 2600W into 2 ohms
Why It Performs
Active PFC with resonant SMPS. The switch-mode supply uses active power factor correction, which keeps current draw clean and allows this much output from a 1U chassis without the mains behaviour that plagues conventional designs.
TrueSound Class D output stage using high-speed, high-current MOSFETs. Efficiency without the softness at the frequency extremes that Class D was once known for.
Zero-attack J-FET limiting. The limiters engage transparently rather than clamping audibly, so the amplifier protects your drivers without the listener hearing it work.
Studio-grade input stage with MUSE Fine Gold capacitors and ultra-low-distortion op-amps, backed by long-life Japanese electrolytics throughout every stage.
Measured Performance
- THD+N below 0.03% across 20Hz to 20kHz
- Signal-to-noise 107dB(A), with background noise at -110dB
- Frequency response 5Hz to 20kHz (±0.1dB)
- Damping factor above 800 at 8 ohms, 500Hz
- Slew rate above 60V/µs
- Crosstalk better than 75dB at 1kHz
Frequency and phase response remain flat regardless of load, so the amplifier behaves predictably across different cabinet configurations.
Connectivity & Build
- Inputs: 4 x balanced Neutrik XLR, 20 kOhm impedance, +20dBu maximum
- Outputs: 4 x Neutrik speakON NL4MP
- Cooling: temperature-regulated brushless fans, front-to-back airflow
- Protection: short circuit, over- and under-voltage, over-current, overload and thermal
- Operating voltage: 90–260V AC
- Chassis: 1U, 482 x 45 x 281mm, 10kg net
Who It Is For
Suited to touring companies, production houses, installers and venue operators driving multi-way systems or subwoofer arrays. The shallow-depth 1U chassis and 10kg weight matter on the road, where rack space and case weight are real constraints. Four independent channels mean a single unit can drive a complete left-right system with tops and subs.
