Ashdown Klystron 500 Evo III 3 Head

<p><strong>Ashdown Klystron 500 Evo III Head</strong></p> <p>The 575-Watt Klystron 500 head features a single input is switchable for passive and active instruments with a blend of solid state and dual triode tube preamps stages. Three straightforward rotary tone controls provide 20dB of cut and boost at 60Hz, 660Hz and 5kHz, and are supplemented by two pairs of additional sliders giving 15dB cut and boost at 180Hz, 340Hz, 1.3kHz and 2.6kHz. A built-in dual band compressor acts separately on the high and low frequency components of the signal to provide precise control, while the on-board sub-harmonic generator turns the Classics into powerhouses of tone.</p> <p>The inclusion of a 4-way footswitch as standard makes Ashdown Classic amongst the most versatile live performance bass amps in the business, providing control over the compressor, sub-harmonic generator, tube grind and EQ pre-shape.</p> <p><strong>Specifications:</strong></p> <p><strong>Power Output (RMS) :&nbsp;</strong>575W</p> <p><strong>Frequency Response :&nbsp;</strong>-3dB at 17Hz and 30kHz</p> <p><strong>Speaker Outputs :&nbsp;</strong>Minimum impedance 4 Ohms</p> <p><strong>High Instrument Input :&nbsp;</strong>Impedance 3.9m Ohms, input range 150mV - 20V p-p</p> <p><strong>Low Instrument Input :&nbsp;</strong>Impedance 10k Ohms, input range 300mV - 40V p-p</p> <p><strong>Line Input :&nbsp;</strong>Impedance 22k Ohms, input level 0dBu nominal</p> <p><strong>Line Output :&nbsp;</strong>Impedance 10k Ohms, level 0dBu nominal</p> <p><strong>DI Output :&nbsp;</strong>600 ohms balanced, level -20dBu nominal</p> <p><strong>Tuner Output :&nbsp;</strong>Impedance 1k Ohms, level 0dBu nominal</p> <p><strong>EQ :</strong></p> <p>&bull;&nbsp;Bass +/-15dB @ 45Hz</p> <p>&bull;&nbsp;Middle +/-15dB @ 660Hz</p> <p>&bull;&nbsp;Treble +/-15dB @ 7kHz shelving</p> <p>&bull;&nbsp;Slider 1 +/-15dB @ 110Hz</p> <p>&bull;&nbsp;Slider 2 +/-15dB @ 340Hz</p> <p>&bull;&nbsp;Slider 3 +/-15dB @ 1.3kHz</p> <p>&bull;&nbsp;Slider 4 +/-15dB @ 2.6kHz</p> <p>&bull;&nbsp;Shape (Push Flat) +8dB @ 50Hz &amp; 4kHz, -8dB @ 400Hz, filter slope - 6dB/octave</p> <p><strong>Effects Send :&nbsp;</strong><span style="font-size:13px; line-height:1.6em">Impedance 22k Ohms, level 0dBu nominal</span></p> <p><strong>Effects Return :&nbsp;</strong><span style="font-size:13px; line-height:1.6em">Impedance 22k Ohms, input level 0dBu nominal</span></p> <p><strong>H x W x D (mm) :&nbsp;</strong><span style="font-size:13px; line-height:1.6em">310 x 470 x 240</span></p> <p><strong>Weight (kg) :&nbsp;</strong><span style="font-size:13px; line-height:1.6em">16</span></p>
