    Replacement speakers for TC electronics BC208 technically I suppose that my cabinets are in the warranty. I have one speaker driver that is functioning but started to smoke the other evening while I was performing. I would like to get it replaced and would also like to purchase additional ones to have spares if this happens again. I own two Of these cabinets

    I have the pre-amp tube model and I need to understand how to use the Gain, Volume nand Master come into play to to set the overload light.

     

    I've read on Talkbass, that one should set the Volume all the way down and then set the light using set the Gain. I've tried many combinations and have failed. To me, for the master , it should not matter where that control is. 

     

    Is there a schematic to undertsand the signal order, that would help

     

    Thanks for any help!

      WilliamR The GAIN knob adjusts the amount of preamp level. The general rule of thumb is when the clip light is blinking, the bass tone starts to go into preamp distortion.
      VOLUME knob (BV1001T only) compensates for boosts in the signal from the GAIN knob. It also affects the level of the FX LOOP SEND jack.
      The MASTER knob adjusts the overall output of the amplifier. The general rule of thumb is to start with the master volume low and dial in your gain and overall channel volume to get the tone you desire, then the master volume controls the overall output to your speakers without changing the tonality of your tone you just dialed in.

      Are you saying the only way to control the LED is from the bass itself? When you turn down everything LED will still light up. For example- if want to be clean, I'd estimate the master position. Pin the volume and use the gain as a volume control. I don't use effects

    Hello, I have purchased a Bugera 15BXDA bass amp and have some questions about the lights. 

    I use a lot of fuzz and distortion on my bass and the the red clip light keeps flashing. Can that damage my amp and what can I do to remedy that issue?

    Also, the orange light that circles the volume knob turns red. Why does it do that and what can I do to address that issue?

     

    Thank you

      PedroRodrigues Hi Martin, please see below as you will have a image with the full information about what the lights on your unit and what they mean. If effectively your unit is not behaving as it should please follow the link below to submit a assistance request for your unit https://community.musictribe.com/pages/create-new-ticket?type=service%20request

      Deftones210 Yes I have that paper. But you have not answered my questions. Will the clipping make long term damage to my amp?

      Deftones210 Also, what does it mean when the orange light around the volume knob turns red? That is not in they manual.

    I was watching a review for the BH800... I assume it is more or less similar to the BH550 with only the wattage differing. 

    https://youtu.be/OIFHh2mLg5c

    The reviewer indicated the BH800 was a class D power amp and therefore has a slower attack than other amplifiers.

    I've never heard amps described that way before, can anyone help me understand what it means?

      PedroRodrigues Hi, Jkblight thank you for your post, please take in to account that there are two basic types of power amplifiers: linear and switch-mode.
      The Class-D amp is a type of switch-mode amplifier that consists of three stages: the input switching stage, the power amplification stage, and the output filter stage.
      A common misconception is that a switching power amplifier is an amplifier with a switching power supply.

      A switching power amplifier utilizes switching technology as a means to amplify the signal, whereas a switching power supply is using switching to provide AC mains power.
      In linear amp designs, the output power transistors amplify the incoming signal analogous to the input signal (same signal only louder).

      In a switching amp, the incoming audio signal modulates the width of an ultrasonic square wave in the output transistors.

      This modulated square wave is then low-pass filtered. The result is the amplified analog signal sent to the speakers. This signal processing is called Pulse Width Modulation or PWM.

      In operation, a switching power amp uses several pairs of power output transistors with each pair operating as switches (transistors can operate either as amplifiers or switches) in a push-pull arrangement. One transistor of each pair turns fully on (saturation) while the other is off, then they alternate.

      One transistor always produces a positive voltage when it is on; the other always produces a negative voltage when it is on. When a transistor acts as an open switch, the current through it is ideally zero.

      When the same transistor acts as a closed switch, the voltage across it is also ideally zero. Whether the switch is open or closed, the power dissipated as heat – current times voltage – would ideally be zero. The result is less power wasted, which means improved efficiency – theoretically 100%.

      Since the output transistors develop almost no current (when off) or no voltage (when on), they produce almost no power wasted as heat. Increased efficiency requires less power from a power supply and smaller or no heat sinks for the amplifier.

      These are important advantages in portable battery-powered equipment. Since the class-D amplifier works in an on/off mode, people mistakenly think that the “D” in class-D means “digital “.

      This is not the case.

      There is no digital coding of the signal. The function of class-D is based on analogue principles.

      Class-D amplifier applications range from battery-powered portable products such as mobile phones, high-end professional amplifiers, musical instruments, and home multimedia systems.


      Please take in to account that I have seen other customer asking information about the same thing and it is difficult to make generalizations, especially when we are referring exclusively to the amps since much is also related to the speakers.
      Nevertheless "fast vs slow" has a lot to do with the bass and it's much more about the transients and the attack.


      Please take in to account that there is no right or wrong or better or worse when it comes to the perception of fast vs slow, as this is a case of perception some Amp may be faster for some and the same Amp may be slower for other.

    Last week I asked the following question to the spare parts departement:

    Buttons and knobs of my RH750 are cracked.

    All the preset buttons of my TC Electronic RH750 are cracked. Same with gain and volume knobs. I know it's a defect that appears on the majority of these models. Is it possible to send me replacement buttons and knobs free of charge? And the instructions of how to fix them by myself. 

    I received an email with a ticked number (Ticket Number: CAS-583910-F8T8N2) But I have never had any other news since that time. May I know if someone is taking care of my request?

    Thank You for your help!

    Hi all -

    I have an RH450 bass amp head that I bought in the USA a decade ago.  I recently moved to the UK.  Can I simply swap the USA power cable for a UK one like I do for my computer?  Or do I need to plug the unit into a step-down transformer to externally convet the 220 volts to 110 like on my vintage amps?

    Thanks!

      DavidKnighton Hello Agent00Soul,
      The device has a universal power input that will accept a range of AC Mains voltage from 100 ~ 240 Volts. All you need to do is find the correct AC Mains IEC plug for UK and let er rip.

    I turn it on and it lights up a weird set of lights and does not play. It's stuck in this mode. Clip light, TubeDrive Light, E and A tuner lights, Flat tuner light and Power light are all lit solid. No sound.
