4 Channels C lass D Power Amplifier
DJ 04 series
The DJ 04 s eries are the best solution for those space-constricted installed sound reinforcement applications where sonic quality and system performance are required on a long-term full-power operating basis. Implementing SAE highefficiency Class D power modules , the D J 04 amplifiers provide an unprecedented acoustic fidelity on the high- power sound amplifiers range.
Features High efficiency Class D power modules. Power Factor Correction technology Highly sensitive CMRR balanced inputs for improved noise rejection. XLR input and signal link connectors. SpeakON NL4 and binding post output connectors. Input sensitivity selector on the back panel (32dB / 1V / 0.775V) . Routing mode selector on the back panel (stereo / bridgeparallel). Channel independent temperature, protection and clip warning indicators on the front panel. Channel independent power and -5dB / -10dB / -20dB / signal presence indicators on the front panel.
Applications Mobile / portable public address or monitoring amplification. DJ sound system. Small sized bar / café / lounge installation. Applications with signal processing requirements.
Technology Class D SAE Audio Class D technology implements the most advanced electronics within the smallest form-factor amplifier modules. The Class D amplifiers by SAE Audio implement the most efficient sound amplification technology available today, providing an unmatched system portability and affordability with the best sonic performance.
Power Factor Corrector SAE Audio innovative Power Factor Correction (PFC) technology along with its renowned R-SMPS power supply allows to drawn current from the mains in a more efficient way translating to a higher output power with a lower power consumption. Additionally PFC improves audio quality; it generates lower harmonics of the mains frequency thus reducing the hum and induced distortion because of perturbed mains.
Aluminum Unibody
HS-CMRR balanced inputs The best signal quality at an amplifier output can only be achieved with the best signal quality at its input. With the DJ 04 series is not a problem to have long signal input cables along with power lines or other induced noise sources. The balanced signal inputs on the DJ 04 amplifiers implement a High Sensitivity CMRR (Common Mode Rejection Ratio) design in order to reject even the slightest added distortion on the signal, thus assuring the best possible audio signal at the input.
SAE Audio next generation of audio power amplifiers are built into the most advanced ever 19” rack enclosure design. The Alu-Body chassis has been engineered to enhance the device protection, the thermal dissipation performance, and reduce the overall weight. Its cur ved lateral edges provide a wider surface in order to reduce the pressure applied in case of an impact, and the front and rear panels are protected within the same amplifier cover. Compared to traditional steel amplifier chassis the new full aluminum Alu-body design significantly reduces the amplifier weight, making it much more convenient to transport or install on mobile applications, and increases the thermal dissipation further improving the amplifier power efficiency.
