Plug into the high or low gain input jack. 2. Set the post gain control around mid point. 3. Set the pre gain control somewhere in the middle of its range. 4. Adjust the Saturation™ control for the desired amount of gain/compressed clipping. 5. Readjust the pre gain control to assure adequate drive. 6. Readjust the post gain control just below the point at which the power amp/speaker reaches the clipping point and adds its own harmonics to the pred'storted signal. This setting is readily noticeable since the additional harmonics are audible when the power amp reaches its maximum output level and will not necessarily be pleasing to the ear. SPECIAL NOTE: THE NORMAL CHANNEL CAN ONLY BE SELECTED WITH THE FOOTSWITCH ALSO. THE NORMAL CHANNEL GAIN CONTROL IS NOT AFFECTED BY THE POST GAIN AND IS THE SINGLE DETERMINING ELEMENT FOR THE LEVEL OF THE NORMAL CHANNEL WHEN THE FOOTSWITCH IS USED TO SELECT BETWEEN THE SATURATED LEAD CHANNEL AND THE CLEAN NORMAL CHANNEL, THE PULL THICK FEATURE DROPS OUT (IS DEFEATED IF IT HAS BEEN SELECTED). AS MENTIONED, THE POST CONTROL DOES NOT AFFECT THE NORMAL CHANNEL. THIS SWITCHING ARRANGEMENT ALLOWS THE PLAYER TO PRESET THE BALANCE BETWEEN THE PRE GAIN. SATURATION™, AND POST GAIN OF THE LEAD GAIN BLOCK™ FOR ANY DESIRED OVERLOAD AND LEVEL, AND SWITCH BACK TO THE NORMAL CHANNEL FOR A TOTALLY CLEAN SOUND WITHOUT INTERFERENCE OF THOSE TWO CONDITIONS. REAR PANEL BUILT UNDER U.S. PATENT NO -4.310.053 PEAVE V ELECTRONICS COOP MEPIOIAN. MS PHE OUT/ LINE FT. SW. PWR. IN OUT REMOTE SWITCH JACK:--- The remote switch jack is of the two circuit (stereo) type featuring ring-tip-sleeve construction. One circuit of this jack controls Automix'“ channel switching function enabling selection of either the lead or normal channel, while the other controls the reverberation signal. Remote switching is accomplished through the use of the supplied Automix'“ footswitch, which is conventional in function and should present no operational difficulty. Please note when plugging in the Automix'“ footswitch to be sure and insert the plug all the way ("second click") into the jack. Failure to insert the plug all the way will not allow full function of the footswitch. PREAMP OUTPUT/POWER AMP INPUT:- To allow in-line patching of battery or AC powered effects and signal processors, we have incorporated a simple out/in jack on the back panel. The out/in jack (post EQ) is a 1/4" ring/tip/sleeve configuration where the tip portion of the jack serves as the preamp output while the ring acts as the power amp input or return. The sleeve is groynd. A typical patch for this out/in jack would be to utilize a “Y” cord and connect the output portion of the "Y" to the input of the device. The return portion of the"Y” is then connected to the output of the device which will return the processed signal to the LA-400'“. LINE OUT:--- Same as preamp output except the signal has been frequency compensated to eliminate the undesirable effect of overboosting highs or lows when patching to recording or sound reinforcement consoles. LINE CORD: For your safety we have incorporated a 3-wire line (mains) cable on the bottom of the chassis with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the amplifier without proper grounding facilities, suitablegrounding adapters should be used. Much less noise and greatly reduced shock hazard exists when the unit is operated with the proper grounded receptacles.
