User manual GALLIEN-KRUEGER MICRO LEAD

[. . . ] Operating Instructions Micro Lead Series A Word from Bob Gallien and Rich Krueger We want to personally introduce you to our labor of love: The Microamplifier Lead Series. They symbolize our continuing effort to make the musician's life easier and more fulfilling. Everything, from the input stage to the speaker outputs, has been redesigned and refined for one purpose : the ultimate guitar sound. After getting accustomed to the fact that this little package puts out an unbelievable amount of power, the first thing you'll notice is how quiet the amp is. [. . . ] This will damage the amplifier and void your warranty, so please be careful in setting up your speaker configurations!· · · · · · · Auto Amplifier Shutdown : To protect against failure, the ML/S and ML/E heads and combos are equipped with an Auto Shutdown feature that is enabled when the Speaker Outputs are overloaded or when the temperature of the unit exceeds safe operation. The power dissipation in the outputs is actually computed to determine if it is within safe operating conditions and automatically shutdown when limits are exceeded. When shutdown occurs, the unit will appear to be on and all functions and LED's will work; however, there will be no power output to speakers. To reset the amplifier, turn the power switch off, wait 3 seconds, remove or lower the input signal, and turn the amplifier back on. If you experience more shutdowns, even after correcting the cause of the initial shutdown, check all speakers and cables. If further action is necessary, please call your local GK Service Center. Rear Panel Features (18) Right/Stereo Line Out Provides a line level signal (post Output Level)for interfacing with outboard power amplifiers: Right Line Out for mono internal power units. (see Sample Hookups) . . . . on Mono Power Units: Plugging into the Right Line Out splits the preamp signal; "left" going to the internal 130 watt power amplifier and "right" going to the Right Line Out. By connecting this line out signal to an external power amplifier (in this case the GK ML/P), you have created a 130 watt per channel stereo guitar system. A slight volume loss in the internal channel is normal. (continues on the next page) (20) Internal Speaker On/Off Switch (Combos only) Turns the internal speaker(s) on and off. In the "off" position, full power can be taken from the internal power amplifier(s) to drive external speakers(see Minimum External Speaker Impedances above). (21) AC Receptacle and Fuse Holder This combination grounded AC jack and fuse holder is designed to accept a detachable power cord. If a replacement is needed, it should be UL rated at 10amps/125vac or 5amps/240vac. Never operate this amplifier with any other than the recommended fuse type : 5mm ´ 20mm, slow blow, 250V with ampere ratings as follows: Line Voltage 117VAC 220VAC 100VAC Fuse Rating 2. 5 Amps 2. 5 Amps 3 Amps Fuse# T2. 5A · 250V T2. 5A · 250V T3. 0 · 250V The fuse can be easily removed with a screwdriver as shown on the right. A spare fuse is located in a sliding compartment. Do not remove it!!!! (22) Power Switch Turns the unit on (1) and off(0). Unplug the unit if it is not being used for an extended period. ML/E ONLY : (23) Compressor Switch Turns the Clean Channel's Compressor on and off. The compressor boosts low level signals while decreasing high level signals to add sustain. It is preset to an overall general purpose 2:1 compression ratio, ideal for most applications. The Compressor can be turned on and off with the RFG4 Foot Controller only when this switch is in the "on" position and the RFG4 is plugged in. (24) Stereo Reverb Control Controls the amount of delayed signal mixed with the main signal from the internal reverb. Clockwise rotation of this control increases the amount of reverberation effect in the ignal. (25) Stereo Chorus On/Off Indicator LED When lit, the Stereo Chorus effect is activated. (26) Stereo Chorus On/Off Switch Turns the Stereo Chorus on and off.
