Ext Hold Music Quality

[Neillsun]

I have an mp3 player hooked up to play my hold music on repeat (yes we do own the rights to the music).

The sound quality is a bit shoddy. Is there something I can do - set levels/hardware filter/etc - to try improve the quality? One thing I have noticed Is I have to crank the volume of the mp3 player to the max, so I am guessing that is half my problem... and the impedances don't match.

Anyone solve this?

Thanks,
N.

you could try a WMT1A matching transformer, works for paging so I guess it would do the trick for MoH as well. That is if the impedance discrepancy is your problem.

Thanks. I'll give that a try.

Remember that if you're testing from your cell phone, it will always sound crappy. *34 or *341# from a system telset (depending on software version) is a better method to check quality.However, if you have an impedance mis-match, poor quality is inevitable.

I wasn't aware of the cell phone testing quality, but it is poor using *34.

I'll try the impedance transformer. I don't see the WMT1a being too available in the UK, but found another Audix T50K Impendance matching transformer - Low output(100-600 Ohm) to Hi-Z 50K inp.

I might have another one floating around with some audio codecs we have.

Music with a high range of notes sounds pretty crappy on hold no matter what. Following the strict guidelines outlined by Avaya for their onboard MoH seems to provide better sound. Which is the mono, 8bit less than 64k approach.

I have converted the music to Avaya's standard. Even tried some noise reduction filtering. Bit of help. If this doesn't work then i'll just leave as is.

Thanks.

I rarely have issues when using a standard 600 ohm line level device. Something made to play MOH will give you much fewer issues in the long run.
