Yamaha YHT 23 Home theater system

This Versatile Instant Home Theater Provides Dolby Digital and DTS Decoding and Yamaha's Tri-Field Cinema DSP and Hi-Fi DSP. The YHT-23 includes Yamaha's five-piece NS-AP327 speaker ensemble, a YST-SW45 subwoofer, plus Yamaha's HTR-5240 home theater receiver which delivers Dolby Digital 5.1, DTS decoding, and Yamaha's Digital Sound Field Processing. The HTR-5240 is a 5-channel receiver providing Dolby Digital and DTS 5.1 channel decoding, and Yamaha's Tri-Field Cinema DSP and Digital Sound Field Processing. Dolby Digital and DTS deliver discrete surround enjoyment on DVDs and laserdiscs - DTS offers discrete 5.1 channel surround on music CDs, too. Yamaha's proprietary surround processing technologies add depth and excitement to all kinds of audio and video programs. High quality performance today and ready for tomorrow. The HTR-5240 can easily accept the decoded output from any 5.1 channel surround system, whether it's MPEG-2, the new DVD Audio, or a system not yet developed. Discrete power transistors rather than IC chips are used in the amplifier section to provide the cleanest sound possible. The amp delivers 70 watts to each of its five channels. Yamaha's exclusive Digital Sound Field Processing for music recreates the acoustic personalities of actual concert halls and other venues. Cinema DSP multiplies the effects of Dolby Pro Logic and Yamaha DSP to provide the best possible Pro Logic movie theater recreation in your home. Tri-Field Processing DSP does the same for Dolby Digital and DTS. The HTR-5240's surround modes include 20 movie and entertainment modes and three modes specifically designed for music. The HTR-5240 also provides ways to customize many of these sound field settings for your particular room. Specific aspects of a sound field, such as center delay time, speaker size, and others can be adjusted, displayed on the front panel and set so they're always there in a given mode. The low bass YHT-23 system is provided by the Yamaha YST-SW45 Active Servo Technology subwoofer. It features an 8" driver and 70 watt amplifier to deliver the sonic punch needed for home theater. It is magnetically shielded, so it can be placed near a TV without degrading the picture. A volume control and 50 to 150 Hz continuously variable high-cut filter allow for seamless transitions from subwoofer to full-range speakers. All speakers included in the YHT-23 feature magnetic shielding, so they can be placed near a TV or monitor and cause no picture degradation.
