1,3: Input 1, Input 2. The signal output from your acoustic instrument, tape player, rhythm machine, high-Z microphone or other source may be connected to either or both of these jacks by means of a shielded signal cable. Each of the input jacks is governed by its corresponding gain con- trol (#2 for Input 1, #4 for Input 2). The signals from these two jacks are summed together after their gain stages.

2,4: Gain 1, Gain 2. Use these controls to set the input gain level for the corresponding input jack. These controls set the level of the input signal and serve as the amplifi- er’s volume controls.

5:Low. This serves as the bass control for both channels. Adjust this control to get the best sounding bass response for your instrument. Excessive boost of the low control can cause an unnatural howling (acoustic feedback from your instrument) and should be avoided.

6:Mid. This serves as the midrange control for both channels. Adjust this control to get the best projection and midrange tones for your instrument.

7:High. This serves as the treble control for both channels. Adjust this control so your high notes and harmonic overtones are lively but not overpowering.

8:Reverb Level: Use this control to adjust the amount of reverberation added to the signal. In the fully counter clockwise posi- tion, the signal is dry (no reverb added). As you rotate the control clockwise the amount of reverb increases.

9:CD Input. Use these jacks to connect the output from a CD player, tape deck, or rhythm machine to the amplifier. The CD Input jacks are post EQ and Gain, so use the level control on the CD player (etc.) to adjust the level of the signal at these jacks.

10:Headphones. Use this jack to connect headphones to the amplfier. The internal speaker is disconnected when this jack is used.

11:External Speaker. Use this jack to connect the amplifier to an external speaker. The internal speaker is disconnected when this jack is used. The impedance of the external speaker must be 4 ohms or greater. Do not attempt to use head- phones in the External Speaker jack! Permanent hearing damage could result.

12:Power Switch. (Rear panel, not shown) Use this switch to apply power to the amplifier: the amp is on when the top of the switch is depressed, off when the bot- tom of the switch is depressed. The switch illuminates when the amp is on.

13:AC Line Cord. (Rear panel, not shown) The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection.
