Netzgerät zum Betrieb von sechs Mikrofonen N 66 E
1. Description
The C 680 BL is a cardioid condenser table microphone. Thanks to its small
dimensions, the C 680 BL can be placed so it will not distract the speaker.
When lying on a table or lectern the microphone element is very close to
a boundary. This design prevents any comb filter effects or other acoustic
interferences which would normally exist at microphone positions close to
reflecting surfaces.
The supporting surface (tabletop, lectern, etc.) limits the pickup area. In
other words, the microphone will only pick up sounds arriving from above
the table or lectern. (See the dashed lines in figs. 1 and 2.)

A transducer shock mount prevents vibrational noise such as knocking or
footsteps from being picked up.
The microphone has a low-impedance, electronically balanced output
allowing it to be powered from phantom power sources. If you use an AKG
power supply (B 18, N 62 E, or N 66 E) you may connect the C 680 BL to
balanced or unbalanced inputs. The required phantom power adapter is
integrated in the microphone case.
The C 680 BL is fitted with a fixed, 3-m (10-ft.) cable with an XLR connector.
2. Uses
2.1. Placement
Place the microphone on the conference table or lectern so that the micro-
phone will be at least 40 cm (16 in.) but no further than 1 m (40 in.) away
from the speaker's mouth.
2.2. Permanent Installation
1. Fix the supplied adhesive strips to the underside of the microphone.
2. Remove the protective films from the adhesive strips and press the
microphone against the tabletop at the desired position.
The adhesive strips are non-tainting and you can remove the micro-
phone at any time.
2.3. Repainting the C 680 BL
If you wish to blend the microphone in with the interior decoration of the
room you can repaint the C 680 BL as described below:
1. Remove the two Phillips screws from the underside of the microphone.
2. Remove the case.
