INPUT MONO
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 extraordi- nary low noise signal conversion at an extremely low distor- tion 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. Connecting condenser microphones is no problem.
The microphone gets its operational power supply (+24V)
through the mixer and you can forget about battery replacement times.
The connection of condenser type microphones and dynamic microphone models at the same time is possible and does generally not lead to any trouble. Before you do so, please refer to the owner’s manual of the microphone. 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 utilize the LINE level inputs.
2. LINE
Electronically balanced inputs for the connection of electronic instruments, such as key- boards, drum computers, 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 sig- nal sources is established through monaural or stereo phone plugs, assigned according to the diagram below. If the device that you are going to connect provides a balanced output stage, using balanced cables with stereo phone plugs is certainly preferable. This type of connection is greatly insensitive to the induction of external noise or HF interference.
Do not connect signal sources to a channel’s MIC and the LINE inputs at the same time, since the signals cause mutual interference, resulting in a level reduction.
One more note: If possible, please, do not connect E-guitars or E-basses with passive, high impedance outputs directly to one of the mixing console’s LINE inputs. The LINE inputs of the PowerMate - like the Line level inputs of mixers from other manufacturers - are me- ant for the connection of relatively low source impedance as they are found with electronic instruments. The reproduction of the instrument’s original sound characteristics will be un- satisfactory - 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.
