If the LEDs do not light, the sensitivity setting on the transmitter
is too low.
The red LED lighting constantly indicates overmodulation.

5. HT 60 Handheld Transmitter
The HT 60 handheld transmitter and matching microphone ele-
ments (optional) provide the same acoustic performance as the
equivalent hardwire microphone versions. The microphone ele-
ments available for the HT 60 have been specifically designed for
vocal use.
The HT 60 operates in a subband up to 4 MHz wide within the
138 MHz to 250 MHz VHF carrier frequency range. The HT 60
can be switched to a maximum of 15 different carrier frequencies
depending on local frequency allocations.
The transmitter uses a dipole antenna integrated in the body.
The controls can be protected against accidental misadjustment
collectively (2d) or individually with the supplied adjustable pro-
tective ring (2j).

LED constantly lighting brightly: batteries will be dead in
about 90 minutes.
LED illuminating brightly: audio input is overloaded.

with a colored ring from the optional Color Coding kit to iden-
tify each wireless channel by a different color.

5.2. Interchangeable Microphone Elements
The interchangeable microphone elements (2k) D 880 WL1,
D 3700 WL1, D 3800 WL1, C 5900 WL1, and C 535 WL1
are acoustically and mechanically identical to the equivalent hard-
wire versions. They feature the same transducer capsules and
mechanical construction.
Extremely high gain before feedback, optimum handling noise
rejection, ultimate protection from damage, and an integrated
wind and pop screen are only the most impressive features of
these microphones. For more details, refer to the respective AKG
brochures.

W 880 foam windscreen for D 880 WL1
W 3001 foam windscreen for D 3700 WL1 and
C 5900 WL1

6. PT 60 Bodypack Transmitter
You can use the PT 60 bodypack transmitter with both dynamic
microphones and condenser microphones operating on a supply
voltage of approx. 7 V. You may also connect an electric guitar,
electric bass, or remote keyboard.
The PT 60 operates in a subband up to 4 MHz wide of the
138 MHz to 250 MHz VHF carrier frequency range. The HT 60
can be switched to a maximum of 15 different carrier frequencies
depending on local frequency allocations.
