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. Like the REF3, inputs are direct access and there are discrete codes for power on/off, processor, and other functions, so it will be easy to integrate the LS26 with system controllers from companies like AMX or Crestron. The rear of the LS26 includes a 12V trigger and a 15A IEC connector. All inputs and outputs are both SE and XLR.
OVERVIEW
Good condition traded-in Audio Research LS26 Linestage in Black.
Unit come in its original box and packaging with manual, power cord and remote.
The unit is rated a 7 out of 10 due to wear consistent with use and a mark near the back of the unit on the right side (see pics).< br>
