MAkING CONNECTIONS
Before making connections, ensure all level controls are turned
down to zero (fully counter-clockwise), all switches are set in the out
position and PA system speakers turned off. This prevents power
turn-on transients from damaging more sensitive components such as
tweeters. Plug the mPress power supply in. There is no power switch.
Once connected, the mPress will spring to life. To verify power is being
received, depress the MIC-1 ON switch to illuminate the LED.
Locking XLR power supply included.
Test the microphone level with headphones
before sending the signal to the mains.

Connect your first microphone to the MIC-1 Input. You can use the front
panel XLR or the one on the rear panel.
Do not use front and rear
inputs at once.
They are simply wired in parallel for convenience. If
phantom power is needed, activate the 48V power switch using a small
screwdriver. This switch is recessed to avoid accidentally engaging or
disengaging phantom power. Connect a pair of headphones to the
mPress and set the headphone level control half-way (12 o’clock) to
start. Slowly increase the MIC-1 Input level until you see the input
meter LED illuminate. Test the level for maximum input by speaking
loudly until the RED LED illuminates. Then back down the level for
extra headroom. Adjust the headphone level as you go along to suit.
MIC 2 input can be used independently on a second source in a
conference or town-hall meeting arrangement. In this case, connect
using the same method as outlined above. When both mic inputs are
engaged, they are summed after the limiter section to a mono output
that will be present at each of the GALLERY OUTPUTS, the MAIN
OUTPUTS, and in the HEADPHONES.
Once your mic levels are set, engage the MAIN OUT ON switch to
activate the sends to the PA system and slowly raise the MAIN OUT
LEVEL control until the desired output is achieved.
The mPress ships with two XLR barrel adapters with -30dB pads
to take the line level outputs of a mixing console down to mic level,
allowing you to use the balanced XLR mic inputs.
Push IN to activate the
48V phantom power for
condensor microphones.
