Introduction
The Messenger is a high fidelity instrument preamplifier, perfect for the studio, live performances, or practicing at home. The preamp offers a wide array of features in a compact, easy to use format.
 
Up to 15 dB of clean gain
Shelving bass and treble EQ
Variable low pass and high pass filters
Middle EQ with adjustable frequency
Headphone output
Auxilliary stereo input with level control
Unbalanced line out and balanced XLR out with ground lift
Foot switch function can be assigned to either bypass the EQ or mute the signal 
 
Input
The 1/4" unbalanced input can accept instrument level signals from various sources, such as electric bass, guitar, acoustic guitar, and keys/synth. If you wish to use a line level signal, it is recommended to use a higher supply voltage (up to 24V) to provide adequate headroom. The input impedance is 1MΩ. 
 
Low Noise Gain
The Volume knob provides clean, low noise gain to the instrument input, ranging from -∞ to +15 dB. Set the Volume knob at noon for unity gain.
 
Equalizer (EQ)
The EQ is a boost/cut type, providing +/-15 dB of range, and is flat with the knobs at noon. The EQ is applied to the instrument input signal only. The auxilliary input is unaffected.
The Bass is a shelving type EQ, affecting frequencies below 80Hz
The Treble is a shelving type EQ, affecting frequencies above 3kHz
The Middle EQ affects the frequency set by the associated Middle Freq knob
The Low Pass and High Pass filters are 12dB per octave active filters with a smooth response in the pass band
 
Auxilliary Input
The 1/4" auxilliary input accepts stereo signals from your music player. If you wish to use an audio source that only has an 1/8" output (such as a smart phone), you will need a separate 1/8" to 1/4" cable, like the Hosa CMS105.
 
The Aux knob controls the volume of auxilliary input, and varies from -∞ dB to unity gain. When setting the volume of the auxilliary signal, start with the knob at minimum and gradually turn up the volume. The auxilliary signal is only present in the headphone output, and is not affected by the EQ or foot switch.
 
Outputs
The 1/4" line out is an unbalanced instrument level output, capable of driving other pedals, amplifiers, or preamps
The 1/4" headphone stereo output can drive headphones or in-ear monitors. The auxilliary signal is sent to the headphone output only
The balanced out can drive long XLR cable lengths, and includes a ground lift switch. The Messenger will safely block phantom power applied from a mixing board. The balanced out is not attenuated. Be sure to have the receiving device set to line level sensitivity (not mic level).
The Volume and EQ settings affect the instrument signal in the line out, headphones out, and balanced out
 
Foot Switch
The foot switch bypasses the EQ section. One use of this feature is to compare your affected and unaffected signals, helping you to determine if you have made the right EQ changes. Another use is to switch in an EQ setting for a part of a song, such as for a solo, or a song that requires a different tone than normal.
 
The foot switch function can be assigned to mute your signal instead of bypassing the EQ. To assign the function, set the internal toggle switch to the down position. If you wish to assign the function back to EQ bypass, set the internal toggle switch to the up position.
 
Power Requirement
The Messenger requires a DC supply (not included). The supply must be at least 9V, but no greater than 24V. The Messenger draws 25mA. The connector must be a boss style, 2.1mm barrel, center negative polarity. A 24 volt power supply may be purchased separately.
 
The Messenger does not accept a battery. Phantom power will not power the pedal, but no damage will occur if applied.
 
Dimensions
The Messenger is 4.8" wide x 4" long.
