Unpacking

Unpacking

Although your ECS-6216MS is neither complicated nor difficult to operate, we recommend you take a few
minutes to read this brief manual and familiarize yourself with the important information regarding product
features, setup and operation.

As with most electronic devices, we strongly recommend you retain the original packaging. In the unlikely event
the product must be returned for servicing, the original packaging (or reasonable equivalent) is required.

Installation

Installation

Environment

Never place this product in an environment which could alter its performance or reduce its service life. Such
environments usually include high levels of heat, dust, moisture, and vibration.

IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.

Features

- TRANSMIT THE 2 CHANNEL AND 8 CHANNEL BALANCED AUDIO SIGNAL

2 Channel Model: ITX/IRX-102, 2 channel balanced audio signal transmission
8 Channel Model: FTA/FRA/ITX/IRX-108, 8 channel balanced audio signal transmission

- THE SOLUTION OF SENDING A SOUND SOURCE IN LONG DISTANCE

Optical Cable Communication [FTA/FRA-108S] : Sending a signal in long distance (maximum 15km)
UTP Cable Communication [ITX/IRX-108(102)] : Sending a signal in long distance (maximum 150m)

- HIGH QUALITY AUDIO SIGNAL

It sends the digital signal converted to 24Bit, 48kHz to provide the high quality audio signal
(higher than S/N 90dB, less than THD 0.01%)

- AC/DC SUPPORTS

It responses to the field conditions with supporting AC and DC power input terminals

- INPUT SENSITIVITY CONTROL FUNCTION THROUGH PAD SWITCHES

If it is clipped due to high input audio signal level, push the PAD switch to decrease the input signal in 10dB

- INPUT SIGNAL DISPLAY

Detects the audio signal and clip approved to each channel and display on the front panel.

- RS-232/RS-422/CONTACT POINT DATA RECEIVING/SENDING (OPTION MODULE)

The optional module (CT-100M/CR-100M) can be installed to make a possible to receive and send a RS-232,
RS-422 and 8 channel contact point data.
