With the development of hard rock in the s and s the need for ever louder bass amps led to the use of stacks—amplifier heads mounted atop large speaker cabinets. This approach makes for a cleaner, more controllable sound mix. That said, many bass players performing in smaller theaters and clubs still use on-stage rigs. One trend that has impacted bass players of all stripes is the move to more compact and portable solid-state and hybrid amplifiers. Hybrids Until the s, most bass amps used vacuum tubes, and a few higher-end models still do. Some bassists prefer what they perceive as the warmer, more-natural sound that tube amp circuits produce. Tube-based amps produce a form of distortion when overdriven that is pleasing to fans of old-school bass sound. In comparing amp wattage, keep in mind that watt-for-watt, tube bass amps are considerably louder than solid state amps with similar power ratings.

Connecting an Extension Cab to a combo

It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit?

Oct 22,  · Learn how to properly connect a guitar amplifier to a cabinet in this free instructional video clip. Expert: Tim Ambrosuis Bio: Tim Ambrosius is professional guitar technician and manager at.

The amp head is typically placed on top of the cabinet. This configuration is so named because many professional guitarists began using two 4×12 cabinets with an amp head on top, or a “full stack,” in the early ‘s. Half stacks became popular as live sound reinforcement systems improved, and the need for high stage volumes decreased. A half stack is simple to set up with a few cables. Place your amplifier on top of your speaker cabinet so it sits level and secure.

Locate the impedance rating of your speaker cabinet. This rating should be clearly labeled near the input jack on the back of the cabinet. If your cabinet offers stereo connections, start with the left input. Connect the other end of the cable to the speaker output jack of your amplifier. If your amplifier offers more than one connection for different impedance ratings, choose the one that is equal to or greater than the rating of your cabinet.

Tip If you are using a tube amplifier in your half stack, remember not to power on the amplifier–unless the speaker cabinet is connected to it. This can damage your amplifier. He has written for “Connections Magazine,” and is a frequent blogger on several consumer tech sites.

In other words, you can check up on your tuning state at any time — even at a quick glance in the middle of a tune. And tuning up between songs is faster then ever. Crowds just hate waiting! You can create 3 presets tailored for e. TubeTone TubeTone gives you that vintage feel of an all—tube bass amp.

Jun 25,  · Note that you don’t need a “guitar amp.” Your Spyder already provides all the preamp functionality, so you only need a power amp and your extension cabinet. I picked up a Carvin TS 50W/50W (or W bridged) all-tube stereo power amp used .

One day I started to scribble a cabinet on a piece of paper that was flying around and half an hour later the plan was laid out. I looked up an existing speaker enclosure to get the proportions right and did not bother to spend much time on speaker cabinet size calculations, which you should do if you plan to build HiFi speakers. You can find this article here on the Celestion Website. There are basically two types of guitar speaker cabinets: Again if you search on the web to know what the differences are you will find tons of information and as usual, sometimes highly contradicting opinions.

The biggest difference is how the sound is distributed. An open cabinet will also emit sound through the back and from that alone you get a room filling sound experience even on low volumes. Closed cabinets are more directional and usually put more emphasis on the mid and low frequencies. There is a really exhaustive and informative article on guitarplayer.

Power Amp Buying Guide

Lots of musicians playing this instrument connect it directly to bass combo or mixer. This type of connection results in serious deficit in sound control possibilities. The purpose of Bass Equalizer is to compensate for this deficit. The seven equalization bands of this device have been singled out from bass guitar sound spectrum for precise and operative sound correction during a concert or studio recording session.

Oct 22,  · You should match the ohms on your amp’s speaker output to the cab you are using. Without going into a great amount of detail, as you add speakers, the demand on your amp can .

Posted 05 January – Spooki, You may have done this already, but you would need to have no connection to any speakers when you test the amp speaker leads to chassis ground. Does the amp have a grounded AC power cord plug or just a 2 wire style? From 0 to full positive amplitude back to 0 then to degree out of phase neg full amplitude back to 0 again.

Just for my own curiosity, why are you wanting to seal the speaker box? You just need the sound off the back wave of the speaker to have enough time delay before coming around the front to avoid a cancelling effect. Glad you found the “tracer” on one of the wires. If you are still really concerned if it is correctly negative you will need to test to ground. Most amps use ground as a common potential from the transformer, but not all.

Best of luck Aster Hi again Aster. You have been great help throughout this and I follow you on the cone movement. It makes perfect since to me and I’m happy with that. I can’t tell any difference either way regardless. I just play at home and never push that hard anyway.

Connecting an Extension Cab to a combo

In reality, a lot of these variables are mutually exclusive: If you want maximum power output, be prepared to pay more for the drivers and sacrifice some frequency response. Keep these things in mind as you read over the next sections. A Note on Speaker Selection Don’t skimp too much on the speakers: However you can have all of the above qualities without spending a fortune.

Aug 28,  · Can I hook up a 1×12 combo amp to a 2×12 cabinet and use all three speakers? Discussion in ‘Amp Tech Center’ started by sixstringguy, Aug 16,

How do you hook up a 1 farad capacitor to your amp? Answer 1 You first have to determine which side of the cap is positive andwhich side is negative. You run a wire from the negative side tothe chassis and …for the positive side you run a cable from thebattery to the terminal and from the terminal to the amp. Be careful not to mix up positive and negative on the capbecause it could explode and cause damage. Answer 2 Because the capacitor is used to filter changes in supply voltageto the amp, the capacitor should be as close to the amp aspossible, and connected with heavy wiring.

The capacitor also actsas a huge reservoir to supply lots of current as the amp signalhits high levels. By providing plenty of current when it is needed,distortion in the sound is minimized. The key is lots of capacitance, as close to the amp as possible,and thick cables capable of carrying lots of current. Answer 3 Be very careful with that thing. The current output of a capacitoris the product of capacitance, in this case 1, and the change involtage with time.

Thus, if you do something to cause a quickchange in voltage with that, you will get a very large currentspike, possibly hundreds or even thousands of amps. Also note for this reason you should really pre charge capacitorsof this size. Let’s say you have 1 ought wire run from your batteryto the cap, with a resistance of. I actually have noidea what the resistance of your wire is, I just made that up forargument’s sake When you connect the discharged capacitor, you arecausing an instantaneous change in voltage.

Can a hammond organ plug into any amp or speaker cabinet?

Overall, I feel very confident in this purchase. Having played through many amps through the years, I’ve gotten to the point where hauling around a rig heavy enough to produce lots of sound Read complete review Overall, I feel very confident in this purchase.

When you hook up more than one speaker to an amp, there are two ways they can be arranged: in series, or in parallel. Series means chaining the cabinets together one to the next. Parallel means sending one output of the bass amp head to one cabinet and a second output from the head to another cabinet.

What Is a Combo Guitar Amplifier? By Matt McKay ; Updated September 15, A combo guitar amplifier includes all amplifier components in a single enclosure. Unlike separate “stack” amplifiers, where the amplifier and speaker cabinet are individual units, a combo amp is self-contained and designed for portability. Combos come in sizes, configurations and power levels to suit every need, and are popular with beginners and professionals alike.

Benefits The benefits of combo guitar amplifiers are portability, ease of use and–on some models–expandability. No separate connection of the amplifier and speaker is necessary for normal use, but some combos can be attached to larger external speaker cabinets or additional amplifiers, if desired. Depending on the make and model, combo amplifiers have all the power and features of stacked amplifiers, but with fewer speakers.

Considerations While combo guitar amps offer many benefits, their only limitation is the number of built-in speakers. With few exceptions, combo amps come with one speaker for lower-powered models, and two for higher-powered models. In comparison, half-stack amplifiers typically use four speakers, while full-stacks use eight.


I am reading and trying to understand amp ohms. So here is my question. Please see the link for the Fender Deluxe Reverb reissue head. I’m not affiliated with Sweetwater. I’m just trying to show something, and it has the best picture that you can zoom in to see what my question is. On the back of the amp it has “Int and Ext” speaker jacks with 8ohms total.

Feb 28,  · You can run your headphone jack to amp or power amp then to another speaker. Like a line out. Keep the volume on your practice amp low so the headphone jack won’t overpower the amp .

Ask Question Step 7: The Heater Power Supply s Unfortunately, the filament secondary for my power transformer isn’t a separate winding, and doesn’t have a center tap. Maybe I could disassemble the trannie and see if the coils could be separated Placing two large diodes in parallel but opposite directions in an AC supply limits the voltage by the voltage-drop amount. That dropped the filament voltage right to 6. The two-diode trick works only for AC–current flows through one diode at a time, dropping that half of the waveform by the diode’s voltage drop amount.

One diode would do the trick for DC. Plan B However, they weren’t quiet. You really need separate windings to setup a false center tap, which can be used to quiet the heaters.
