System Power-Up; Accessing Programs - Ada MB-1 Owner's Manual

ADA MB-1 owners manual version 2

SYSTEM POWER-UP

With any audio system you should apply AC power to components in the order of signal flow.
Turn on the first device in the audio chain first and the last device in the audio chain last.
When turning your system off, use the reverse procedure!
1. Turn the MB-1 power switch to the "ON" position.
2. Turn on any effects units you have connected
3. Turn on your power amp
4. Select program number 1 on your MB-1
5. Set volume controls on MB-1, any connected effects, and power amp to the desired
playing level. In order to optimize the signal-to-noise ratio throughout your system you
should adjust the input and output level controls to get as much signal to each unit as
possible without overloading.
6. If using Bi-amp outputs adjust the crossover. Turn off the LO side of your power amp,
set crossover point for the desired amount of lows emanating from your HI speaker
cabinet, then bring the LO side of your power amp back up.
7. If your power amp's rated output is greater than your low frequency speaker handling
capability, set the Low Frequency Limiter (L.F. Limiter) on rear panel. Using the
IN/OUT switch (to A-B signal against limited signal) while playing the low string, turn
the LF. Limiter knob clock wise until the desired amount of limiting is achieved.

ACCESSING PROGRAMS

The MB-1 is shipped from the factory with 79 preset programs. Preset programs are
accessible when the PRESET button is lighted. The MB-1 has storage capacity for 256 user
programs. User programs are accessible when the INTERNAL PRGM button is lighted or
through the MIDI IN port (see MIDI Mapping section of this manual.) The MB-1's MIDI PRGM
section holds MIDI Mapping information only, no programs (preset or user) can be stored in
these registers. Please note that tone and amount of overdrive in any program will depend
on the type of pickups in your bass guitar, and any other equipment in your amplification
system.
1. To change program number within a bank press the desired ones digit button from 0
to 9.
2. To change bank and program number press the bank button. Next use the up or
down arrow buttons to select the desired bank number 0 to 25. Once the desired
bank is selected, press the desired ones digit button from 0 to 9. The MB-1 will not
change the program number until the ones digit has been pressed.
3. You may also scroll up or down through programs by pressing the up or down arrow
buttons. The MB-1 's program number range is from 1 to 256.
Note: The MIDI specification allows for 128 program change commands, thus the MIDI bus will give you access to
the first 128 programs in your MB-1. You may use either the "copy program" or "MIDI Mapping" feature (described
later in this manual) to access programs 129 thru 256.
