ROOTMASTER EVO II USER GUIDE Inputs There are two choices of instrument input, these are marked passive and active. The passive input is high sensitivity and high impedance to suit passive bass instruments. The active input is much lower sensitivity and impedance to accurately match the signal from active bass instruments i.e. Those with a built in battery powered pre-amp. Input control The input control sets the signal level through the preamp in conjunction with the input level vu meter.
ROOTMASTER EVO II USER GUIDE Equalisation This consists of bass, middle and treble controls with two more rotary controls placed in-between. This can be used in a number of ways: Firstly as a very simple bass, middle and treble tone control section as found on older traditional amplifiers. This is done by leaving the 340hz and 1.6Khz controls set in their centre positions and using only the bass, middle and treble controls to alter the overall tone.
ROOTMASTER EVO II USER GUIDE The compression level control adjusts the degree of compression applied to the bass signal. For this to function correctly the input level must be correctly set as described in the input control section above. When the input level is correctly set there will be hardly any difference in volume between compression in and compression out.
ROOTMASTER EVO II USER GUIDE Sub harmonics This section produces sub harmonics an octave below the notes being played. The level of these sub harmonics relative to the straight bass sound can be adjusted using the level control. This is very effective in thickening the sound and you will find in use that only a small degree of this lower octave is required to really fill out the sound and provide a character that is not possible by any other means.
ROOTMASTER EVO II USER GUIDE Effects send/return A serial effects loop is provided at a level of 0db. The effects send and return sockets for this are on the rear panel above the d.I. Socket. The effects send socket can also be used as a line out socket if required. The signal path through the preamp is only broken when a jack plug is inserted into the effects return socket. The effects send is situated after the E.Q.
ROOTMASTER EVO II USER GUIDE operate in full Bridge mode which means that both terminals are live at ALL times and must not be allowed to come into contact with the amplifier case or connected to anything other than a stand alone speaker cabinet! MAINS For use with the supplied IEC mains connector. Mains fuse is located beneath socket, please check rear of model for specific fuse ratings.
