OVERVIEW OF DSB-3216/DSB-1632 SYSTEM

Concept

The purpose of DSB-3216/DSB-1632 system which is used for converting multi analog audio signals into digital signals and long distance transmission to another place and then restoring to analog audio signals again, is replacing the traditional analog audio stage box or cable drum.
The advantage of digitization also brings features of easy installation, low cost, convenience and easy expansion.

The old analog stage box
The old analog stage box is made up of a multi-core cable with a very large diameter, which includes multi wires (one for each channel) that convert audio signal from one place into another.
Although analog multi-core cable finishes the work, it often gives customers an experience in cumbersome, bulky, hard and signal loss over long distance.

The new digital transmission system
The fundamental benefit of digital stage box system is converting multi analog audio signals into digital signals and transmitting by a light CATE5e network cable, which eliminates the huge volume of analog multi-channel cable, also signal degradation and noise interference caused by the long distance transmission of analog audio signal, so that the system can transmit hundreds of feet or more without damage to the sound quality.

A/D – D/A convert and singnal optimization

The analog audio signal must be converted to digital signal before it transmitted by digital stage box system. Once the digital form is converted, the audio is sent to the receiving end of digital stage box unit by Ethernet cable. When get there, the signal will be converted to analog signal and connected to the audio device. For example, the process of analog mixer converting analog audio to digital data and returning again, which is called A/D and D/A transmission.
DSB-3216 and DSB-1632 units adopt very high quality 24 bit/ 96KHz A / D and D / A converters for all audio inputs and outputs to achieve the best sound quality.
In addition, DSB-3216 and DSB-1632 system provide +20dB gain preamplifier for each of 48 audio inputs so that the signal can be optimized at the source to get the higher A/D transmission quality.

USING DSB-3216/DSB-1632 SYSTEM

Rack Installation

The device is rated to operate in the range of 0”C to 40”C. When the device is installed to the EIA standard equipment rack together with other digital stage equipment or electronic equipment, the internal temperature may exceed the specified upper limit, which will cause the performance degradation and damage. Please observe the below attentions when use the EIA standard equipment rack to install the device:

When install multi digital stage boxes to the same EIA standard rack, please remain the space of IU rack between two machines. In addition, please keep the opining of the rack open or install a suitable ventilation panel to reduce the possibility of heat storage.

When install the device together with other high power equipment, such as a power amplifier that can generate a lot of heat, please reserve more than IU space between two devices. In addition, please keep the opining of the rack open or install a suitable ventilation panel to reduce the possibility of heat storage.

In order to ensure enough air flow, please keep the back of rack open and put it at least 10cm from the wall of other surfaces. If the back of the rack does not remain open, install a commercially available fan or similar ventilation option to ensure adequate airflow. If a fan assembly is installed, closing the back of the rack may provide better cooling.

AC power connection
On DSB-3216:
Connect one end of the attached AC power cord to the grounded AC power socket, connect another one to the AC IN socket for the internal power supply of DSB-3216.

On DSB-1632:
Connect one end of the attached AC power cord to the grounded AC power socket, connect another one to the AC IN socket for the internal power supply of DSB-1632.

Clamp for power cord
The casing of DSB-3216 and DSB-1632 is equipped with the clamp to prevent the connected cord from being pulled out accidently and cause power failure.

Connection and requirement of network cable

The connection of single cable requires standard Cat5e Ethernet cable with RJ45 plug and the maximum length is 100m (330 feet). The connection can be hot swappable, that is, it can be connected when the device is powered on.

Attention about Cat5e cable

• Please do not subject Cat5e cable to pressures or physical shock.
• Please do not bend Cat5e cable during 25mm.
• Please do not fasten Cat5e cable.
• Avoid placing multiple Cat5e cables in parallel for long distance.
• Avoid placing Cat5e cable around the noise source.
  (AC power cable, electric machinery, fluorescent lamp, etc.)

Dip Switch setting

Both of DSB-3216 and DSB-1632 have DIP switch which is an 8P toggle switch and sets each device how to transmit audio in the whole system. DIP switch of each device must be set correctly to ensure normal operation of the system.

Switch 1: FS Sync Mode
off°”: Clock SIave
Clock Master

Switch 1 — Master/Slave selection
When DSB connected together, there should always be a master clock source and all of other DSB should be slave clock. Under the backup mode, one DSB as Master (Switch 1 -On) and another as Slave (Switch1 -Off), if under the cascade mode, the Master on DSB at either end of the chain and all of other DSB should be subordinate.

Switch 2-4— Input cascade (use only in cascade mode, toggle down switch 5 set to ON)
These switches are used for selecting which input channels of the DSB passing up from “BACKUP” port to “MAIN” network port of next DSB.

For example, when the input cascade sets 8 (2-off, 3-off, 4-off), only the input 1-8 if the DSB pass up along the chain and all other inputs will come from inputs received through “BACKUP” network port.

Switch 5— Backup mode
Switch two communication ports of DSB to “Backup mode” and “Cascade mode”. See page 6 for details.

Switch 6-7- Output cascade (use only in cascade mode, toggle down switch 5 set to ON)
These switches are used for selecting which channels, sending out output received from the “MAIN”network port of the DSB by “BACKUP” network port.

For example, if output cascade sets 9-40 (6-on, 7-off), output 9-40 will be sent out by “BACKUP” port connected with DSB, and this DSB still has1-40 outputs.
Note: in above examples, “9-40” or “1-40” channels are only a limit channel number setting, not the channel number of this digital stage box. “9-40” pointed in the example, it’s “9-32″ in DSB-1632, “9-18” in DSB-3216.

When connecting audio input under DSB-3216 and/or DSB-1632 powered on, please turn on the corresponding interface box Lighting the indicator of [MUTE ALL OUTPUTS] button on the front panel, which can mute the sound of audio output from DSB-3216/DSB-1632 system and prevent connected speakers and other devices from damage.
Please attention, [MUTE ALL OUTPUTS] only mute outputs of DSB-3216/DSB-1632 system, not other devices. Before connecting audio outputs of DSB-3216/DSB-1632 system to audio inputs of other devices, please make sure the power supply of device is lower or closed, to prevent from damage.
