Question about Audio Players & Recorders

Open Question

I have a dukane PA system for a detention center. The model number for the Audio/control Panel is PN 1A957. The problem is that I can't get the speakers to act as microphones like they are supposed to. I think there is a voltage issue. The system has a control panel and 4 switch/call banks (with 25 toggle switches per bank). I can receive an alert and talk back to the calling party but I can't hear them. Sometimes the receive audio will work but most of the time it doesn't. I measured the voltage going into the call banks and there is -12 VDC. I can't find any documentation or manuals on this product because of it's age. I think the problem is the wiring considering how much work has been done on the site. So I need to know how the system works and what is expected to happen when calls are made.

Hi, I had the same problem, MiMusic wouldn`t even recognise there was a disk connected although I could see it in My Computer.Found the answer on internet.
Attach it to your p.c. Then go to My Computer and highlight it. Right Click it and a box will appear . Go to FORMAT and format it. Another box will appear and ask if you really want to do it as data will be lost. Answer YES. Then format it. Disconnect from your p.c. Turn it on and you will be able to access the menu facility. Follow the instructions and goto CREATE LIB, BEFORE you put any music on to the thing.
I found it created library as soon as I disconnected it. BACK UP anything you have on it first as it will be wiped. It is working perfectly now and MiMusic is too. Yippee. Pat.

SOURCE: Rio Riot

Have a try with this one:

http://www.digitalnetworksna.com/support/rio/downloads/rmm/Rio_Software_Ver260.exe

Although not officially available (or supported by DNNA) for the Riot, it happens to function with the Riot as well as newer players. Potentially later updates to RMM might break support with the older players.

SOURCE: mp player says file system error will not do anything

Try treating your MP3 player just like it was a flash drive (which it really is, sorta). Hook up the USB, "explore" it, and then "format" the drive ("k:/phillips" in my case).

Aai have the following AKAI Audio Stereo System and no Idea how to connect them. Please help Akai Model AP-D210 turntable Akai model CS-F14 Stereo cassette deck Akai model AT-K110 Fm Am Tuner Akai...


In general, outs to ins.

If nothing else, get the manuals for the preamp and the EQ. You'll probably have to pay for them.

Google it.

Akai PR-A04 preamplifier << This is the control center and where everything comes together.

Akai AP-D210 turntable (ONLY to jacks that say "PHONO"
Akai EA-G40 Stereo Graphic Equalizer (in the Tape 1 Out/In set)
Akai CS-F14 Stereo cassette deck (in the Tape Out/In set of the EQUALIZER) *
Akai AT-K110 Fm Am Tuner (to the Tuner inputs)
Akai DT-100 Audio Tuner (to the Aux inputs)
Akai PA-W04 Amplfier (to the amp outputs)

* This will allow you to Equalize the Tape on the Record or the Playback side.

Read some audio magazines or websites. Get to understand Tape Monitor Loops.

Don't use excessive EQ.

How do you replace a battery in an Anchor Liberty 4500 PA system?


Here is the link to the manual if you don't have one:http://www.google.com/search?hl=en&q=Anchor+Liberty+4500+PA+system+battery+power+replacement&btnG=Search&aq=f&oq=&aqi= It appears as if you have to remove the entire control panel to replace the two batteries. You probably have to use exact replacements. THe link to the company is in the manual and they can probably give you more information. Hope this helps.

How can I connect my P.A. system to pur phone system? cheaply easy Phone is NEAX PBX P.A. system is basic pre-amp output (analog)


This is very tricky unless your phone system has an analog audio line input provision. It's almost impossible to introduce external audio ( from your P.A. system ) into the phone system when a phone is on hold unless the PBX system has an external audio line input. If it does, all you need is a standard 600 ohm to 600 ohm audio transformer where you connect your P.A. systems preamp signal out to one side of the transformer and the other side of the transformer to your PBX systems external audio ON-HOLD line input.

Sears Kenmore Elite Oven 790.99123405 Caught Fire!!!


The PF indicates a power failure.
The range experienced a loss of electrical power.
This code is usually cleared by pressing the CLEAR/OFF button.
If you continue to get this code, you may need to unplug the range and check the wiring connections of the power cord on the back of the range.

Sound Quality


I also have a Samsung 46 inch HDTV and have the same problem. I reported it to Samsung. They sent out a repair man who replaced the entire audio system... I did not help at all. Sound quality still very bad. Hard to understand audio voice on most movies. Is there a solution short of installing an additional home theatre system?

Adapting a 4 channel pa system to plug into a marantz cd310 digital recorder


What is the new Pa System Brand and Model. I am almost certain that every PA System sold has a stereo or mono out put and yes there are adapters to go from mono to left and right (stereo ) on your CD310 recorder. So, the simple answer is to look at the manual or even the back of the mixer to fins out where the audio is coming out of the mixer. The mixer on the pa system will mix the sources together for you. So, you might not need much of anything but a cord to get the audio to your recorder. You can send me the model number and I can give you the exact cord you need or you can take it to a near by store that sells audio pa systems and show them what you have and what you are trying to do and they will sell you a cord that will solve your issue.
