Description

Four-channel amplifiers with an NL4 panel and a height of only 2 HE are offered for sale. EP5 panels are also available on request. Thanks to their high power density and compact design, the units are suitable for both mobile applications and fixed installations. Suitable setups as well as a Linear mode are available for all loudspeaker systems. The integrated digital delay can be configured separately for each channel and allows user-specific settings of up to 10 seconds or 3440 m. The two 16-band equalizers also operate independently on a channel-by-channel basis. They offer parametric filters as well as notch, shelving and asymmetrical filter functions. Operation is via a TFT color display with touch function, which provides quick access to the menu structure and visual information. In addition, a rotary encoder is available on the front for data entry. The front panel, angled upwards, improves readability and facilitates operation. Since each input is assigned its own amplifier output, this results in versatile applications, for example for monitor, frontfill or effect channels. The integrated LoadMatch function compensates for the electrical properties of the loudspeaker cable without the need for a separate sense line. This keeps audio reproduction precise up to 20 kHz; the tonal balance is maintained even with cable lengths of up to 70 m. The amplifier uses Class-D power amplifiers and a switched-mode power supply with active power factor correction (PFC). Operation is possible at mains voltages of 100 V, 120 V, 200 V and 230 V at 50–60 Hz. The active PFC reduces non-linear current consumption and simultaneously compensates for reactive power. NL4 connectors are provided for the outputs. An additional centrally located NL8 output provides the signals of all four amplifier channels. Via RJ45 sockets and etherCON connectors, the unit can be integrated into a remote network via CAN bus or via OCA over Ethernet. For further information on the additional functions, please contact your sales partner directly. A viewing and function test are possible at our premises by prior arrangement.
