Product Q&A
My 104's aren't picking up my laptop's Bluetooth signal. My laptop hasn't given me issues with any other Bluetooth device. I keep turning them off and on but nothing is happening as far as the Bluetooth picking them up. They are brand new. Help, please.
is it possible dont HEAR the "TURN ON SOUND" every time i turn it on?
Are the 2 balanced TRS inputs Left and Right channel respectively or can one TRS input support both L/R channels?
Can I use two inputs simultaneously(not just plugged but playing simultaneously) with these speakers ?
Just bought 104-BTs when turned off from laptop they return to speakers on laptop and have to be reset everytime.
How far apart can the 2 speakers be placed?
Is this product compatible with the LSR310S subwoofer?
Just purchased your 104-BT Monitors. Is there any way to disable that annoying blast of intro noise when you first turn on the monitors? The monitors seem solid. Still getting used to the shape of the monitors.
