BW POWER AMPS
B & K Components introduces four new amplifiers designed to meet all of your stereo and home theater needs. The ST2140, which is rated at 140W into each of its two channels, has enough power to drive even the most esoteric speakers to dynamic levels, while delivering excellent detail, superior soundstaging, and a truly rich sound, according to the company. The ST260 delivers a harmonically rich 60W at 8C2, with enough power to drive most speakers in "real world" sized rooms. The ST3140 is designed specifically to meet the demands of today's dynamic movie soundtracks by delivering 140W to each of its three channels. The ST140M is a mono amplifier that delivers 155W and 60A of peak-to-peak current to control low frequencies.

AUDIO TESTER
TDL Technology, Inc., announces its Model 109 for audio system testing. It incorporates a pseudo-random noise generator for white and pink noise output, a "10-sine" generator, and an arbitrary waveform generator. You can set test mode and output voltage from the front panel or by a personal computer over an RS-232 link. The EEPROM can be programmed over the RS-232 for arbitrary waveforms. Examples (included with the instrument) are a two-tone output for IM distortion measurement and tone-burst.
