Z-Series Audio Optimization Guide
Follow the instructions of the
Application Note
that came with the cable. If you are missing this
for an additional copy. Included in the
Application
Note
are:
•
Configuration settings for the Radio Channel, optimized for the JPS Cable when used
with the associated radio.
Note:
The
Application Notes
were created for use with a variety of JPS gateways;
pay attention only to the configuration settings available on the Radio Channel
Settings Page in the Z-Series GUI.
•
Changes required or suggested for the radio itself, either in its configuration or
programming.
If you apply the
Channel Profile
for the radio, the profile will automatically apply the appropriate
configuration settings as a reasonable starting point.
Once appropriate configuration settings for the radio have been applied, the next step is to take
care of optimization and/or settings that should be adjusted prior to system use. Most of the
following are best accomplished using a test count from a “companion radio” that is in
communication with the donor radio cabled to the Z-Series device. A companion radio is from
the same radio system, not a cross-connected radio. Listen using a USB headset or the handset
(ACU‑Z1), or to another device cross-connected via the Z-Series device with the donor radio.

Customer-Designed Radio Cables
For customers who plan to create their own radio interface cables, JPS strongly recommends
using the Unterminated Radio Cable, JPS P/N 5961-291115. This shielded cable includes the
DB-15 end of the cable that plugs into the Z-Series device analog ports, along with the small
printed circuit board that is in other JPS cables. This circuitry has a variety of variable attenuating,
terminating, and DC-blocking components; essentially everything that JPS Systems Engineers
have deemed necessary to interface any of the several hundred types of radios they have created
custom cables for. This seven-pin cable is unterminated on the radio side, allowing the radio
specific portion of the cable to be spliced on.
The
Application Note
for this cable contains information to help in the cable design and, in
particular, explains how to determine which of the various configuration options is best (e.g. how
to decide how to choose between the COR options of VOX, VMR, or Hardware COR).
The
Application Note
information for unterminated cables is useful but will not be repeated in
this document. Application Notes for all JPS Custom Radio Cables, including the Unterminated
Radio Cable, are shipped with the cable. Additional copies may be obtained by contacting
Note
: Older versions of the Unterminated Radio Cable Application Note relate to its use with
non-Z-Series devices, such as the ACU-2000 or the NXU-2B. All relevant information applies
to Z‑Series devices.
