4.2. C 400 BL-1
The C 400 BL-1 has been designed specifically for use
with video cameras, telephones, dictaphones, or simi-
lar equipment with a built-in power supply for condens-
er microphones (fig. 12). The 5-foot (1,5-m) micro-
phone cable is terminated with a threaded 1/8“ mono
jack plug which you can connect directly to the micro-
phone input. (Refer to the appropriate section of your
equipment manual.)
Alternatively, you can power the C 400 BL-1 with an
optional B 29 battery supply from AKG. The B 29 also
lets you mix two microphones down to one common
input for saving mixer inputs. For details refer to the
B 29 manual.
4. Powering
Both the C 400 BL and C 400 BL-1 are condenser
microphones and therefore need a power supply.
4.1. C 400 BL
The C 400 BL has been designed for phantom power-
ing to DIN 45596 (12 V, 24 V, or 48 V). The 7-foot
(2-m) microphone cable is terminated with a phantom
power adapter which you can connect directly to a
balanced XLR microphone input.
If your mixer or tape recorder provides phantom pow-
er, switch the phantom power on, referring to the ap-
propriate section of your equipment manual.
If your mixer or tape recorder has no phantom power,
insert an external phantom power supply between the
microphone and mixer input.
