16 DR-800 Digital Voice WAV Player
The DR-800 plays prerecorded WAV files stored on a standard SD memory card. The Digital Voice
Player will support ninety-nine WAV files of any length limited only by the size of the SD memory card
used.
Digital Voice WAV Player Installation
Mount the DR-800 on the under side of the cover using the supplied drill template and hardware.
Connect the ribbon cable to the P8 header on the CAT-800 board. The CAT-800 controller requires
firmware Version 1.02 or greater.
Turn on the power and check the red LED on the DR-800 lights indicating the SD card has initialized.
The SD memory card supplied with the DR-800 has nine prerecorded tracks for test purposes.
Track [T01.wav] is a sample repeater ID.
Track [T02.wav] is a 320 second recording of the NOAA weather transmitter located in Miami Florida.
Track [T03.wav] is a 12 second sample-meeting announcement.
Track [T04.wav] is an aircraft cabin chime suitable to use as a unique courtesy tone.
Track [T05.wav] is a Westminster chime suitable for used in the grandfather clock message.
Track [T06.wav] is an Alarm Warning Tone
Track [T07.wav] is a Tornado Warning
Track [T08.wav] is a string of DTMF Tones
Track [T09.wav] is a 10 second 1000 Hz test tone.
Track [T10.wav] is a 10 second 400 Hz test tone.
Digital Voice WAV Player Adjustment
If you have access to a deviation meter, key-up and enter [72501] to
play track #01. Adjust R7 on the DR-800 board for 3 KHz deviation at
the transmitter output. If a deviation meter is not available, key-up
and enter [72502] to play track #02. Adjust R7 so the track’s audio
level is the same as the repeaters receive audio.
Turn the power off and remove the SD memory card. Insert the card
in your computer’s memory slot. Transfer your recorded WAV files to
the card. Reinsert the card into the Digital WAV Player. Turn the
power on. Verify the red LED on the DR-800 board is lit. Fold the
ribbon cable back on its self and close the cover.
WAV File Preparations
You can use any of the popular WAV file generator programs. The only
requirement is that the file must be recorded in monaural with a
sampling rate of 8000, 11025 or 16000 and be formatted in WAV
(Microsoft) signed 16-bit PCM. There is very little difference in audio
quality at the various sampling rates. A WAV file recorded with a 16000-sample rate uses
approximately 2,000 KB per minute. This means the 8GB SD card supplied with the DR-800 can hold
recordings in excess of sixty minutes.
WAV File Name Requirement
As you record the WAV files their filename must correspond to their track number. For example: The
filen
ame for track #1 must be “T01.wav” and the filename for track #30 must be “T30.wav”.
NOTE: If you do not use all ninety-nine tracks it is suggested that you save the default tracks for
future testing and evaluation.
Digital Audio WAV Track as Repeater ID
Track [T01] is assigned exclusively as the repeater’s ID track message. Record Your ID on Track 01.
Program Event macro 17 with the following: [*17171* 6611 3300 6610]. The repeater will ID using
Track 01. If a repeater user keys-up when the track is playing the track will stop and the ID will
switch to CW.
