Horizontal or vertical placement due to rotatable mid-high baffleThe A300 is designed as a classic 3-way reference monitor with time-aligned sound conversion by FIRTEC(TM). As with the legendary ADM20, all frequencies in the A300 are radiated so that they arrive at the sound engineers' ears simultaneously, not time-delayed. This tonal neutrality and time alignment allows the A300 to be used in all areas of professional production processes, during recording, as a mixing monitor or in mastering as a final reference. The 10-high-power bass driver, the 2-dome midrange and the dome-less 1-high driver transmit from 26 Hz upwards and offer enough reserve for any volume. The design of the amplifiers and power supply units ensures extremely low distortion. Our patented FIRTEC system filters ensure phase-linear, time-correct reproduction over the entire frequency range. The waveguides fade out the cabinet edges and linearise the frequency response in addition to the digital signal processing. The 1-tweeter ring radiator ensures low-distortion reproduction even at higher levels. Whether connected via the analogue input with 24-bit / 192 KHz AD converter or digitally from the workstation without loss, the A300 impresses with its easy integration into the studio setup. The high- and low-shelving filters, accessible from the amp side, allow for quick set-up and room adjustment, which can be refined with additional internal filters using the optionally available RC-100, if required. Three freely configurable peak EQs, as well as high and low shelving, allow the set-up to be adapted to the listening position. The monitoring volume can also be controlled directly in the monitor, so that a digital connection with full-scale level directly from the master output is guaranteed without loss. Another special feature is the transformerless connection of the 3 PWM power amplifiers with 250W RMS power each. This direct connection prevents transformer losses and leads to an extreme resolution in the time and tonal range.
