5.6.3 HSP-2A New Features and Enhancements from the HSP-2
The new HSP-2A provides these new features and enhancements:
• System operation improved for the local operator with:
o Higher power Speaker Driver circuitry
o New forward-facing speaker
o An external speaker is now included in the ACU-1000 Accessory Kit, allowing
operation at higher volume or easy installation of external speaker at operator
station.
• Handset connector pin-out changed to a more universal configuration to allow easier
interfacing of custom handsets or headsets (still works with the standard handset
supplied with the ACU-1000).
• Rear panel pin-out modified to allow the local operator’s audio and keying functions to
be remoted by cable to a 4-wire audio console or over a network through the use of the
Raytheon NXU. The pin-out changes allow these devices to be connected to P13 using
the same cables as have been created to interface them to an ACU-1000 DSP-2 module
at P1 through P12. This new pin-out is optional; all relevant connections to the HSP-2A
can be configured for same pin-out as the HSP-2, allowing full backwards
compatibility.
• Voice Prompt capacity doubled to allow future expansion.
• Signal Level LED added for easier level setting
