PROEL continues in support of its professional customers by presenting the successor of DSO26, the new DSO480. With 4 inputs and 8 outputs, the new audio management system, offers advanced signal processing, raising the performance and equipping of extra features never before available. 4 inputs and 8 outputs native processing now runs at 96 kHz resulting in wider bandwidth (over 30 kHz). Flexible routing matrix in addition to standard fixed configurations such as 4 x 2 way, any output may be fed from any input or the sum of inputs. Edit buttons show routing instantly when pressed. 9 full bandwidth parametric bands available on every output, all switchable in high and low shelving responses. 8 bands of fully parametric EQ on each input channel. crossover filters on each output now offer 48 dB/Octave responses. New higher order crossover responses in the style of NTM or Hardman filters, with crossover responses above 72 dB/Octave. Extended EQ Pack® - in addition to the standard EQ responses (PEQ/Shelving) EQ band may be changed to offer a variety of responses, from notch filters and bandpass filter, to phase (all pass) filters and elliptical and resonant filters. New additional D-Max limiter with look-ahead processing allows absolute loudspeaker systems protection. Delay memory allows for up to 650 mS from any input to any output, extra fine delay resolution on outputs in 30 nS (0.1 mm). Extended memory capacity user memories now extended to a maximum of 255. Improved converters dynamic range up to 116 dB, lower noise and improved distortion performance. AESEBU digital input interface accepts AES sample rates from 32 kHz up to 192 kHz via a sample rate converter. ALL functions are available though the front panel interface. Bigger 2 x 24 character display and new back-lit low profile ergonomic buttons.
