FRONT PANEL � MASTER SECTION 1: INPUT jack accepts a standard 1/4� phone plug and is suitable for any low to line level signal source. 2: VOLUME controls the overall sound level. EQUALIZATION AND OUTPUT: 3: LOW adjusts the bass range in the amplifier: turning the control to the left reduces the low frequency output; turning it to the right increases the low frequency output. The Low control allows a total range of 15dB of boost or cut at 60Hz. You may want to �roll off� the bass at higher volumes. 4: LOW MID tends to add a �thicker� or �fatter� characteristic to the sound. The Low Mid control allows a total range of 18dB of boost or cut at 630Hz. 5: HIGH MID provides clarity and definition to your string attack. The High Mid control allows a total range of 19dB of boost or cut at 2kHz. 6: HIGH controls the upper range of frequencies and adds brightness and �click.� The High control allows a total range of 27dB of boost or cut at 10kHz. 7: EXTERNAL SPEAKER jack is for connecting an extension speaker to the unit. 8: HEADPHONE / LINE OUT jack will accept a standard headphone plug for private practicing. The speaker is automatically disconnected when headphones are plugged in here. A line level signal can also be obtained from this jack for recording, etc. 9: POWER �ON� INDICATOR LED will be lit when the unit is turned on. 10: POWER switch turns AC power on or off.
