I've just got myself a QSC RMX2450 poweramp and I plan to use it with my Ashdown ABM300 EVO head. I've connected the Ashdown to the QSC via the "effects loop send" socket on the head to the "Channel 1 input" on the QSC. Now, this works and I get a wonderful sound, only, it seems to me that it's not exactly drying my clothes like I expected it to do. Does anyone know of a reason why I could be having problems? Is the effects send signal from the Ashdown too low? Okay, I'll try and answer my own question.. tell me if I'm right.. The output level from the Ashdown's fx send socket is -10dBu but the input on the QSC is +4dBu. Am I just gonna have to buy myself a preamp or is there a way to get more signal into the QSC? Thanks all.
