I cannot get equal volume on both channels. It snaps crackles,

The Bose 901 speakers require the use of a specific equalizer that is designed to optimize their performance. If you have a Bose 901 equalizer, you will need to connect it to your Lafayette 3500 receiver in order to properly use the speakers.
Here are the general steps for connecting the Bose 901 equalizer to your Lafayette 3500 receiver:

1. First, ensure that the power is turned off on both the receiver and the equalizer.
2. Locate the preamp output jacks on your Lafayette 3500 receiver. These will typically be labeled as "pre out" or "line out".
3. Connect a pair of RCA cables from the preamp output jacks on your receiver to the input jacks on your Bose 901 equalizer. These jacks are typically labeled as "preamp in" or "line in".
4. Next, connect another pair of RCA cables from the output jacks on your Bose 901 equalizer to the main amplifier input jacks on your receiver. These jacks are typically labeled as "main in".
5. Turn on your receiver and equalizer, and ensure that the volume levels are set to a low level before playing any music.
6. Set the Bose 901 equalizer to the "On" position, and adjust the various equalizer controls to your preferred settings.
7. Finally, play some music and adjust the volume levels as needed. You should notice a significant improvement in the sound quality of your Bose 901 speakers with the equalizer properly connected.

Note: It's important to use the Bose 901 equalizer specifically designed for the speakers. Using a different equalizer or not using any equalizer at all may result in poor sound quality or damage to the speakers.

To reset the equalizer settings on a JVC RX-5042 audio receiver, you will need to follow these steps:

1. Press the "Menu" button on the receiver.
2. Use the arrow buttons to navigate to the "Sound" menu, and then press the "Enter" button.
3. Use the arrow buttons to navigate to the "Equalizer" option, and then press the "Enter" button.
4. Use the arrow buttons to navigate to the "Reset" option, and then press the "Enter" button.
5. Press the "Menu" button to exit the menu and save the changes.

This will reset the equalizer settings to the default values. If you continue to experience issues with the bass level when the volume is turned up, you may need to adjust the equalizer settings manually. To do this, follow the steps above to access the equalizer menu, and then use the arrow buttons to adjust the levels of the different frequency bands (bass, mid, treble, etc.) to your liking.
I hope this helps! If you have any further questions, don't hesitate to ask.

1
Hook up your equalizer to your receiver if it does not have preamp-out channels. The equalizer should always be between the receiver and the amplifier. Your amplifier will need integrated preamp-out and preamp-in connections to work with this method.
2
Purchase 2 pairs of RCA cables. To run a signal from your stereo receiver to the equalizer and back again, you'll need 2 sets of RCA cable (the same kind that is usually used to connect source components like turntables and CD players).

• The length of the RCA cables should match the length of the distance between the receiver and the equalizer.

3
Connect one pair of RCA cables between the receiver and equalizer. Connect one pair of cables to the tape monitor output channels on the receiver and the other end of the cable to the left and right channel inputs on the equalizer.

• You will usually find these channels on the rear of the equalizer.

4
Connect the other pair of RCA cables between the receiver and equalizer. Connect the other pair of cables from the output channels on the back of the equalizer to the tape monitor input channels on the back of the receiver.

• Right channel jacks will usually take the red colored RCA plug while left channel should take white or black RCA plugs.

5
Use your equalizer. Turn on the receiver and switch the front panel output control to the "Tape Monitor" setting. This opens the tape monitor channels and means that the sound will travel through your equalizer before being sent to the amplifier. Adjust the equalizer knobs according to your preferences.

• You should now be able to manipulate the controls on the equalizer to change the frequency response or tone of your music.
• To switch on the "Tape Monitor" setting you should depress the button on the front panel of the equalizer.
• If you have a tape deck connected to the tape monitor channels then you will have to remove this before connecting your equalizer.

the problem is your equalizer adjust your equalizer

Sounds like a faulty / worn fader. If it does it on all channels then look at the master fader 1st.

The order is mixer, equalizer and amp. The output of the mixer connects to the input of the equalizer and the output of the equalizer connects to the input of the amp. The equalizer has three types of input and output connections. They are XLR, 1/4 inch and screw terminals. The mixer will have one or two of the three. Choose XLR if possible on the mixer, choose line level output on the mixer if possible. A XLR male to female cable is needed for the connection. The equalizer has two channels, if the mixer has two output channels the two output channels of the mixer can connect directly to the two input channels of the equalizer. If the amp has two input channels, the two output channels of the equalizer can connect directly to the two input channels of the amp. If the mixer only has one output channel then only one channel of the equalizer can be used and one channel of the amp likewise. A XLR male to female connection cable can be used to connect the equalizer to the amp.

I ended up installing a stereo graphic equalizer/ sound limiter from Radio Shack. I use the ear phone output go into the equalizer / sound limiter then go into a speaker system. You can adjust the EQ and limit the volume. I also had problems with load portions of movies, commercials and low/ high audio. This also allows sound enhancement with some buttons on the EQ. It is usually used in sound reinforcement as in Band and public address systems also higher end stereos systems. you will need a set of powered speakers for this solution so the EQ has somewhere to go to.

It sounds like you may have a bad cable. The most common place for a small gauge cable (such as RCA, TPS, XLR, etc) with metal connectors to fail is in the stain relief which often fails to live up to its name. An easy way to check this is to grab the cable near the connector and wiggle it. If the sound crackles and changes volume levels suddenly then you may want to try a replacement cable. If the replacement doesn't help, you should use a contact cleaner such as "Blue Shower 2" that is approved for electronics use. Make sure your mixer is switched off and disconnected from its power source before using any cleaners to avoid any risk of electric shock. Apply the cleaner to all exposed output connectors on the mixer. Hope this cleans up your output prolems

I have same problem

take output from left and right from equalizer and go to line in any two channels inputs in peavey mixing console and adjust your level with faders and other control knobs.
