External Speakers/TK-980

[jsperandeo]

Hello everyone,

I am hoping someone here can help me in heading in the right direction for a project that I have. The police department I work for is moving to a new building and I would like to hook up our current PD radio (TK-980) to multiple external speakers placed in different offices and the locker rooms.

What would be the correct way to do this?

Thanks,

J.Sperandeo

You will need to use a PA system, too many speakers on the radio will drop the impedance and not sound right or pop the audio amp in the radio.

@kd4efm,

Thanks for the quick reply. Is there a PA system compatible you would recommend?

Lol, radio shack, if they are still around , just need something to take 4 ohm in and pass it out on say 6 - 8 speakers. Don't need anything fancy. Just a simple PA system.

Alright, I will start looking into it. Thanks for your help.

You would look for a fixed audio out of your radio, NOT speaker, and that would be line level. That feeds to the building PA amplifier on a Line input.

You'll need a KCT-19 accessory cable for this radio. That will give you the pinouts you need to get a low level audio output that can be used for feeding a line level input on an amplifier.
Specifically, Pins 4 & 6 on that connector are what you'll need.

Alternatively, you can give one of these a try: STP-1 ‐ Universal Audio Attenuator - 2 channel If I recall correctly, those will handle the low level external speaker output off the 1/8" jack on the back of the radio and let you connect to the line level input of the amplifier.

The same company has some nice small amplifiers for this sort of application. http://www.rdlnet.com/subcategory_products.php?cat=4&subcat=11
