Product description The Palmer PMBLA is a two-channel, stereo line-level merger box with active circuitry, designed to combine two stereo line-level signals into one stereo output, with lossless mixing and signal amplification. It can be used for simultaneously connecting two mixing desks to a single PA system, such as a DJ mixer and mixing console to a studio or live venue sound system.Featuring combo sockets with XLR and 1/4" connectors, channel 1 is designed for both consumer-level equipment and professional gear with input sensitivity switchable from -10 dbV (consumer level) to +6 dBu (professional level). Channel 2 is optimized for +6 dBu professional line levels only. The inputs are galvanically isolated from one another to prevent crosstalk.Both channels feature a mute switch and a mono switch to mix the stereo signal down to mono. Rotary controls set the overall levels with a maximum input signal boost of +16 dB. Individual ground lift switches are provided for each stereo input and the output.The PMBLA is housed in a 1 RU, half-rack case and has a built-in power supply. - Key Features
