    It seems that the tuner part of the new Arcam solo is based on a new model from Arcam... Anyone has more info on this new tuner?

    • DAB coverage for both band III and L-band

    DiVA range gets new combined DAB / FM tuner

    As the first company in the world to produce a domestic Digital Radio tuner, Arcam has played a pioneering role in the rollout of DAB digital radio. The Alpha 10 DAB tuner and subsequent FMJ DT26 and DiVA DT81 digital radio receivers, all engineered and produced in the UK, have gained a reputation as some of the best in the world.
    The new DT91 builds on this foundation, using state-of-the-art technologies to deliver the very best radio quality from DAB and FM broadcasts. All-digital processing using a powerful DSP delivers crystal clear reception regardless of the broadcast method. The digital to analogue conversion and output stage designs use Arcam’s audiophile methodology and are fed from a toroidal power transformer and multiple low noise regulated dc power supplies, all mounted on a double-sided fibreglass PCB. Station selection is via presets or the large front panel knob. The 128x18 VFD display has smooth scrolling text and is easily read from any angle or in any light condition.
    In addition to its class-leading audio performance, the DT91’s connectivity and control features are also state of the art. The RS232 control input, a first for domestic DAB radios, makes the DT91 a perfect radio tuner for custom installations using Crestron or AMX style system controls. For simpler systems the unit features an IR jack input on the rear panel plus a fully featured remote handset. Outputs include two pairs of analogue RCA phono sockets plus coaxial and optical digital outputs for both DAB and FM.
    Delivery of the DT91 is due February 2005.

    UK recommended retail price (inc VAT) £449.90
