All tone knobs will add minimal effect when turned fully counter-clockwise. As they are turned clockwise, tone will be increased. The "low" control adds bass, the "mid" control adds mid-range and the "high" control adds high frequencies.
The high frequencies can be further extended by switching the "Bright" switch to the right. The Bright switch also affects channel "A". Adjust the "Reverb" control until the desired reverb effect is reached. With the knob turned fully counter-clockwise, no reverb effect is added. As the knob is truned clockwise, the reverb effect is increased. Switch the channel switch to channel "A", and plug the optional two-way foot switch into the "FT SW" jack on the back amplifier panel.
One of the foot switches will turn the reverb effect on or off, while the other will switch from channel "A" to channel "B". The use of a foot switch is optional, but note that the channel switch must be in the channel "A" position for the foot switch to perform the channel switching function.
If no foot switch is used, the channel switching and reverb may be operated manually. Plug the external speaker if desired into the "EXT" jack on the back amplifier panel with a speaker cord. Attach an external guitar amplifier if desired by plugging in a standard guitar cord into the "Line Out" jack. Attach external guitar effects by plugging a guitar cord into the effect devices output, into the amplifier's line in.
Plug the effect device's input into the amplifier's "Line Out" with another guitar cord. This method of connecting effects is optional, and is called an "effects loop".
MON: Use this control to adjust the level of the signal from each channel to the Monitor bus. This signal is post-level, pre-eq. The Master tone controls serve as a three-band EQ to adjust the output of the mixer to compensate for room acoustics or to fine-tune the overall sound. The Low control is useful to reduce boominess. The Mid control greatly enhances the vocals and helps control feedback.
The High control helps compensate for heavily draped, acoustically absorbent rooms, or bare walled, acoustically reflective rooms, and can be used to help control feedback. The Master Low control provides 30dB of boost or cut at 50Hz and below.
The Master Mid control provides 30dB of boost or cut at Hz. The Master High control provides 30dB of boost or cut at 10kHz and above. DSP: Use this control to select one of the sixteen on-board digital effects. These effects are described in the chart on page 4. To avoid overdriving the amplifier, this control should be set around 6 or 7 to allow sufficient headroom for peaks in the program material.
This signal is post-channel level, post-channel eq, pre-master. To avoid feedback, turn down the Tape In Level control 15 when recording. This jack is a mono input - a stereo signal will have to be mixed down to a mono signal by means of a summing device. This input is especially useful for expanding the channel count of your P. Rotate the DSP control 12 to select the desired effect.
The main DSP Ret control 13 determines the overall amount of internal effects applied to the output signal. POWER CORD: 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.

It is only after the amplifier has passed this barrage of picky people that it gets packed up and shipped out. The CA60 Acoustic Amplifier. Designed to be its best, so you can sound your best! To keep this amplifier looking its best, avoid abrasive cleansers. Wipe the cab- inet clean using a slightly dampened cloth.
