Question about Bose 901 EQ1915 Home Equalizer

1 Answer

No bass response out of 901's but 301's are perfect

I have tried two different receivers (pioneer sx-2300) & (Onkyo A-RV401) and cannot get a clear sound or any bass whatsoever on the 901's series iv. I also have a set of 301's that work great except when they are run through the equalizer(distortion kicks in).
Ihave new cables & have tried using different tape monitors,vcr line,...etc I even hired a disc jockey who owns a set to look at them & he can't figure it out either.
HELP PLEASE!
Thank you,

DR Kee

You should check your 901 speakers for phase.
Heres how to do it........ Remove the 901 speaker grill so you are able to see all the drivers cones. Now connect the 901 speaker wires to a 9 volt battery. Now u can check if all the cones would move forward or backward at the same time. Make sure that they all move in the same direction, otherwise you have to reverse the polarity of the driver that dont move with the rest.

According to manual there is pre/amp on Pioneer sx 20 what connections do I use to connect graphic equaliser


Yes, the SX20 includes a preamp including a phono stage. (nice!) There is already equalization in the SX20 available via the bass/treble controls. To hoop up an external graphic equalizer, you should be able to connect it to the 'Recorder' IN/OUT and then select the tape monitor input to hear the equalized signal.

Is it totaly ok to just connect one pair of JBL Control 1 speakers to this receiver? Here are some of the specs. Frequency Response: 120 Hz to 20 kHz Power Capacity: 150 W Sensitivity 87 dB SPL Nominal...


The only relevant speaker spec is the impedance. As you probably realize the Pioneer SX-255R recommends 8 - 16 ohm speakers.

Four ohms is on the hairy edge of too low. You could certainly try it but if any strain or excessive volume is used you could see something go poof!

The low end of 120Hz says don't push the bass to them.

Pioneer Elite vsx-27tx receiver with no bass!?


There may be a subwoofer mute function on your amp. The sub out is nothing more than a preamp output with a low frequency response. It is meant to be amplified by an external amp. Either check your powered subwoofer for operation or look through your operators manual for a sub mute function.

Pioneer SX-2300 powers up, but no sound.


Does the output relay click about 5 sec. after powering on? If it does check if the tape2/tape monitor is on. Check speakers and wiring. Try headphones.

There aren't any fuses for the output.

If no relay then it probably needs output transistors and a few resistors.

Onkyo TX-SR606 bass treble settings seem to make no difference


I ran into the same issue and was stumped at first. Then I noticed somehow I had changed the sound processing to "Direct" which meant the signal coming from the source was bypassing all of the control in the receiver. All I had to do is select another option (press stereo for example on the remote) and kick it out of the direct mode.

SX-1600 + KD-491F


Hi again,

It would seem that you posted the problem here also. With your kind permission, I will repost my excerpts of my responses that others may benefit on similar concerns.

A. Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.

I was made to understand that the Pioneer SX-1600 is prone to speaker output problems which could either be:
1. the speaker relay (protection); and/or
2. the amp, STK4191II Stereo Module.

Either should be relatively easy to work on and perhaps you can try the services of a locally available qualified electronic technician since the repairs would not be too specialized. The service manual may be of help (or at least a schematic , they may be downloaded from here and here).

B. To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

C. Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.
