remote bass knob?

now we installed the Lanzar 1800d a couple of weeks ago...i set the gain by ear at the amp, then plugged in the remote bass control expecting it to be a gain attenuator...i find out later that that amp does put out different AC voltage readings with/without the bass knob plugged in.

:idunno:

advantages: adds sub volume control independant from other speakers when no sub controls are built into radio

drawbacks: less room for future wires in sideboards, probably mounts via screws, more time lost (mainly concerning commercial installs) If the subs 'get louder' when the remote is used, I would bet the manufacturer set the amp up that way to make the remote gain appear better than what it is, and I'm not a big fan of smoke and mirrors. It is simply a knob to turn the amp down, I have never seen one with a miniturized second amp inside the remote gain box :)

need it? only if the amp will not function without it (uncommon) or if the radio (usually factory) has no sub controls built in

as far as a difference in output in amps that function with or without it.. the difference is probably so minor as to require a multimeter to accurately detect

personally I avoid them if possible as these addons often look fairly cheap and are likely only good for the life of that amp (at my shop we try to avoid screw holes whenever possible >=P ). sometimes the system balances out well enough at both high and low volumes without the need to adjust the sub levels independantly
