Playing the modular through my home stereo

[Tim Ressel]

Dear --M,

Keep in mind the following is "worse-case" and may not apply depending on your
setup and style.

There are several concerns when plumbing a synth straight into a amp/speaker
combo. Certainly limiting the amplitude will prevent any "pops" from taking out
your drivers. Transients, such as when patch cords are placed, can cause a large
impulse to travel through your amp and maybe destroy the tweeter.

There is another hazzard. If you push significant amounts of high frequency
energy into your stereo, say an inadvertant 20KHz square wave at 20Vpp, all of
those ultrasonic harmonics are going to go straight into the tweeter, which may
or may not survive.

If I were putting my synth into my ultra-expensive Klipsch cornerhorns (brag,
brag), I would employ a limiter (SSM2166 works spiffy for this), and some HF
lowpass filtering, say a simple RC corner at 20k.

But then, my middle name is overkill...

    Hey all I've been playing my modular through my home stereo. Is this
bad? It sounds ok but sometimes I worry that I may fry my stereo? A
friend suggested a limiter? What do you guys think?
    I like to use the stereo its very convient I can record from etc.
