Question about HHB Radius 50 Tube Amplifier

Output fader ineffective

The output fader on one of my HHBs is inoperative. It shows output level signal regardless of where the knob is turned. Input gain works.

Re: Output fader ineffective

It sounds as though the ground connection to the fader control has gone missing. Check with a meter.

Is there any way I can output the sound from the set to an amplifier & speakers

You need both an output from whatever it is you want sound from, as well as an input to your amplifier.
The source could have "audio out" sockets, or possibly a "headphone" socket.
The amplifier may have an "aux" input, or another input for something else that is not in use. You could edit your question and name the inputs on the amp. and outputs on your source to aid in getting advice, possibly also identifying what type of sockets are fitted.
The "audio out" would be a "line level" output, but the "headphone" output is likely fairly low level. It could still be high enough to drive into an "aux" input, worth a try.
You need suitable cables with end plugs to suit each end of the connection.

Why are the clip lights always on, and no output signal?

The clip lights measure the INPUT signal to the amp. Try lowering that level .

Why won't my MA120 fast act amplifier turn on?

A pre-amplifier allows a range of components with different output levels to connect to an amplifier. Usually one is used to allow a low-level magnetic phono cartridge to be used with the line-level input of an amplifier. These used to be separate units; now integrated amplifiers combine control function with amplifying low-level signals. They also provide tone, volume and balance control.

Buttkicker Gamer 2 Amplifier won't turn on, light stays orange when it should be green. used to be a struggle sometimes to get it to turn green by using the remote, now it just stays orange all the...

Your Gamer 2 Amp turns on whenever an audio signal is present on the input. The amp can have trouble tuning on if the output of the source (computer sound card, etc.) has been turned down. This can happen easily if you use amplified speakers - if you turn the sound card's volume control down - and then increase the volume at the amplified speaker - the resulting sound is the same; even though the signal has been lowered. The problem is that the output from the sound card isn't sufficient to turn on the Gamer 2 Amp.

Try turning down the external speaker volume, then bump up the sound card volume. You'll probably need to adjust the other inputs individually (Wave, Mic, CD, etc) so that none is too loud or soft. Once the input values have been set, gradually increase the output of the sound card in the control panel application etc. while decreasing the volume on the amplified speaker to maintain a comfortable level. Eventually, you'll find the correct volume level on the sound card output that will wake up the Gamer 2 Amp.

If you're still having trouble, review the manual, here. I hope this helps & good luck!

How to set the the bluetube dp

Setting of the DP2 depends on what type of input signal used. If the input is a strong line level,source such as the output of a keyboard or a synth module you may want to engage the Pad button and then set the gain knob to bring the average signal to 0 on the VU meter.
If you are using a condenser microphone the 48v button must be engaged and again set the gain control for an average of 0 on the VU meter.
If using a dynamic microphone, the 48v button does not need to be engaged,but it doesn't matter if it is on.
When using inputs plugged into XLR the signal can be inverted by depressing the I/O button, this will reverse the signal phase going to your multitrack (used for signal phase problems)
The 80hz button can be used to minimize annoying low frequencies (A/C rumble)present in the signal.
The tube drive knob is used to direct the signal to a 12ax7 tube drive circuit in conjunction with the main gain knob and as usual you want to keep the signal close to 0.
The clip light should not be illuminated when a signal is present,slight flickering is ok but total illumination means the signal is distorting.
This is a two channel unit so chn 2 is an exact copy of chn 1 and all controls are the same.
Most important, use your ears and listen closely to the results.

Volume output level is low on all channel.

Please disconnect your speaker and using a good 1.5 AA cell test for a good response. if Ok connect to the amp and power. Hope you are using the right source input. If not give you input to another source input and check. If not it is important to check with a signal test for the failed section. Attempt this only if you are familiar or else ask a friend to test from the output backwards to find the section which is not responding and attentuating. It sould be a possible failure in the premap/ input selection or a biasing of these circuits. Hope this helps. Good day

No stereo signal out from yamaha p 2500 s

It's unclear what type of connectors are on the end of the cables(s) coming from your computer.

This amp only works with mono 1/4" TRS and XLR connectors, not standard RCA connectors.

Did you try the Right one in the Left Channel to see if the Left Channel worked?

Refer to the following manual and read up on the connectors (page 7) and the use of the Stereo/Parallel/Bridge Switch (page 8). When it is NOT in Stereo Mode the unit only uses the Right Channel controls and input.

Use this switch to select the operating mode.
• STEREO mode
Channels A and B operate independently (as with a conventional
stereo amplifier). The Channel A input goes to the Channel
A output jacks, and the Channel B input goes to the
Channel B output jacks.
The Channel A input signal is output through both the Channel
A and Channel B output jacks. The Channel B input jacks do
not function. Channel A and B volumes can be independently
• BRIDGE mode
The Channel A input signal is output from the BRIDGE output
jacks. To adjust the volume, you must use the Channel A volume
control knob.

Carver stereo amp will only play

That should be normal. The main inputs usually go directly to the power amp. If you want volume control, put a mixer with faders beween them... Radio Shack used to have some inexpensive mixers.

Eltax avr-200 no sound

Eltax AVR-200 will start up in protection mode if the amplifer went into protection mode due to high volume before it was turned OFF and it will start at the same volume level as it had before power OFF.

To correct this you must shift to another input without signal, then turn the volume down before it goes into protection mode again.
