Audio Research LS26 preamp The new LS26 physically resembles a downsized REF3, with a smaller vacuum-fluorescent display flanked by knobs for Volume and Input. Under the display are six soft touch switches controlling Power, Mono/Stereo, BAL/SE, Processor (pass-through), Monitor, and Mute. The LS26 maintains all of the LS25's inputs, outputs, controls and functionality, and adds phase inversion via the remote control. The display shows the volume, input, balance (via L-R line graph), and operating status (including BAL/SE, Hi/Med/Low Gain, Mute, Stereo/Mono, Invert, and Tube Hours). There are eight levels of illumination for the display, plus off.
