T+A Pulsar CD 1240R
The CD 1240 R offers even more sophisticated features than the CD 1230 R. The bass
range is assigned to multi-bit converters for their outstanding sonic qualities, whilst the
treble range is assigned to superior Sigma/Delta converters, now boasting 384 kHz / 24-bit
resolution. It is also equipped with a freely programmable signal processor (DSP) which
provides the basis for five different switchable oversampling filters (see CD 1230 R). As
standard it features one additional high-quality digital co-ax output, sophisticated mains
power supplies with separate high-performance transformers for the digital and analogue
sections, and additional copper shielding. It is difficult to believe, but the CD 1240 R sounds
even better than its renowned predecessor, the CD 1220 R.
