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 defi- nition 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.

WARNING: DO NOT attempt to use head- phones in the Speaker jack! Permanent hearing damage could result!

8:HEADPHONE / LINE OUT jack will accept a standard headphone plug for private practicing. The speaker is auto- matically disconnected when head- phones 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.
