DIGAM - Q series
The evolution of DIGAM technology for a wide range of 4 channels uses
DIGAM Q Series offer various power ratings in 5 models ranging from 4 x 400 watts/ch. @ 4 Ohm to 4 x 1250 watts/ch. @ 2 Ohm, still maintaining the 1 unit size.
This series, in similar way to the corresponding D series, is particulary suitable to be used either for stand alone medium/small installations either in large and distributed systems tanks to the capability of advanced remote control and monitoring features suitable to manage up to 100 amps.
The Q series represents a further flexible and cost effective approach from stand alone use to large systems, allowing in various system configurations to reduce the total number of equipments.
Features
- Advanced switch-mode worldwide operating power supply technology for high performance and compact size
- Power Factor Correction PFC for extremely low mains consumption and wide mains operating range
- Variable speed fan for low noise
- Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
- XLR female / 6.3mm Jack Neutrik style input connectors with link capability
- Built-in Clip limiters
- Detented gain controls for fast and accurate gain settings
- Comprehensive front panel indicators including signal, clip, protect and thermal forecast
- Fully protected circuitry design including DC, infrasonic, high frequency, thermal overload and short circuit
- Fixed frequency switchmode output stage for high grade sound accuracy
- Compact size - all models only 1 RU for reduced rack cost and space
- Light weight - all models only 10 kg (22 pounds) for easier racking and shipping
- Remote Control Option ( RS 485 interface )
Protections circuitry
DC protection: protects against infrasonic signals and output stage fault
VHF protection: protects the loudspeakers against strong very high frequency non-musical signals above the audible range.
Thermal protection: prevents the amplifier from being overheated. The protection indicators on the front panel are switched on, as a warning, before the protection process is initiated.
AC protection: shuts down the power supply if the line voltage is outside the operating voltage.
Clip limiter: prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power.
