Condition: Lightly used and works great! The Yamaha CDX-1100 is the first player to achieve the performance of 18-bit digital decoding from a 16-bit digital-to-analog (d/a) converter.

In addition, it provides almost every operating convenience currently available in a CD player. The CDX-1100 uses 18-bit quadruple-oversampling digital filters for each channel. The 176.4-kHz sampling rate of the filters greatly reduces noise in and just above the audio range compared with nonoversampling, 44.1-kHz filters. Since the spurious products and noise created by the digital sampling process are far above the 20-kHz upper frequency limit of the CD system, they can be removed by a digital filter, in conjunction with a fifth-order active analog filter, that has a relatively gradual slope and a high cutoff frequency.

These characteristics help preserve a flat response and produce less phase shift and ripple within the audio range. Compared with 44.1-kHz sampling, quadruple oversampling gives a fourfold improvement in time-axis resolution, although this is normally beneficial only at the higher program levels. Yamaha's 18-bit filters extend this improvement to the low-level portions of the program, where they also provide a fourfold improvement in amplitude resolution and correspondingly lower distortion. The peak levels on a digital disc rarely reach the two highest, or most significant, bits of a 16-bit system, so the full capability even of 16-bit d/a conversion is needed relatively infrequently.

Many CD players, in fact, use 14-bit decoders without a significant loss of quality. Nevertheless, distortion increases rapidly as the program level decreases, and it is concentrated in the less significant bits of the digitally encoded signal. In fact, a pure sine-wave signal represented by the least significant bit is actually decoded into a square wave with a very high percentage of harmonic distortion, although it is not likely to be audible as such because of its very low level and masking by the other program material. Digital converter: 2 x PCM56P-K, 18 bit. Frequency response: 1Hz to 20kHz.

Signal to Noise Ratio: 115dB. Total harmonic distortion: 0.002%. Dimensions: 435 x 121.5 x 416mm.
