INTRODUCTION

Thank you very much for expressing your confidence in our products by purchasing S-LINK8 splitter/ mixer. S-LINK8 is the good solutions for many problems of the large scale sound reinforcement systems and PA applications, and it can be used as a splitter or a mixer.
For splitter application, just apply the main signal input from the MAIN IN sockets, and select the SPLITTER mode for each individual channel, then six mono outputs can be gotten. By depressing the MAIN MIX button, two further outputs can be provided.
For mixer application, select the MIXER mode for individual channel, and feed the input signal from the mono input, then six input signals can be mixed together, and output from the MAIN OUT. By depressing the MAIN MIX button, two further inputs can be provided.
Please reserve your time to read this manual before running the unit, and you will be the real master of your S-LINK8.
The S-LINKS splitter/mixer is equipped with following features:

1. rack size.
2. SPLIT / MIX switch for each mono channel.
3.  2 input, 6+2 outputs splitter.
4. 8 Balance / Pan control for each channel.
5. Main input and output level control.
6.  MAIN LINK function allows to route the MAIN IN signal to MAIN OUT, vice versa.
7. Level meters for each stage.
8. XLR balanced connectors for 4 mono channels, and TRS type for another 2 mono channels.
9. Dual voltage unit for global operation.

CONTROL ELEMENTS

FRONT PANEL

1. MAIN INPUT LEVEL control
   This knob is used to adjust the level of the main input signal, and its adjustable range goes from ∝ to +10dB.

2. INPUT LEVEL meter
   This 6-digit meter tells you the level of the main input signal. While the Clip LED lights up, please turn down the main input signal, otherwise, the system will be distorted.

3. MAIN LINK control
   Use this switch to link the MAIN IN with the MAIN OUT.

4.  MAIN OUTPUT LEVEL control
   This knob is used to adjust the level of the main output signal, and its adjustable range goes from ∝ to +10dB.

5. OUTPUT LEVEL meter
   This 6-digit meter tells you the level of the main output signal. While the Clip LED lights up, please turn down the main signal at either each input stage or the main output stage, otherwise, the system will be distorted.

6. SPLIT/ MIX
   Use this switch to select the specific operational mode for each individual mono channel.
   For SPLITTER mode, please let the switch released, and the main input signal can then be split into each mono channel output.
   For MIXER mode, please engage this switch, and now, the mono channel input signal will be sent to the main output bus, combined with the main input signal on condition that the MAIN LINK is activated, you can get the mixed signal output from the MAIN OUT sockets.
   Further, also for the MIXER mode, you can route the mono channel input signal to the mono channel output directly.

7. LEVEL control for each channel
   This knob is used to adjust the level of each mono channel, and its adjustable range goes from ∝ to + 10dB,definitely, In SPLITTER mode, this control is used to determine the output level of each individual mono channel. While in MIXER mode, this control can be used to determine how much the mono channel input signal is sent to the main output bus and/or each individual mono channel output.

8. INPUT / OUTPUT LEVEL meter
   This 6-digit meter tells you the output level of each mono channel, while the Clip LED lights up, please turn down the level control, otherwise, this channel will be distorted.

9. BALANCE / PAN control
   Generally, the main section uses the stereo input and output, while, for each individual channel, mono application is configured. So, if the stereo main signal is split into the mono channel output, or the mono input signal is routed to the stereo main output bus, please use this knob to determine the proportion between the left and the right.

10. POWER SWITCH & POWER LED
    This switch turns on/off the unit. When the unit is powered on, the LED will light up.
    Rear Panel

11. FUSE HOLDER
    Before you attempt to connect and operate the unit, please make sure that your local voltage matches the voltage on the fuse-holder cover.
    Caution: The fuse protecting the AC supplies circuits of this unit. The fuse can only be changed by a qualified technician, in the event of a fault or changing the supply voltage. If the fuse continues to blow after replacing, discontinue use of this unit before repaired.

12. AC inlet
    This connector is meant for the connection of the supplied main cord. Do not insert power cable into the unit until the voltage has been correctly set. Do not plug power cable into AC power until voltage has been correctly set.

13. MAIN INPUTS
    These two XLR balanced connectors are used to input the main stereo signal. In SPLITTER mode, it can be split into each mono channel output.

14. MAIN OUTPUTS
    These two XLR balanced connectors are used to output the main stereo signal. By depressing the MAIN LINK, It can be linked with the MAIN IN directly.

15. INPUT for the mono channel
    For Channel |~4, use the XLR balanced connectors to input the mono signal, while, for Channel 5~6, please use the TRS type.

16. OUTPUT for the mono channel
    For Channel I~4, use the XLR balanced connectors to output the mono signal, while, for Channel 5~6, please use the TRS type.

APPLICATIONS

From the panel introduction on the chapter 3, you must have caught a clear answer to ” What is it?” in your mind as to our S-LINK8, SPLITTER / MIXER, hereafter, we will show you the further explanation on “How to use it?”, So that, you can be the real master of this unit.
How to use S-LINKS as the splitter
Sometimes, in the large scale PA / sound reinforcement systems, you may be disturbed by this kind of problems: one pre-send signal needs to be monitored by several groups, or the main mix output of the console should be transited to several power amplifiers, etc. And now, with your S-LINK8, you will get the best solution.
Connect the S-LINK8 into your systems as the demonstrated, you can split a specific main input signal into up to 6 outputs. With the MAIN LINK button depressed, 2 further outputs are added.

In this application, use the SPLIT/MIX switch to select the SPLITTER operational mode for each mono channel, apply the main signal from the MAIN IN sockets, and get the 6 outputs from the mono OUTPUT sockets of each channel. While the MAIN LINK is engaged, the MAIN OUT will also be linked with the MAIN IN signal, and two further outputs are provided.
How to use S-LINKS as the mixer
This application is widely used for the mixing of one group main stereo signal with several mono signals.

In this application, use the SPLIT/MIX switch to select the MIXER operational mode for each mono channel, input the signal from the mono INPUT of each channel, and output the main mixed signal from the MAIN OUT sockets. While the MAIN LINK is engaged, the MAIN IN will also be linked with the MAIN OUT signal, and two further input signals can be mixed with the main output signal.

INSTALLATION & CONNECTIONS

Mains Connection
This is a dual voltage unit. Please ensure that the S-LINK8 is set to the correct supply voltage before plugging the power cord into the wall outlet, use the same fuse as marked on the fuse holder at the AC power connection socket.
Do not insert power cord into the unit until voltage has been correctly set. Do not plug the power cord into AC power until voltage has been correctly set.
The mains connection of the S-LINK8 is made by using the enclosed mains cord and a standard IEC receptacle. It meets all of the international safety certification requirements.
Audio Connection
The S-LINKS presents with balanced XLR connectors and |/4″ TRS phone jack, it can be interfaced by several ways to support a variety of applications without any signal loss.
a. Wiring Configuration
Either the 1/4″ TRS (Tip-Ring-Sleeve) phone jack or the XLR servo connector can be wired in balanced and unbalanced modes, which will be determined by the actual application status, Please wire your systems as the following examples:

• For 1/4″ Phone jack
• For XLR connector

b. In Line Connection
For these applications, the S-LINK8 provides XLR connectors and 1/4″ TRS phone jack to easily interface with most professional audio devices. Follow the configuration examples below for your particular connection.

• Balanced

• Unbalanced

Rack Mounting
The most secure mounting is on a universal rack shelf available from various rack manufactures or your music dealer. The S-LINKS fits into one standard 19″ rack unit of space. Please allow at least an additional 4″ depth for the connectors on the rear panel. Be sure that there is enough air space around the unit for sufficient ventilation and please do not place the S-LINK8 on high temperature devices such as power amplifiers etc. to avoid overheating.
