Hughes & Kettner Acoustic Guitar Amplifier manual Connections and Control Features

2.0 CONNECTIONS AND CONTROL FEATURES

INSTRUMENT INPUT WARM: This instrument input has high input sensitivity. Connect acoustic guitars with low output levels- instruments without on-board preamplifiers-here.

INSTRUMENT INPUT BRIGHT: This instrument input has low input sensitivity. Connect acoustic guitars with high output levels - instruments with on-board preamplifiers - here.

VOLUME: Controls the volume level of the instrument channel. If the signal is saturated (the guitar sounds distorted), your instrument has too high an output level and must be plugged into INSTRUMENT INPUT BRIGHT. If the signal is much too soft, your instrument's output level is too low. Plug the guitar into the WARM input.

CONTOUR: This knob shapes the basic tonal characteristics of the guitar's sound. This feature offers a wide range of subtle tonal variations-from soft, creamy tone heavy on the mids to crystal-clear sound with punchy bottom end and sparkling highs.

SERIAL FX LOOP: Serial insert to the instrument channel. It is designed to take external effects devices. In the signal chain, it is located pre-voicing section, which means that the tone controls influence the sound of the effects signal.

SEND: Connect this jack to the input jack of your effects device.

-10 dB Switch: This damping switch lowers the level of the instrument signal. Press this button when you're using devices

designed to take instrument input levels, as is the case with most stomp boxes.

RETURN: Connect this jack to the output of your effects device.

BASS: Controls the level of bass frequencies in the instrument signal.

MID FREQ: Use this knob to select the mid-range frequencies that you want to affect (boost or cut).

MID LEVEL: Determines to which extent the mid-range frequencies that you selected are cut or boosted.

TREBLE: This control adjusts the high frequencies of the instrument signal.

MIC VOLUME: Determines the input volume of the microphone channel.

REVERB: Controls the intensity of the on-board reverb effect. The reverb level is automatically adjusted so that the instrument signal gets more reverb than the microphone signal.

FX-MIX: Adjusts the amount of effect signal to be mixed in with the original signal. Hard left = dry (original signal only)/ hard right = wet (effects signal only).

MASTER VOL: Controls the overall output of the MONTANA.

PARALLEL FX-LOOP: The parallel effects loop influences the instrument channel and the microphone channel equally. The effects signal is mixed in with the original signal in the preamp stage.
