AH300 FRONT PANEL
1. CH1/CH2 MIC INPUT Balanced XLR input for low impedance microphone signals (200-600 Ohms).
2. CH1 LINE INPUT Unbalanced Jack input socket for connection of all line level signals (keyboard, signal processor, sample, drum machine, etc.). Note that the Mic
and Line inputs may be used simultaneously, although it may be difficult to balance input levels, depending on your source.
3. LEVEL Adjusts the channel level, enabling the user to balance levels across channels.
4. FX SEND Controls the amount of signal sent to the inbuilt digital FX unit.
5. & 6. HI & LO Active treble and bass controls, allowing ±15dB cut or boost.
7. CH2 LINE/INSTRUMENT INPUT Unbalanced high impedance input for connection of high impedance devices such as electric guitars/basses, or regular line
devices. This channel features +6dB gain compared to the other line inputs, so take care if connecting a line level device here.
8. CH3/CH4 STEREO LINE INPUT 2 x Unbalanced Jack sockets for connection of a stereo line signal. Sockets may also be used to connect a single mono source,
or two individual sources. When connecting independent sources, use the output controls on your device to adjust the balance between the two signals.
9. CH5 STEREO PHONO LINE INPUT Stereo RCA sockets for connection of line level devices

12. FX LEVEL Controls the mix level of the inbuilt FX. Use the FX to add atmosphere to your sound, or to create interesting effects. See table (page 15).
13. GRAPHIC EQ A 5-Band graphic equaliser to fine tune your sound and help eliminate feedback issues. This is applied to the master mix. EQ is best used subtly.
Cutting or boosting all bands, or using extreme settings can reduce clarity and dynamics.
14. POWER LED Indicates that the unit is powered on.
15. AUX INPUT 3.5mm Stereo Jack for connection of an auxiliary source such as an MP3 player. This input is controlled by the master volume control. The graphic
equaliser has no effect on the Aux input.
16. ALT OUT Balanced line output for recording or connection to the PA. This output is not affected by the equaliser or master volume. The Aux input does not
appear on this output. This allows you to record your performance without the presence of a backing track.
17. PHONES VOLUME Controls the volume level of the headphones. This allows you to monitor with or without the loudspeaker.
18. PHONES Stereo headphone socket.
19. MASTER VOLUME Sets the overall output level of the amplifier.
20. LINE OUT Post-master volume output. You can use this socket to drive another amplifier while controlling the overall level from one unit.
FX SELECT Selects any one of 16 preset effect programs. See table (page 15).
FX SWITCH Pressing this switch in engages the internal digital effects unit. This switch must be engaged to use the remote footswitch. The LED will light when FX is active.
