The HH10A consists of the handset with push-to-talk switch, equipped with a US-made coil cord and 4-pin XLR connector, and a wall-mount cradle with retaining spring-clip.
The HH10B consists of the same handset, coil cord and cradle, but the coil cord is wired to the cradle which contains a hook-switch to mute the earspeaker when the handset is “hung up”. A 10′ cable is wired to the HH10B cradle, with a 4-pin, Neutrik® XLR for connection to an intercom station. We recommend the HH10B for quiet environments where audio from the earspeaker (while the handset is in the cradle) would be a nuisance.
These heavy-duty handsets are equipped with dynamic transducers suitable for intercom use. To prevent feedback and permit high levels before feedback, the interior of the handset is partially filled with a dense mastic material, blocking internal acoustic coupling between the microphone and the earspeaker. A high-quality shielded coil cord is fitted with a Neutrik® XLR connector.
These handsets are molded from commercial telephone quality compounds. No other handset offered for intercom use provides greater resistance to physical damage. The cradle includes a spring-clip, which prevents the handset from being accidentally dislodged. The push-to-talk switch in the HH10A and the hook switch in the HH10B cradle are rated for millions of cycles.
Handsets are available in Black, and Red. All the metal mounting plates for the cradle are black.
