1. response usually preferred for higher gain rock tones In the modern setting it also turns off the tube rectifier which is helpful in case the EZ81 rectifier tube is bad We recommend to set the switch to vintage at the time you turn the power on then wait 20 seconds before you switch to modern see the power switch topic power attenuator switch back panel This switch gives you three power settings in the middle position you have the full 18 watts for maximum headroom From there you have the choice to set it to 5 or 1 watt ft sw foot controller back panel Plug here the foot controller in You have two switches the right one lets you switch from clean to overdrive led illuminated the left one lets you switch between the solo and crunch led illuminated channel If you switch from the clean channel to the overdrive it will depend on the left switch which one of the two overdrive channels is on cr gain back panel As previously explained above the cr gain control lets you preset the crunch gain which is the difference in gain between the crunch and solo channel With this control turned up all the way the crunch channel has essentially identical gain as the solo channel This is useful if you would rather have channels with identical gain but want two different switchable volume settings speaker outputs back panel You have the choice of 16 8 or 4 ohm output impedance please use the value which matches your2. lets you select one of the three channels if no foot controller is connected The front panel display lets you know which controls are active Whatever control is illuminated at a certain channel setting can be used to alter the sound 60 70 80 toggle switch This 3 position switch works on the crunch and solo channel and will give you the option to find the right gain structure for guitar pickups and musical style 60 produces lower gain plexi and bassman tones you have to set the gain high for overdriven sounds otherwise the amp stays pretty clean which of course gives you the option to use it as a second clean channel as well This voicing works well in combination with high volume settings for dynamic cranked power amp overdrive 70 bumps up the gain and slightly narrows the frequency spectrum to give you a more focused high gin sound 80 has the most gain due to the high compression the volume gets cut and needs to be readjusted This mode is also good for very low volumes gain control This control sets the amount of gain for the crunch and solo channel Important Located on the back panel you find the cr gain control This one lets you preset the crunch gain which is the difference in gain between the crunch and solo channel With this control turned up all the way the crunch channel has essentially identical gain as the solo channel This is useful if you would rather have channels with identical gain but want two different swit
3. speaker cabinet A speaker or other load must be hooked up before you turn the Atma on otherwise you risk damaging the output transformer If you want to hook up two cabinets you need to get a splitter box which gets hooked up to one of the three outputs always just use one never two or three outputs at the same time If you have two cabinets with the same impedance hooked up to a splitter box the single out put with half the impedance value must be used Example two 16 ohm cabinets connected to a splitter box the box gets connected to the 8 ohm speaker output only line out back panel The line out is a frequency adjusted line level signal from the power amp A speaker cabinet or other load needs to be hooked up at all times Due to space restrictions a 3 5mm mono connector is used speaker cabinet not included with the head The complimentary 1x12 open back speaker cabinet features an aluminum shell construction with a screwed in Baltic birch baffle board It comes loaded with a Celestion G12H30 at 16 ohms Troubleshooting Make sure you read and understand the safety instructions Repairs should be done only by knowledgeable Technicians Always make sure your Cables Guitars Effects and Extension Cabinets are working and hooked up correctly If you think something is wrong with your Amp play straight into the Amp with nothing else hooked up other than a Guitar That way you make sure it is the Amp If you own a combo unplug the inter

5. chable volume settings tone control This control attenuates the tone and gain characteristics of the clean channel A lot of thought has been put into the design to have a very flexible clean channel with just a tone volume control and a bright switch It is best to start out with it set half way and see it as a neutral position From there if you turn it down you will get less gain with more highs and bass for the typical scooped blackface sound Turning the control up will add gain and midrange growl reminiscent of the classic tweed tone bass middle and treble controls Let you control the bass middle and high frequencies of the crunch and solo channel volume controls These controls let you set the loudness of each channel independently from each other bright switch This switch lets you choose a dark neutral or bright position and works for the clean channel only Note the higher the clean volume is set the less effective the switch becomes power indicator light This light indicates that the amp is powered on it is also sensitive to the input level and will flash along with your strumming dynamics power cable socket back panel This socket connects the Atma to the main AC voltage it is recommended to have the power switch in the off zero 0 position Plug the supplied cable first into the amplifier and then into your wall AC socket Make sure your amplifier is made for the correct voltage of your location The power cabl
6. e socket also has a little pull out fuse holder it contains the main fuses To pull the fuse holder out you must disconnect the power cable first use a little screw driver to pull the holder out Please note it does not detach from the socket The holder comes with two fuses the inner one is the actual one used while the outer one is a spare power switch back panel After connecting a speaker cabinet or other load and with the power cable connected you can turn the power on flip it from O to 1 the pilot light on the front will light up Please note the Atma has no standby switch to extend tube live we recommend to have the vintage modern switch set to vintage so the EZ81 rectifier tube is engaged which will raise the voltage very slowly and therefore protect the tubes and filter capacitors from voltage peaks fx loop back panel The Atma has a buffered series effects loop between pre and power amp Connect the send to the input of an effect and the return to the output The loop circuit is completely out of the audio path as long as nothing is plugged into the send jack The send signal still feeds directly into the power amp as long as nothing is plugged into the return jack This can be useful if you just want to send the preamp signal to an external power amp etc vintage modern switch back panel This switch is in the power amp circuit and lets you have either a wide open dynamic vintage or a more dense and tight modern
7. nal speaker and hook up an external speaker cabinet to make sure it s only the amp which is faulty For noise check the appropriate preamp tubes refer to f Tubes are delicate and have a limited life span depending on operating time temperature and mechanical influences 99 of all sound and noise problems come from preamp tube failure We let our amps run for at least two days before we ship them to make sure that the tubes work properly but since they have glass housing and delicate little plates inside them it is possible they were damaged during shipping Please don t feel discouraged We don t manufacture tubes and can only retest them to make sure they re okay Fuses To check the fuses use an Ohmmeter to make sure they re blown because sometimes you can t see if they re blown The Atma uses a 1A slow blow 5x20mm type as main fuses located in the power cable socket on the back panel Due to the small chassis the Atma has no H T fuse If the main fuse s blow s it could be just a voltage peak from your power outlet Put a new one in and see what happens If it blows again please contact us There you have it It s all up to you now be creative and push your musical imagination For Questions call or visit out our website bogneramplification com
