Adjust the Volume of a Pair of Speakers from a Convenient Wall Mounted Knob
The Niles VCS100R Stereo Volume Control with Selectable Impedance Magnification is a wall mount, stereo speaker volume control. It connects between the speaker-level output of an amplifier, speaker selector, or distribution hub and a pair of speakers. A perfect application for the VCS 100 is adjusting the volume of remotely located speakers. The VCS 100 adjusts the volume of speakers connected to it by attenuating the amplifier signal. To assure minimal dissipation of internal power with virtually no power wasted as heat, Niles volume controls use autoformers instead of L-pads as the volume-controlling element. The VCS 100 is an impedance-magnifying (IM) volume control. Unlike other brands, it has additional autoformer windings that magnify the impedance of connected speakers, while allowing all 12 steps to adjust the volume of the sound. Switches on the PC board select these windings. With the volume control providing impedance protection for your amplifier, you can create systems with no additional impedance-matching devices between the volume control and the amplifier.
This product is also available in bone, black, brownand white, each sold separately.
Distribute a Single Audio/Video Source to Three Destinations
The Niles AVDA-3 Source Level Stereo Audio/Video Distribution Amplifier allows you to take a signal from an audio/video component and send it out to one, two, or three different TVs, monitors, or receivers. Unlike y-splitters which can cause signal loss, this high-quality distribution amplifier splits the signal without any signal degradation. The Niles AVDA-3 can be either mounted on a wall using screws or placed on shelf using the included adhesive rubber feet.
SONY: Remarkable Noise Reduction and Pristine Audio Quality
The MDR-NC300D headphones are equipped with a feed-forward noise canceling (NC) mechanism which cancels noise near the eardrum by estimating what kind of noise it will be when it reaches the eardrum based on the ambient noise collected by the noise detection microphone, and generating an inverted sound waveform. The noise canceling performance greatly depends on the efficiency and precision of the NC circuit to generate the noise canceling waveform. The NC circuit uses the newly developed integrated DNC processor. Compared with the previous analog type, it boasts excellent noise canceling performance and outstanding sound quality.
