View Full Version : Sub hook up to vintage receivers
uppington 10-04-09, 09:54 AM I have my Pioneer 51 FD Bluray player hooked up to a Harmon Kardon 930 vintage receiver for CD playback via the left and right analog stereo output jacks on my Bluray player, going to the tape monitor input jacks on my receiver. I beleive there is a LFE bass signal going through as well. Does anyone know if it is possible to hook my sub up to the vintage receiver to play the bass signal. Can I hook up my tape monitor output jacks on the receiver to the left and right speaker level inputs on my sub? Does anyone know if this will work?
Thank you for your responses.
1) use an AUX input for the audio connection from BR player. No reason to use Tape Mon.
2) If your sub (hopefully) has speaker level in/out, just run speaker wire from the HK to the sub speaker inputs, then wires from the sub speaker outs to the speakers.
3) you cannot use the Tape mon.

Firstly, no, the LFE signal is not being folded into the 2-channel mixdown that your player is sending to the receiver. Players drop the LFE information. That does not mean that using the sub to augment the bass that is there in the other channels is not useful. It probably is. There is plenty of bass in the other channels. Just realize that you are not getting the LFE channel.
Secondly, unless you just don't have another input to use, what do you think using the tape monitor input will provide you that a standard input can't? If anything, with that connection scheme, you would want to use a line-level connection from the tape monitor outs to the sub's pre-in(s). Not a speaker-level connection. But with that sort of connection, you will not have any way to control the sub's volume simultaneously with the speakers, so it is pretty much useless.
As Ratman says, provided your sub has speaker-level inputs, just connect the subwoofer with a speaker-level connection form he receiver's speaker oututs. If the sub has high-passed speaker-level outputs, you can use them to connect the speakers, if high-passing the speakers is what you desire. Otherwise, if you would prefer to run the speakers full-range, you can simply connect them to the receiver's speaker-level outputs, too. In either case, you will use the sub's own variable low-pass to adjust it to the speakers' low-end output.
What is your subwoofer?

What is your subwoofer?
Hi
My sub does not have speaker level outputs, just inputs. So are you saying that I can hook my sub and my speakers to the same speaker level output terminals on my receiver?
On my receiver I have Speaker A and speaker B terminals controlled by pushbutton switches. Can I run my speakers off the Speaker A terminals and my sub off the Speaker B terminals with both pushbuttons being pushed in at the same time?
I have a Paradigm PDR 10 sub.
Do you have a link to the user manual to the PDR-10?
If the sub only has speaker level inputs and no outputs, that's kind of strange.
If you have limited input/output options on the sub and a "relic" for a stereo receiver, you may want to consider upgrading. ;)

Can I run my speakers off the Speaker A terminals and my sub off the Speaker B terminals with both pushbuttons being pushed in at the same time?Well, this sort of depends upon whether the A and B speaker outputs are in series or in parallel. If they are in parallel, as most receivers' outputs are nowadays, it should be fine. If they are in series, as they sometimes were on older receivers, there MIGHT be some concerns in doing that. Can you connect your speakers to the B terminals only and operate them properly without using the A button at all? If so, your A and B outputs are simply parallel outputs.
sivadselim 10-04-09, 06:05 PM If the sub only has speaker level inputs and no outputs, that's kind of strange.Not really.

Uppington, you can use a sub with your speakers running full-range to augment the lower-end but, again, you are NOT getting the LFE channel with a 2-channel analog connection from your player. Realize, though, that very rarely will something be encoded solely in the LFE channel. There is almost always overlapping material encoded in the other channels (particularly the front), often reaching down quite low, so, with a 2-channel system, reproducing the LFE channel is not absolutely necessary to get a decent experience. But, if reproducing the LFE channel is important to you then, as Ratman said, you may want to consider a new receiver.
All your's again miles... hope you two can figure it out.
My goodness... an antique receiver and "whatever" sub. Do it right or live with what you have.
Shame because it should be a simple stereo/sub hookup. ;)
sivadselim 10-04-09, 06:25 PM All your's again miles... hope you two can figure it out.C'mon. I'm trying really hard not to step on your toes. I've given you the nod in my posts. Honestly, there's not much to figure out, here.
sivadselim 10-04-09, 06:29 PM Does the back of your receiver look like this, uppington?

If so, you're in business. All you have to do is split the pre-outs with a pair of Y-adapters. Run one branch of each adapter to the sub's line-level inputs and run the other branch back into the receiver's pre-ins. That said, there is not really much of an advantage in doing this versus simply using a speaker-level connection.

I can connect my speakers to the B terminals only without using the A button. I think these are two separate speaker systems (for use in different rooms),but can be run together at the same time using the pushbuttons.
Run one branch of each adapter to the sub's line-level inputs and run the other branch back into the receiver's pre-ins.
Not to step on your toes, but if the sub doesn't have line level outputs, that blows your theory. ;)
From what I can find... the sub only has speaker level or line level inputs only. I could be wrong. But you take your best guess.
EDIT:
I found the manual. Line level in and outs on the sub. I agree, best option. MY bad.
Page 5 of the manual shows line and speaker level connectivity options.

This is exactly how the back of my receiver looks. I think I will most likely try to use the same speaker level connections for the sub and for my speakers.

Thanks for all your help Ratman and sivadselim. I do have a home theatre receiver, a Yamaha RX-V440. The only reason I want to play CDs from my Blu ray through the Harman Kardon is that I think the Harman Kardon has a lot better sound with 2 channel stereo than my Yamaha. I am using the Pioneer Bluray as a CD player because of the excellent Wolfson DAC's in the Pioneer. And I thought that there could be a LFE signal because when I play the left and right analog outputs on the bluray through my Yamaha there is bass coming out of my sub(which is hooked up to the Yamaha with a single sub cable.

http://www.paradigm.com/en/pdf/user_manuals/OwnersManual_pdr10.pdfI didn't know it had pre-outs but whether it does or not is irrelevant to what I was recommending. All I am recommending doing is removing those jumpers at the receiver's backside and using a pair of Y-adapters to split the receiver's main outs. Use one branch of each Y to loop back into the receiver just like the jumpers but use the other branch to connect to the sub's L/R pre-ins. That's all. Figure 4 in the manual. Not Figure 5.
I think I will most likely try to use the same speaker level connections for the sub and for my speakers.That will work. As will using the B outputs. But you can also achieve the same thing with a line-level connection as per Figure 4 in the manual.
And as Ratman has brought to our attention, you could also do what is diagrammed in Figure 5 if you wanted to high-pass your speakers. It would require running one pair of RCA cables to the sub and another pair back to the receiver; no Y adapters involved. I'm not certain what high-pass the sub applies to those line-level outputs. Maybe it says somewhere in the manual.
sivadselim 10-04-09, 08:54 PM And I thought that there could be a LFE signal because when I play the left and right analog outputs on the bluray through my Yamaha there is bass coming out of my sub(which is hooked up to the Yamaha with a single sub cable.You hear bass because, as I pointed out, there is still plenty of bass encoded in all the other channels. But the LFE channel itself is being dropped.
And as Ratdog has brought to our attention...
