No darn pre-amp outputs on the XR25 model......arrrrg!
Since the XR45 model has preouts on the rear...would it be possible to add my own to my XR25, Im assuming its just a soldered add on or a clip in. I want to run my NAD amp for the front speakers, If I had more money Id just buy a different receiver but I'm really happy with this one so far.
Just curious if it is possible any help would be great.

Re: No darn pre-amp outputs on the XR25...
Different circuit boards are involved here, and what you propose would be cost-prohibitive in that you would have to come up with a 45 board, or rework the old board(very tedious!). Take the plunge and stay the course on factory built items in this case...accordianman

This unit has main in, preout jacks. When you say the amp works, are you referring to the amp turning on? There will be no sound out of the amps, if there is no preout. Are you aware that there needs to be jumpers between the main in and preout jacks? If you don't have the jumpers, no problem; just use a stereo patch cable between the jacks above.
If you are using a pre out to a sub woofer, you need to make sure that the sub has it's own power amp or it will not work. You also need to go into the user menu and tell the amp that you are using a powered sub. Otherwise it will not turn on the pre amp output
According to the specs for the xo 1945- the output is; 50W x 4 Max Power Output , and I do not see a pre amp output listed. So I think to connect subs, you will need a separate AMP.
The way this works; the rear speaker wires from the xo 1945 hook into the Add-on amp, for example a 4 channel amp. In a 4 channel amp, the rear speakers come off two of the channels of the add-on, and the subs come off the other two channels. There is also the option of bridging two channels for more output power to ONE sub.
You did not mention what size sub(s) you were thinking of adding, but keep in mind that the ox 1945 puts 50 watts MAX per channel. So, if you add two 12" subs and a 1500 watt amp to drive them, your total sound is going to be very uneven.
If you go on line and look up auto audio or amps, you'll get a good idea of all the Sub and amp options that are available.... Hope this helps.
Hi, just turn up the gain, though the max voltage may be higher, it does not mean the audible output is higher, alpine decks subwoofer control is an attenuator, so at max it will be the same level as front n rear, on min it is -15db... you will probably find the kenwood is +/- 7db so it has a gain boost...
just crank up the amp gains, problem sorted...
I've got the same model and the pre out transistor needs to be replaced,
sometimes you can get it to work by unplugging the reciever and the pre out
then plug in the reciever and plug the pre out in a couple of times or so untill it comes on
or unplug the amp from the wall then plug in the pre out , turn on the reciever wait for sounds to come on then plug in the amp.
if that don't do it the pre out transistor needs to be replaced
1 Use MULTI-CONTROL to select SW CONTROL. 2 Press MULTI-CONTROL to display the setting mode. # Press BACK to return to the previous display. 3 Press MULTI-CONTROL to select the segment you wish to set. Press MULTI-CONTROL repeatedly to switch the segment in the following order: REAR SP (rear speaker setting)—PREOUT (RCA output setting) 4 Use MULTI-CONTROL to select the desired setting. Turn to change the setting. When REAR SP (rear speaker setting) is selected. REAR SP:SUB W(subwoofer)—REAR SP:FULL (full-range speaker) When PREOUT (RCA output setting) is selected. PREOUT:SUB W (subwoofer)—PREOUT:REAR (full-range speaker) # When no subwoofer is connected to the rear output, select REAR SP:FULL.
You need to match your amp's input voltage (the gain) to the output voltage supplied via your deck's preouts. Turn you radio up to normal listening level, and turn the amp's gain until you induce audible distortion then back it off slightly. Set the bass boost and crossovers to on and type (highpass for front/rear full range or lowpass for subs).
Yes you can use the speaker output in conjuction with the rca pre-outs...but depending on the wattage of the amp, there may be a big difference between the loudness of the front speakers over the rear speakers. If you have a 4 channel amp you can put the rear speakers on the amp also and lower the input gain for the rear speaker. Or if you have a 2 channel amp, you could use a passive crossover to filter out some of the bass to the rear speakers since they are smaller, this would help prevent over-driving them...as it is normally too much bass that distorts and blows a speaker. I'm not sure what you are asking about the hi-rear preouts vs the mid front pre-outs. If you decide to use the amp for the fronts you should be able to connect the amp from the front preouts of the deck. Hope this helps.
OK, From what I am understanding is that you both are trying to uilize a digital audio source (HDMI cables are digital audio only) and hence this is the problem. You can only use an analog audio source (connection) to utilize the audio output to zone 2. A simple soultion is to use the analog audio in conjuction with the digital. Connect the digital (HDMI, Optical, Coax) to the main zone and the left and right audios to zone 2.
