This may be the top concern among owners of older model SWR amplifiers. Although many users consider the "pop"—a transient heard at power-up—to be disconcerting, it is normal and will not damage your loudspeakers.
If you wish to avoid hearing the power-on transient, the following actions may be taken:
|•||For amplifiers with a speaker on/off switch, set the speaker switch to the "Off" position, power on the amplifier, then set the speaker switch to the "On" position.|
|•||For modular amplifiers without a speaker on/off switch, connect your speaker cable to the amplifier's speaker outputs after power up if you choose. It's important, however, to make sure that you aren't playing through the unit and that no signal is present when you make the connection.|
