1. Introduction

Congratulations on purchasing the DCD-24 Word Clock Distributor. The DCD-24 is
designed to distribute and generate extremely low-jitter Word Clock.
The DCD-24 can generate any standard rate, up to 192KHz, with any of the pull
coefficients. It can also generate non standard rates using the VSO.
The DCD-24 can be used as a stand-alone master clock generator or genlocked to
an external reference. As with the DCD-8, the generated frequency does not need
to be a multiple of the reference frequency. For example, the DCD-24 can generate
44.1KHz referenced to a 96KHz source.

2. Installation

2.1. UNPACKING
When unpacking the DCD-24 the following items should be in the shipping
carton:
• DCD-24 unit
• Universal Power Supply (12VDC @ 16w)
• IEC power cable
• Owner's Manual & Registration card
2.2. INSTALLING THE DCD-24
The DCD-24 is designed to be mounted in a standard 19" rack. It requires
1U in height. Ideally, it should be located near your AD/DA and in the same
rack.
Usual precautions should be respected when wiring the DCD-24: use high
quality cables with good shield to guarantee a good signal transmission.
Keep your cables as short as possible.
Devices connected to the DCD-24's WC outputs need to be terminated. If no
termination is provided on the device, use a BNC-T with a 75Ω termination. If
multiple devices are connected to a single DCD-24 WC output, only the last
device in the chain should be terminated. However, to preserve the integrity
of the transmission line, it is recommended that you do not daisy-chain word
clock outputs as it can significantly degrade signal quality.

3. I/O's Description and Cable Requirements

3.1 POWER
The DCD-24 requires 12VDC @ 18W. Acceptable range is 12VDC +/-15%.
The external supply provided with the DCD-24 accepts 100 to 240 VAC input
at 50 - 60 Hz so it is suitable for use anywhere in the world.
Optionally, a second power supply can be connected to Power Input B for
redundancy. To order a second power supply contact your dealer.
☛ Insert the 4 pin plug into the rear panel jack and secure by screwing the
ring. Plug the supply into the wall using the standard IEC cable supplied.
