The mono class D PA power amplifier PA-1250D is part of a new generation of equipment which combines a high power capability with an efficient energy utilisation, thus making an important contribution to climate protection. Furthermore, the user also saves electricity costs. Among other things, this is due to the digital 100V power amplifier providing a considerably higher efficiency of more than 90% compared to analogue units (approx. 70%). Furthermore, the thermal loss is considerably lower. Thus, the cooling requirements will be minimised and the service life of the PA-1250D will be further increased.
Features- 1 x 250 W
- Class D concept with a high efficiency of more than 90% to cut energy costs
- Additional integrated energy-saving functions, e.g. device automatically goes to standby mode when no input signal is present (as soon as an input signal is detected, the amplifier is automatically switched on again)
- Requires a significantly lower rechargeable battery capacity for emergency power operation than 100 V analogue amplifiers
- Clearly reduced cooling requirements due to low heat dispersion
- Silent operation due to fanless cooling concept, thus especially suitable for noise-sensitive areas, e.g. offices, conference rooms or churches
- Special protective circuits prevent damage caused by short circuit or overheating
- Extensive, menu-controlled settings
- Switchable 200 Hz high-pass filter, 6 dB/oct.
- Additional priority input
- LCD for the operating parameters
- Mains operation or 24 V emergency power operation
