Adding external speaker to XTL 2500 / HLN6042A setup

[ganu76]

At our shop we keep an XTL 2500 and HLN6042A base stationed inside one of our offices, but we'd like to run an external speaker out into our bays where we work. There is a lot about impedance, etc that I don't know about when it comes to audio and speakers. The plan is to tie into the existing plug connecting the radio and the base together.

Our bays aren't terribly noisy, as we do 99% of our work either in our offices or outside and away from the shop, but we would like the ability to hear radio traffic in all area inside.

The 2 bays have a shared half wall, and each bay is 30' x 45'. Would love to run a single speaker to this half wall so as to cover a 60' x 45' area. This run would likely take 100' of wire from base to new external speaker. (I'm ok with splicing speaker wire if need be/possible.)

Thoughts? What all do I need to consider?



Thanks in advance.

Pin 21 on the rear accessory connector on the mid power radio is the place to get the RX audio. It is filtered and follows the squelch of the channel settings. It does not vary with the control head volume control setting. The same goes for pin 6 on the DB25 connector on the high power radio. Add a blocking capacitor in line with the Accy connector on pin 21. You'll need a ground lead from pin 1 also.

And route the filtered audio to your PA system amp.
