At 7.4kg (16.3lbs), the LA30D is compact yet packed for performance. 30 watts real RMS linear output power is allied with pair of 6.5 drivers. These custom-designed speakers house a unique dual-cone design which deliver full, natural acoustic sound-reproduction with plenty of high-end sparkle. Two independent input channels both offer the choice of balanced XLR or unbalanced jack inputs and both can have Reverb assigned to them as required. This flexibility allows for connection of a mic and instrument, two different acoustic instruments or even a blend of separate mic and pickup connections from the same instrument. Plus, with an additional Aux in connection for backing tracks, the LA30D is ideal for acoustic guitar + vocal performances. The Instrument channel features useful tone-shaping via a three-band EQ plus a Shape control for instant single button optimization for electro-acoustic guitar sounds. Variable Chorus and/or Reverb is on hand for further sound enhancement without the need for external effects units. The Chorus is visibly engaged with a green LED light which will then pulse giving an indication of the LFO (low frequency oscillator) rate. This rate can then also be adjusted by simply holding down the Chorus switch and turning the Reverb control pot. On letting go of the Chorus switch, the rate is stored and will even be recalled at the next switch on. A simple but very effective Anti-Feedback button can be engaged to automatically scan for and then eliminate unwanted feedback. A Phase switch is also on hand to remove of destructive interference which can occur when a player is too close to the amplifier; a simple solution at the switch of a single button.
