Although it just looks like it’s no more than just two jack inputs, a “Send” and a “Return”, there is so much more behind it! The Recording/PA output offers you a Speaker Emulated sound coming from a microphone placed in front of your speaker cabinet. The more you open the tap, the lower the resistance gets for the water and the higher the water current becomes, and vice versa. To celebrate 30 years of Koch Amps we have some special Koch 30th Ann T-shirts and 2 new special t-shirts that matches the new “The Greg” signature amp. In a tap water installation, the current is the water flowing from the tap. The only two effects available were reverb and tremolo and top of the line models had one or both effects built in. Especially tube amps for guitar do not generate a constant output voltage. With the OTS Drive control you can add a great sounding tube saturation to both Channel 1 & 2 while the OTS Volume control allows you to boost (or cut) your volume. As we saw above less current is the result of a higher resistance. The Koch Superlead also features both pre and post FX loops for adding tone shaping pedals before the pre-amp, and modulating pedals after the pre-amp. The Powertone-III also features two separate switchable Master Volumes. A speaker on the other hand has an ohm value that depends on the frequency, therefore this ohm value is called AC resistance or impedance (Z). The lowest value is 3.47 ohm (at 400Hz) and the highest is 12 ohm (at 20 KHz). This means that when a speaker loads the amp, the power which the amp generates depends on the frequency, because the impedance of the speaker varies with the frequency. Parts such as output tubes and output transformers are not able to withstand these high voltages which often results in severe damage to those parts. Both taps together will supply twice the water current. Since the introduction of the first “Radiola” moving-coil loudspeakers in 1926, we use the word “impedance” to define how much a speaker loads an amplifier. With the footswitch you can switch from Rhythm to Solo volume giving you more power to make sure your solos will always be heard. Koch Jupiter 20 Watt Junior Combo Koch Amplifiers Dealer Canada "Shop Where The Pros Do" 604 682 4422. Isn’t ohms used for resistors? An amplifier sends this audio signal as a current to the speaker. Koch Amplification. A tube amp tries to maintain its output power and as a result of that it raises its output voltage if the impedance of the load gets higher. If a tube amp gives full power at a 4 ohm load, it might generate even 70% or more of it’s power at 8 ohms (instead of 50%). The amp is the key to the door marked ‘tone’. From pristine clean tones all the way through to exciting high-gain tones with infinite sustain the Powertone III will amaze you. On the other hand, if you connect two speakers in parallel (see diagram below or, by plugging the second speaker in the extension output of you amp or speaker box), both speakers will draw current from the amp. Normally, full power is given at 4 ohms, half power at 8 ohms and a quarter power at 16 ohms. In a tap water installation if you place a second tap behind the first tap (in series), the second tap lets only a part of the water through that comes from the first tap. A resistor has the same ohm value throughout the whole frequency area, this ohm value is called resistance (R). The picture to the left shows how the impedance of an average 4 ohm speaker varies with the frequency. Koch Greg Koch Signature Amp Koch Amplifiers Dealer Canada "Shop Where The Pros Do" 604 682 4422. In a tap water installation this is the same as using a second tap next to the first tap. Another new feature on the Powertone III is the OTS circuit. Koch Amps are the Dutch leaders in the design and manufacture of guitar amplifiers. As you might know, the output power of solid state amps varies with the load resistance of the speaker. In order to accommodate a Koch speaker cabinet or any other extension cabinet, the back panel of the Powertone III features five speaker output jacks for connecting 4, 8 or 16 ohm speaker cabinets. Koch amps and amplifier accessories ensure that sound is delivered flawlessly. We use only the highest grade components for the best sound and reliability, plus we have housed the Superlead in a heavy duty, yet light weight aluminum housing. Building the best Combos, Heads, Cabinets and Powersoaks. The OTS circuit should be considered as an on-board effect unit which you can turn-on or bypass with the footswitch. integrating the amp in a rack system. In true Koch tradition, all final assembly and production of the amps is done at the Koch factory in The Netherlands to meet the highest quality standards. The remote control input can be used with midi switchers or other external switching devices. With the added Drive control Channel-1 offers a greater variety of tones while preserving the wonderful warm and crystal clear tone of the Powertone I and II. Whether you use overdrive pedals to provide your gain, or you're looking for your amp to provide full bore distortion on its own, the amp you go for will determine the overall character your audience hears out front.. Nowadays, an effects loop is an integral part of almost any musical amplifier. So if you play a tube amp and disconnect the speaker the load gets unendlessly high and the amp will raise its output voltage to very high levels (thousands of volts inside the amp). You guessed it: it's "The Greg" by Koch Amplifier... 500 S Arthur Ave, Suite 700, Louisville… All these functions can also be accessed by a MIDI switcher via two separate jack inputs to allow maximum flexibility when e.g. So keep this in mind if you have a tube amp; always connect a speaker or a dummy load to your tube amp, never play it without speaker or power attenuator/dummybox connected. Impedance or resistance is the matter in which the speaker resists the audio signal. The only two effects available were reverb and tremolo and top of the line models had one or both effects built in. Finally, there is a balanced XLR DI output with line level signal, speaker emulation and ground-lift for connection to recording or mixing consoles, and a 1/4" output with switch-able levels for connection to any type of amp or monitor. Koch Dummybox Koch Amplifiers Dealer Canada "Shop Where The Pros Do" 604 682 4422. Later, when effect units became available (wah-wah, delay, chorus, flanger). Consequently, there's no output transformer, which reduces the overall weight by several kilos. And isn’t a speaker a totally a different thing than a resistor? As we saw above more current is the result of a lower resistance. Koch's Jupiter combo is a hybrid design, which blends a pair of 12AX7 preamp valves with a clever solid-state output stage that promises to provide all the dynamic punch and sonic warmth of valves. Koch amps and amplifier accessories No matter how clear and distinct a guitar sounds, the delivery of that sound through a Koch Amplification system will determine how well it is received by an audience. Depending on the output power, the power section features either two or four EL34 Power tubes. The other functions: Channel 1 & 2, Gain Boost, OTS on/off, Master I and II can all be switched by the included FS4 Footswitch. The two effects loops on the back panel offer you the possibility to connect your effects unit in series or parallel. Parallel Effects Loops, Guitar Speakers Explained | The Basics, Series & Parallel Wiring. In this article I will explain the basics of guitar speakers such as the Voltage, Current, Impedance, Series and Parallel connection of speakers. We’ve got some new designs for you "made by Sweetest design" in Amsterdam! With tube amps this is totally different. In addition to that, the new Depth control gives you an incredible boost in the low end.
