1. MIC
Electronically balanced XLR-type inputs for the connection of low impedance microphones,
likewise the ones that are featured in major studio and live mixing consoles. This type of input
stage provides extraordinary low noise signal conversion at an extremely low distortion rate
(typical <002%) even in the high frequency range.
Generally, any type of microphone can be connected as long as its
pin assignment is in accordance to the diagram shown aside. When
condenser microphones are connected, you have to press the
PHANTOM button which is located in the master section. The
microphone gets its operational voltage (+24Vdc) through the mixer
and you can forget about battery replacement times.
CAUTION: Make sure to always connect the microphones before turning on the phantom power
or switching the PowerMate on with activated phantom power. This is the only way to certify that
your microphones are not damaged. Also make sure to engage the stand-by button in the master
section to safe yourself and your environment from nasty power-on noise.
The connection of condenser type microphones and dynamic microphone models at the same
time is possible and should generally not lead to any problems. Before you do so, please refer to
the microphone’s manual to make sure that this kind of operation is in accordance to the
manufacturer’s guidelines.
The MIC input is laid out for levels between –60dBu … +11dBu – depending on the setting of the
corresponding gain control. Because of their low impedance design and the phantom power these
XLR-type inputs are not meant for cascading other mixing consoles or the connection of FX units,
keyboards or other electronic equipment. When connecting this kind of equipment, please use the
LINE level inputs.
2. LINE
Electronically balanced inputs for the connection of electronic instruments, such as keyboards,
drum machines, E-guitars and E-basses with an active output, as well as all other high level signal
sources, like additional mixers, FX units, CD player, etc.
The LINE input is laid out for levels between –40dBu … +30dBu. The connection of balanced or
unbalanced signal sources is established through monaural or stereo phone plugs, assigned
according to the diagram below. If the device that you want to connect has a balanced output
stage, the use of balanced cables with stereo phone plugs is preferable. This type of connection
is greatly insensitive to the induction of external noise or HF interference.
Do not connect signal sources to the MIC and the LINE inputs at the same time, since the signals
would interfere with each other, resulting in a level reduction.
One more note: Please, do not connect E-guitars or E-basses with passive, high impedance
outputs directly to one of the LINE inputs. The LINE inputs of the PowerMate – like the Line level
inputs of mixers from all other manufacturers – are meant for the connection of the relatively low
source impedance of electronic instruments or eqiupment. The reproduction of the instrument’s
original sound characteristics will be unsatisfactory – unless this effect is intended. Those
instruments should be connected using a special transformer or pre-amplifier with very high input
impedance. Musical instruments that are equipped with an active electronic output stage (battery)
can be connected without second thoughts.
When connecting signal sources, please make sure that the corresponding channel faders
or at least the master faders are at their minimal settings or the STANDBY button is engaged.
This will save you, your audience, and the equipment from extensive wear from unpleasant
knacking noise.
