ABM EVO III Design Philosophy This is a NO COMPROMISE design using the best parts available wherever possible. • Some examples of this are as follows: • Gold plated jack sockets for reliability and long life. • Powerful output stages for extra headroom (rated in English RMS real power and not MUSIC or PEAK power as these can claim to be 2 or 3 times the actual real power of the amplifier).
Front Panel Facilities INPUTS - There is a single instrument input provided linked to a PASSIVE/ACTIVE selector switch. The Passive input (switch out) is high sensitivity and also high impedance to suit the output from PASSIVE basses. The Active input (switch in) is low sensitivity and lower impedance to suit the output from ACTIVE basses. INPUT CONTROL - The INPUT control sets the signal level through the preamp in conjunction with the INPUT LEVEL VU Meter.
Front Panel Facilities (continued) DIRECT INJECT (D.I.) - A balanced D.I. is provided on a latching XLR socket. This has a push button placed below it that allows the user to choose either a Pre E.Q. signal (button pushed IN) or a Post E.Q. Post Sub and effects signal (button OUT). The output signal from this XLR socket is set to a level and impedance suitable for connecting directly into the Microphone input of a mixing desk for either Direct Injection into the PA system or for recording.
Rear Panel Facilities EVOIII 500 I o EVOIII 900 EVOIII Rackmount Preamp LINE INPUT - The rear panel has a Line Input socket for connection of other signal sources into the system. This can be used for plugging a CD, Tape or MP3 player into the amplifier for practising, rehearsing or for connection of a second pre-amp into the system. EFFECTS SEND / RETURN - A serial effects loop is provided at a level of 0dB.
