hello agian i have a problem with the music on hold on a mics. the background music is ok but the music on hold is barely audiable. i put on the tone sender and it is low vol also. the system is programed for moh. is there a way to encrease the volume. the radio is up all the way. thank, dave

What out put are you using on the radio, speaker, headphone/earphone? (headphone/earphone port will sound better)

What are you using to connect from the radio to the 66 block?
Tip: When connecting to a radio or message on hold device I used to plug the cord into the audio out put needed and cut the other end off and terminate to the 66 block, there was a few times the music on hold should have sounded better. I had a old timer tell me to splice the audio cable to cross connect wire and terminate the cross connect to the 66 block. This did improve the sound quality.

yes im using the earphone port and the plug wire is ur spliced to jumper cable that is terminated on the 66 bolck. seems to sound ok when i put it in but now it very faint. it is a 15.00 radio. bgm seems ok.

You need a sound source that supplies 600-ohm impedance. The earphone port is not compatible. A proper source can come from any ordinary home type tuner, one with RCA style connections. This is a common problem when people try to use the wrong equipment.

I've seen this problem with tape fed MOH devices when they use the 8-ohm port instead of the 600-ohm port. Some portable CD players also have a Line port, which is the correct one to use.

Good Luck.

i didnt know that. thanks you for the info. have a good weekend, dave

If you have an 8 or 16 ohm output, get an 8 ohm to 1000 ohm audio transformer at radio shack.

The 1000 end connects to the 66 block and it is close enough to 600 that it works fine.

Also, use a real cord that you bean to punch down wire. If you cut off the end of a very thin earphone wire you may not have enough volume coming out. For about a dollar or two you can get a more substantial cord at Radio Shack.
