LAX R815 เครื่องขยายเสียง 2X2250W/4Ω 2X1450W/8Ω Amplifier,2U
High Class Amplifier Series
The R800 Series of power amplifiers from LAX, utilise a high performance Op-Amp from Onsemi that is made in the USA, and allows the R800 amplifiers to achieve a significantly improveddynamic range.
If you need to drive high power full-range speakers and subwoofers, and you need to do it cleanly, and efficiently, then look no further. We have got it covered, with the R800 Series.
Features
- Utilises a high performance USA-made Onsemi Op-Amp for greater dynamic range
- Sound quality of a Class A amplifier, with the energy efficiency of a Class H design
- Aluminium alloy front panel with a brushed finish and detachable ventilated heat sink panels
- Each channel has an intelligent power supply which can adjust the power output stage
dynamically in real time
- Multiple protection systems; DC, internal fault, input overload, RF interference, short circuit,
impedance mismatch, HF overload, heat, and high current protection
- A unique heat sink, designed in a wind tunnel, provides maximum efficiency
- Extremely low THD
- Conforms to EIA/ECA-310 standard for 19" rack dimensions
