Amplifier use AMA-1 mk11
(Quick start on Page 4)
Before switching on your amplifier, ensure all volume controls are at minimum and
connect all inputs and outputs.
Your instrument or microphone should be connected to input 1 or 2, each have the
same facilities so you may chose either and achieve the full use of the amplifier.
All the connectors are on the left of the amplifier, and all the controls on the right.
Input 1 & 2 connectors:
These XLR/Jack input connectors will
accept either 3pin male XLR connectors or
1/4" (6.35mm) jack plugs. The input
sensitivity is the same whichever
connector is used. Phantom power may be
applied to the XLR connector, no effect will
be noticed if the phantom power button is
on when you use the 1/4" jack connection.
Gain, Level and Phantom Power:
This control section changes the level of
the input signal taken from your
instrument or microphone.
The Input Clip LEDs show when there is a
good signal level and when the level is too
high. With a low level input signal these
LEDS may not illuminate. With a good
signal level they will flash or remain constant Green. When the signal is too high the
LEDS will remain constant Red. When the LEDS are mostly Green and only
occasionally flash Red, then the signal level is at its optimum level. To set these input
the signal to the amplifier at the highest level that is likely to be used. This means if
you are playing an instrument, play it loudly, if singing then sing loudly. Adjust the
Green Gain knob until the LEDs are Green with only occasional Red flashes. Do not be
afraid to use the green control as maximum, it is designed to operate at that level.
Whilst performing this setting point, the White Level knobs will do nothing. To get
the most out of your amplifier it is best to use the Gain control at as high a level as
possible whilst still maintaining the sound you want.
Pressing the black Phantom buttons, applies 12v phantom to Channel 1 or 2, the LED
will illuminate Red when Phantom is present. Phantom Power only appears on XLR
connections.
The level knobs allow the user to balance the two channels and should be used, if
possible, above 4 or 5.
