Beautifully racked pair of Langevin AM4A channel strips in custom rack chassis. Fully functional and in excellent condition. These were racked by Rob Harvey at World Pro Audio in Los Angeles in 2017. They have been in my smoke free home studio ever since. Added controls are as follows:
*+48 phantom power
*Phase rev
*Output pad (to allow running output transformer hot in it’s sweetspot but sending signal out of the chassis at +4db studio level)
*Load (output transformer load resistor…usually left on for best sound, but can be turned off when feeding vintage gear with 600 ohm input impedeance)
We searched high and low to find the appropriate sockets to allow these channels to be attached the same way they would be inside the console. This also allows you to easily remove the channel strips individually if you should ever need to mod or repair them.
