General Description
Each of the professional headsets HSC 171, HSC 271, HSD 171 and HSD 271 combines a pair of AKG Studio line headphones with a high quality dynamic or condenser microphone mounted on a flexible microphone arm. The frequency response of each microphone has been designed specifically for speech reproduction and ensures excellent audio quality. The microphones are shock mounted to minimize handling noise. The microphone arm features a microphone muting function and swivels through a 270-degree arc so you can wear the headset with the microphone on your left or right. All models are suited for any radio or TV application requiring optimum speech reproduction.
Differences between Models
Setting up
Plugging in the Connecting Cable
Insert the 6-pin mini XLR connector (1) on the connecting cable into the matching socket (2) on the headset and push home to the point that the connector will lock with an audible click.
Risk of injury!
Excessive volume can cause hearing loss! Before connecting the headset to the mixing desk, ensure that the volume is set to minimum. Only adjust the volume once you are wearing the headset.
Connecting to Audio Equipment
Connecting Cable
The microphone cable is welded to the headphone cable. If the headphone output is too far away from the microphone input, you can simply pull the microphone cable away from the headphone cable. The sliding bush lets you bundle the separated cables together again.
Putting the Headset on
The microphone arm swivels through an arc of 270 degrees, allowing you to put the headset on with the microphone sitting in front of either the left or right corner of your mouth as required by the job at hand or dictated by available space.
Switching the Microphone ON/OFF and Testing it
The microphone arm of each model features an automatic ON/MUTE switch.
- To switch the microphone ON, move the microphone arm down far enough to place the microphone in front of the corner of your mouth. The microphone will switch ON as soon as the microphone arm reaches a position lower than horizontal.
- Talk into the microphone. The flexible microphone arm allows you to adjust the microphone sound by varying the working distance. As you move the microphone away from your mouth, the bass content (and overall level) of the audio signal will decrease.
- To mute the microphone, move the microphone arm up into its detented center position. The microphone will be muted as the microphone arm reaches a position higher than horizontal.
Switching Headphones ON/OFF (HSC 271, HSD 271)
The headphones on models HSC 271 and HSD 271 will switch ON automatically as you put the headset on. When you take the headset off, the headphones will switch OFF automatically. This prevents the headphone signal from leaking into the microphone on taking the headset off.
NOTE :The on/off switch is actuated by the headband. If you hang the headset up by the headband, the headphones may switch ON.
NOTE : The headphones on models HSC 171 and HSD 171 feature no automatic on/off switch.
Operating Notes
Windscreens W 44 (HSC 171/271), W HSD (HSD 171/271)
If you use the headset in the open or need to place the microphone extremely close to your mouth, we recommend using the supplied foam windscreen.
- Slide the windscreen onto the microphone capsule.
- Pull the windscreen over the outer edge of the microphone capsule.
Replacing Ear Pads
- Pull the ear pads off the earphones.
- To attach the new ear pad(s), pull the elastic hem of each ear pad over the rim of the earphone base plate all around.
Unplugging the Connecting Cable
- Grasp the connector, depressing the locating button.
- Pull the connecting cable off the headset.
NOTE : When you connect the cable again, the connector will lock automatically.
Unwanted Noise, Feedback
To prevent the microphone from picking up unwanted signals or causing feedback (models HSC 171 and HSD 171 provide no headphone muting function), be sure to move the microphone arm into its vertical center position every time before taking the headset off. This keeps the microphone signal muted even if the microphone channel remains open.
Bass Cut Filter (HSC 171, HSC 271)
The HSC-PA phantom power adapter features a bass cut filter to suppress lowfrequency noise and reduce proximity effect. The headsets are delivered with the bass cut filter deactivated. To activate the bass cut filter:
- Disconnect the phantom power adapter from the mixer input.
- Remove the fixing screw (1) from the phantom power adapter.
- Unscrew the cable bushing (2).
- Pull the pcb out of the shell WITH EXTRA CARE.
- Remove the jumper (3) from the contact pins (4) to activate the bass cut filter.
In order not to lose the jumper (3), you can place it on a single contact pin (4).
To deactivate the bass cut filter, place the jumper (3) on the contact pins (4) in position 1 (factory default setting).
NOTE : Never place the jumper in any position other than positions 1 or 2. All other jumper positions will attenuate and distort the microphone signal.
6. Push the pcb into the shell, replace and tighten the fixing screw (1), and screw the cable bushing (2) onto the blue strain relief (5).
Deactivating the Microphone Muting Function
- Disconnect the phantom power adapter from the mixer input.
- Remove the fixing screw (1) from the phantom power adapter.
- Unscrew the cable bushing (2).
- Pull the pcb out of the shell WITH EXTRA CARE. a b Microphone muting function: ON (a) and OFF (b)
- Unsolder the green wire from the pcb and insulate the stripped end with insulating tape.
- Push the pcb into the shell, replace and tighten the fixing screw (1), and screw the cable bushing (2) onto the blue strain relief (5).
Cleaning
Cleaning Headphones, Microphone, Connecting Cable
- Disconnect the headphone and microphone cables from the mixer.
- Use a cloth moistened (not wet!) with water to clean the surfaces of the equipment.
NOTE : Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents since these may damage the enamel or plastic parts.
Windscreens W 44, W HSD
- Remove the windscreen from the microphone.
- Wash the windscreen in soap suds.
- Allow the windscreen to dry overnight.
- Slide the windscreen onto the microphone capsule.
- Pull the windscreen over the outer edge of the microphone capsule.
NOTE : To avoid damaging the windscreen fixed on the microphone, be extremely careful in removing the W HSD from the HSD 171/271 microphone!
