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.

The degree of sub Harmonics is also dependant on the setting of the BAss control.
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. This must ONLY be used into a Balanced Microphone input, it is not intended for any other

type of connection.

This has a floating ground that is referenced to the mixing console it is plugged into and should not need ground lifting. It is also unaffected by

Phantom Powering on the Microphone input.

Make sure your XLR plug does not have the shell of the plug internally connected to signal ground or this will connect the system to chassis ground of

the ABM and may cause problems with hum.
PUsH TO MUTE

When pushed IN this button mutes the output from the preamp to the power amp, mutes the output from the d.I. socket and mutes the output from

the LINE Out socket as well. This leaves the output from the TUNER socket still available to allow muted tuning. An LEd is provided next to this switch

to indicate when the amplifier is muted. This function operates only from the front panel MUTE push switch. i.e. pressing this button mutes all sound

from the amplifier and allows a tuner connected to the TUNER socket to operate for silent tuning. Release the button and you are back in action

again.
TUNER OUT

This output socket provides a line level signal that can be used for a permanent connection to a tuner.

The signal from this socket remains when all other outputs from the amplifier are Muted allowing all sound from the amplifier to be silenced while

tuning is in progress.
LINE OUT

This output socket provides a line level/post Output Level control signal for connection to an external power amplifier driving additional speaker

cabinets.
OUTPUT LEvEL

The OUTPUT control adjusts the overall level of the amplifier. Adjust this for your preferred overall stage playing volume.
