| By Charles Hansen Bicron Transformers Bicron Transformers Bicron Electronics has introduced the AA series toroidal power transformers for audio applications, ranging from 20VA to 2kVA. All transformers have dual primaries that can be connected for 120/240V AC. In addition to a large number of standard secondary winding connections, the website has a custom design calculator for specific amplifier applications. Efficiencies are in the 85%-95% range, with low losses for re duced standby power consumption. The transformers are designed and manufactured for low vibration, and minimal audible and electromagnetic noise. Various mounting, shielding, and output termination options are available. The transformers are de signed to meet all CAS, IEC, VDE, and UL standards. --- Bicron Electronics Co. 50 Barlow St. Canaan, CT 06018 www.bicronusa.com (860) 824-5125 --------------- The DSD1700 is a unique digital-to-analog converter (DAC) designed for DSD audio applications. The DSD1700 consists of a single-channel, 8-tap analog FIR filter with a double differential circuit architecture, ensuring excellent dynamic performance and high power-supply noise rejection. The DSD1700 also includes the necessary logic required to interface directly to a DSD decoder IC. The overall features and performance of the DSD1700 make it an ideal choice for high-performance Super Audio CD players and DSD studio applications. FEATURES Direct transfer of Direct Stream Digital data stream to analog output Dual Differential analog FIR filter Direct, CMOS logic interface to DSD--- decoder IC Data Clock: 2.8224MHz (64 * 44.1kHz) System Clock: 11.2896MHz (256 * 44.1kHz) 1-bit Resolution Dynamic Performance THD+N: 0.001% (typ) Dynamic Range: 110dB (typ) SNR: 110dB (typ) Frequency Response (-3dB): 100kHz Single +5V supply 27.5mW Pd (typ) 2822.4kHz sampling rate (max) The DSD1700E is available in a small 28-pin package for $9.95 US in 1000+ quantities.
