Tty mode speaker problem

What's changed? Has the computer been moved? Cat or dog been around the connections? Kids?

What surround mode is it in?

Well... you probably won't like this, but here is some info: In bridged mode, a different Speakon to speaker cable is required from only the B... it is wired differently and you can only use one of the plugs. The speaker or speaker system CANNOT be less than 8 ohms in bridged mode... this precludes using speakers in parallel or multiple speakers that are less than 16 ohm impedance... such speakers are NOT commonly available as most are either 4 or 8 ohm. There is a slide switch for bridged mode on the face of the mixer. Next thing you won't like... The 1200 Watts specification is PEAK power, NOT RMS... You can get 400 watts RMS per side USING 4 ohm speakers. If you use 8 ohm speakers, each of those will get 200 watts. I use this mixer myself and ALSO repair them. The voltage swing at the outputs is about +/-60 volts MAX (peak). This is about 40 volts RMS by the time the circuit LOSSES are taken into account. Across a 4 ohm speaker you get 10 amps times the 40 volts or 400 watts. Across an 8 ohm you get 5 amps or 200 watts. The voltage rails in the switching amp are +/-70 volts DC so these are reasonable values. Bridged mode just uses both sides of the amp driven in opposite directions for higher voltage out BUT you have to use no less than a single 8 ohm speaker so there is NO advantage to bridged mode power wise. IF YOU NEED more power, use extra speakers from an additonal amp driven by the 1/4 TRS mains output jacks OR use additonal POWERED speakers driven from the same jacks. Please read my tip about the hazard regarding the SLEEVE of the cahnnel A cable when using Speakon to 1/4 plug cables being the HOT and the tip being the cold for channel A. Ground the sleeve accidentally and goodbye channel A amp...

On the front display of the unit, you should have indicator icons that light up if a speaker is being used. Are there only 3 speakers lite up, or are there 5? As a quick check, make sure your speaker connections are secure, and then make sure your surround mode is set to a 5 channel surround mode. 5 channel Stereo is a good one to test with. Also, you can hit the "test" button to see if the speakers are connected and working, it will give a test signal out of each speaker independently. Let me know what you find, and I can answer more.

I had the same deal. But I was able to solve the issue. Go to your setting and tools and go to phone setting and check your TTY modes make sure that your phone is check under TTY-Hearing if not that's your problem ..make sure you check it and save it than turn off your phone and wait 5 minutes than turn it back on.. and you should be set. Ready to use

its probably the mute button on the keybard, hitting it again will unmute it. also check in the taskbar, bottom right corner of screen, click on speaker icon and uncheck the mute button.

Your best bet would be to visit a full line phone store.
Look for a clear-phone on display. You would see all the stuff: diodes, sensors, speakers, tiny-bulbs etc. All these items are similar to what's inside a TTY.

easiest way to solve this problem. go to call settings and TTY mode. and switch it to TTY + talk ... if that doesnt work then fiddle around with the other TTY settings untill it does. this disables the earpiece

No ringer volume or speaker phone

Try disabeling TTY unless you need it it (it is a hearing impaired function). To disable do the following: In idle mode press the Menu soft key to access menu mode,
Select Settings and highlight Phone Settings,
Press the Select soft key or the Cingular key,
pres the 5 key and highlight the Disable selection,
Key in the password: 4889,
Press the OK soft key
For additional technical support call 888-987-4357

you are in stereo mode which only uses the two front speakers, hit the surround sound button remote or hit the mode button and cycle through until you get to the Dolby II setting
