10- Line input with RCA connectors, with input impedance of 22Ω for the
connection of high output signal types, such as iPods - computers -
keyboards.
11- output with RCA connectors for connections to external devices such as
recorders - computers - iPods, etc..
12- STEREO IN: Volume control for each channel (10) to be sent to the
MASTER volume (26).
13 - 14- Tone control input (10), treble (13), bass (14) with a variation of + -
15db. Placing the controls in the middle do not give magnification or
attenuation of the corresponding frequencies.
15- STEREO OUT: control output volume (11). This control is independent
from the MASTER volume (26)
16- amplified output headphone jack stereo connector, pre master
independent of the MASTER volume (26). (The headphone amplifier is
class A).
17- PHONES: volume control for headphone output (16). This control is
independent from the MASTER volume (26).
18- DIRECT OUT: electronically balanced output with XLR connector, POST
EQ for connection to other sound systems.
19- LINE OUT: unbalanced output with JACK POST EQ connector for
external amplification systems where the cable to connect them are not
long.

20- VOL. LINE OUT: level control of LINE OUT (19) independent from the
MASTER volume (26).
21- EFF. RET.: Volume that controls the amount of the DSP to send to
MASTER (26).
22- EFF. (LED AND SWITCH): the SWITCH allows you to slide the flashes of
the led 1-8 so that you can hear all the effects and stop at the most suitable
for that type of instrument.
23- OFF-ON RESONANCE: When pressing the button the led turns on, and
the resonant circuit starts working. This circuit is used to make sure that
when you plug in an acoustic guitar at a high volume the guitar does not go
into resonance.
24- RESONANCE: p otentiometer which (once the button is pushed), by
turning moves the NOTCH FILTER from a frequency of 100 Hz to a
frequency of 250Hz. The attenuation of NOTCH FILTER is 12db.
25- PH (LED AND SWITCH): The switch allows you to enable or disable the
PH for powering condenser microphones. When the PH is active, the LED
is on.
26- MASTER: general volume of the amplifier. When this knob is set to 0, any
instrument is connected does not come out.
27- PW: power indicator.
