Owner's Manual 222 We all... ... produce electronic waste! It's just a matter of time! We here at Ampete Engineering are not only consumers, like you yourselves, but also engineers of electronic products that we want to place into a modern world. Here it looks at first glance that everything has been invented already.

Owner's Manual 222 Introduction The 222 is designed to combine guitar amplifiers, guitar cabinets and guitar effects! Where our bigger model 444 is for the very few Pros amongst us, the 222 is designed for all of us who have to carry their equipment by themselves. And to be honest, who ain't one of those? The 222 is made for all those guitarists, who don't want to relinquish the huge differences of speakers and cabinets.
Owner's Manual 222 Front Panel 1. FEED THRU: Jack for an ungrounded direct signal connection from/to the backpanel FEED THRU. Use it for connecting tuners, wireless systems or any connection you need from back to front without using long cable connections. 2. BUFFER IN: Front Panel instrument input, which routes the instrument signal to your connected amplifier inputs via a high to low impedance buffer, for keeping signal clean and noiseless without coloring it. 3.
Owner's Manual 222 Rear Panel 1. DC In Jack: Connect a 18-24V, 0.6A DC power supply for powering the 222. The power supply included in delivery is verified for best performance and can be used in most countries providing 90VAC to 240 VAC line voltage. 2. GROUND LIFT: Controls whether the 222's audio ground is connected to the metal chassis or not. The chassis is grounded when the switch is in the 'Out' position. Note that the DC power supply does not provide a connection to earth conductor.
Owner's Manual 222 12. FX OUT: Connect the FX OUT jack of the 222 to the Output of your effect, whether it is a single unit like a delay pedal, a chain of pedals or rack units or another audio looper. This is exactly like you would connect it to your amp's FX Loop Return. When switching between amps on the 222, it automatically switches your effects to the currently selected amp. 13.
Owner's Manual 222 Controlling the 222 via the front panel Selecting Amplifiers and Cabinets / Switching rules & protection At this point you hooked up your amplifiers and cabinets to the 222. Let's start switching! You should establish a certain operating process when operating the 222. Either in the operating way via the front panel switches, or when programming midi presets, a cabinet has to be chosen by pressing the corresponding front panel CABS switch.
Owner's Manual 222 Stereo Mode The stereo mode surely requires two amplifiers and two cabinets connected to the 222. It can not be activated if only one cabinet is connected. Activate the Stereo Mode by pressing and holding „SAVE/STEREO MODE“. All AMP and CAB switches light up to display AMP1 is connected to CAB1 and AMP2 is connected to CAB2. The guitar input signal is split to both amps, which gives the opportunity to use two amps and two cabinets as a stereo setup.
Owner's Manual 222 Controlling the 222 via MIDI Checking and setting the MIDI Channel By pressing the MIDI CHANNEL button, the display will show the currently active MIDI channel. This is indicated by an additional decimal point at the lower right corner of the display for only a few seconds before the display switches back to the MIDI program number. To set the MIDI channel, consecutively press MIDI CHANNEL for a short period of time. The displayed number counts up to '16', and starts again at '0'.
Owner's Manual 222 If you are using a MIDI controller pedal with a let's say more simple software structure – meaning the controller pedal does not „know“ which amp or cabinet is currently in use - or if the number if CC messages in a preset is limited, it might work for you to use the 222 Control Change mode „1“. In this mode the 222 only processes Control Change messages having the value 127 („switch on“), after switching off every amp or cabinet which is currently in use.
Owner's Manual 222 Grounding As mentioned before the default setup of the AMP1-2 GND LIFT switches should be both „In“. This is because the necessary ground connection is already present via the amplifiers speaker output. Usually this is the best solution for avoiding ground loops in your setup.
Owner's Manual 222 Troubleshooting Problem: No signal when an amplifier (AMP1 or 2) is chosen. Make sure all amp inputs and speaker outputs are properly connected. Never mix amp in- and outputs to different amplifiers! Problem: No effect signal when switching FX loop. Make sure the FX Loop of the chosen amplifier is connected correctly to the 222s matching FX Loop.
Owner's Manual 222 A word on impedances When it comes to impedances and matching of valve amplifiers and speaker cabinets, there have been written a lot of words and there have been told many opinions, myths and beliefs. And as it is so often in our world, all of them are in between the truth and the untruth. Some more, some less.
Owner's Manual 222 The diagram below shows some simple measurements (in that particular case taken with our Amp TWO, a 110 Hz, 150mV sine wave, which is similar to the 'A' strings first harmonic of a Humbucker guitar). The amp impedance switch has been set to either 4 (blue color), 8 (orange) and 16 (yellow) Ohm and in every of these settings a reactive load of 2, 4, 8 and 16 Ohm has been attached to the power amp. Let's point out only the two essential characters. 1.
Owner's Manual 222 But even if the power decreases by almost one third compared to a matching load, the subjective impression will be the volume is nearly the same (as long as the phases of the speaker cabinets are the same). This is simply because more speakers are now driven by the amplifier. You will notice a slightly different feel, which is caused by a different damping factor the power amp of your amplifier 'sees'.
