Convert optical digital audio outut to connect to my rca headphones


Are your RCA headphones wired, IR, FM wireless, or do you mean they have RCA/phono plugs?
Whatever the config, you'll need a DAC,or digital-to-analog converter for a start, as the fiber-optic transmits a digital-encoded pulsed signal only, which has to be decoded back to the audio sampled voltages to re-create the original wave-shape.
The DAC must have D/A optic input.

How many Dac in 3010 yamaha receiver


What exactly do you mean by DAC (Digital-analog converter)?
As the audio core of this receiver is digital, it has an ADC for each analog input. Then it has one DAC for each analog output, so it has 13x DAC for Pre-out (11.2ch which are used also as inputs to amplified speaker outputs) + 2x DAC for stereo AV out + 2x DAC for stereo headphones.

NAD WIRELESS USB DAC 1 KILLS WIFI CONNECTION


The NAD wireless using the 2.4Ghz frequency which is also used for WIFI.

Your option would be to change the channel of your WIFI to see if you can reduce the interference.

Your best option is to use 5Ghz for your WIFI (this requires that your Wireless router and Laptop support 5Ghz).

Where is the headphone socket on a LT24M3


This is a link to the manual.http://www.haier.com/admin/en/product/upload/LT24M3-UM.pdf
On P.08 it shows the input and outputs. This television does not have a headphone jack. It has a digital audio output which is the SPDIF output.
To use headphones with the television you would need to get a digital to analog converter. Something similar to what is shown here: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=180-998
You would also need a digital audio cable (SPDIF cable). They are about $15-$30 depending on where you get it and the brand.
You would connect the SPDIF cable to the television output and the digital to analog converter box (DAC), and connect the headphones to the DAC box.

I have an analog tv (coax cable) and a new dvd (av plugs) player. How do I inexpensively connect them? i saw the solution posted about the rf modulator. I have a digital to analog tv convertor. Is this...


NO. An RF modulator and your digital-to-analog (DAC) TV converter are 2 different devices. The DAC will convert over-the-air (OTA) digital television signals from your antenna to analog NTSC format so your older analog TV can receive OTA broadcasts. The RF modulator converts base-band video (composite cable/RCA connector, or S-Video cable connector) to channel 3 or 4, so you can watch video/audio on your set. To use both the RF mod. and the DAC converter to the same TV, use an A/B switch for F-connector coax, or follow the directions for the RF modulator to make the correct connections.

Analog / Digital stations


Hello mikekahan,

OK you are not going to like this but here we go any way. First of all I need to explain how your channels are created.

When the RF signals come into the headend of the Down converters they are separated into pre channelized designations DC (Down Converter) 4 Stream 1 (DC 4-1, DC 4-2...) now once this is done the down converter signal is fed into a channel processor which takes the incoming signal from the Down Converter remodulates it and puts it on an assigned channel 4-1 could become channel 4, 4-2 could become channel 5 and so on. Once this is done you end up with your regular channel line up for analog channels, now for digital its a little different you have IRDs (Integrated Receiver Decoders) which take the off air or satellite Digital RF signals and convert them into MPEG Streams which is the fed into what is called a SEM (Motorola Architecture) Stream Encryption Module which assigns numeric designations to the MPEG streams and then converts the MPEG streams back into RF. Now at this point we have analog and digital signals what then has to happen is the the analog signals must be turned into MPEG streams to go through the system so what happens is from the channel processor the analog signal is put into a SE (Stream encryptor) Like the SE1010. This takes the analog stream and turns it into am MPEG stream and feeds it into the SEM also and the SEM assigns a numeric designation just like the digital signal and this can sometime follow the same numeric designations as was obtained from the Down Converter, So what you end up with is analog and digital signals having the 4-1, 4-2, 5-1, 5-2, ..... format. This is where other equipment comes into play These designations are then kept in a database and are matched to their proper channels by use of the DAC and RADD along with an IPG server. These allow the SEM to assign true channel designations to the converted channels, now the SEM DAC, and RADD talks to your STB, this is way the channels are correct because the SEM and the DAC/RADD are matching what is on the IPG (Interactive Program Guide). When you remove your cable box the tuner in your TV does not know how to deal with the DAC, RADD and IPG signals so it only displays the RF information which is the 4-1, 4-2, 5-1, 5-2 data.

I hope this helps,
