sonorisation system for accordion, here set up on a diatonic button accordian B. Loffet ADVANTAGES

The AKG mike used to pick-up the melody side is conceived for the accordion, the sonority of the instrument is truly respected and "mise en valeur". The preamplifier is designed especially for these microphones.

The left hand is as well picked-up as the right hand, which is rarely seen with a stand microphone. The basses of the instrumentist is emphasized. Finally one will hear that you play basses ! The bass preamplifier is also especially designed for these microphones.

The noises of valves and mechanical noises are strongly attenuated by the choice, the placing and the suspension of the microphones.

The separate outputs guarantee a faithful sound and an optimum mixing. Seen by the table of mixing, they are two static mikes with high level of output. The outputs are symmetrized.

The high level output and the placing choice of the microphoness decrease the risks of feedback due to the Larsen effect. (the Larsen effect is this unpleasant whistle, which is in fact an acoustic loop between a microphone and a loudspeaker, amplifying the sound of this microphone.)

The connectors (XLR) are highly reliable, durable and do not produce parasites and cracks when moving.

Total immunity against parasites, "cracks" and the "rummle" thanks to the symmetrization of all the lines.



TECHNICAL DATA

Mikes :

Right hand : micro external AKG, on removable, discrete flexible device.

Left hand : high quality measurement mikes, " back électret " technology, flexible suspension

Outputs :

Symmetrical low impedance (600 Ohms) on XLR 5 connector and supplied multipair cable (diagram) with output on 2 XLR 3 (1 ground, 2 +, 3 -) called IEC wiring.

Right hand and left hand separate

High level of output.

Power supply : Needs phantom power from 18 to 48 V (the Phantom power is a system present on the professional mixing tables, which supplys power to the external apparatuses by the audio cables.)
Internal refillable 9 volts battery with integrated charger.

Independent Phantom power case as an option

The electronic PCB manages the level, the symmetrization of the outputs, consumption, the phantom power, the supply regulation, the battery charger and the microphones supply. The module is switched on by connecting the XLR 5 output connector. option: outputs on two XLR 3 connectors (compatible with mike cables, if there is room enough on the accordion).
