regardless of the device’s connection status. If the indicator comes on, you can check if the device’s status
is at PRT or MUTE from the OLED panel at the front of the PC program.

● If the PRT indicator is on:

The PRT indicator comes on if power is not being supplied to the device correctly, or a problem has
occurred with the wire connections/speaker connections, or each channel of the equipment has been
overloaded. When the indicator comes on, remove all cables connected to the device, wait until the
FAN stops moving (approximately 15 seconds), then restart the device in accordance with standard
booting protocols.
If the device operates normally when power is connected, it is highly likely that an issue has occurred

connected to the device, and reconnect if necessary. If the PRT/MUTE indicator remains when power

s re-connected and the OLED panel at the front or the window program indicates PRT, it may mean

i
the device is broken. In such case, inspect your device at the Inter-M branch you purchased your
device or visit our customer service center.

※ Caution: When installing the system, ensure that the total impedance of the speaker does not fall below

STEREO MODE

The device produces the input signal from each channel independently. It produces the input signal from
CH1 through CH1, and the input signal from CH2 through CH2. In STEREO mode, you can control the
volume of each channel independently.

BRIDGED MODE

You can use this mode when you want to tie CH1 and CH2 together to produce a larger sound than you can
in STEREO mode. If you connect the speaker in BRIDGED mode, as shown above, you can double the input
signal of CH1.

※ Caution

1. In BRIDGED mode, please input through CH1 or CH3 only. The device can double the input signal

2. When you connect the speaker in BRIDGED mode, use PIN 1(+) and PIN 2(+) from the 4 Pole Speaker

The above screen appears once the power is connected, booting is complete, and the power switch has
been turned ON. It displays the volume and IP address for each channel, and you can check the connection
status of your PC.

- Initial Settings

- Volume of each channel: You can control between -50.0dB and 00.0dB

- IP Address: 192.168.1.99

- Description of Button Functions

①CH/MUTE BUTTON: Switches the OLED panel from the initial screen to the Volume Set screen where you

can control the volume of a particular CH.

②SELECT/ENTER(ENCODER): If you rotate the dial left/right, you can scroll up/down or left/right and

change the values on the screen. If you press the dial down, you can select the corresponding function.
The system will redirect you to the sub-level.

③MENU BUTTON: Switches the OLED panel from the initial screen to the Menu screen where you can

configure the settings.

④ESC BUTTON: The screen goes back to its previous state.

※ Precautions

TEMP LIMIT

If the temperature of the device exceeds 50℃, the system immediately operates the FAN. If the
temperature of the device exceeds 70℃, the system goes into TEMP LIMIT mode and reduces its ouput
level to 1/16W. You can check the TEMP LIMIT status from the OLED panel at the front or the PC
program.
Once the device goes into TEMP LIMIT mode, reduce the input level, check whether the FAN inside the
device is operational, and inspect the air vents to cool the device down sufficiently. Please be aware that
if the temperature of the device continues to rise, the device will go into PRT status and power itself down.
The device manages its TEMP LIMIT status separately for different CH groups i.e. it separates the CH1/2
group from the CH3/4 group.

OUTPUT SHORT

When a malfunction occurs to the device due to an output speakon wire short, a speaker connection
error (connected at 2Ω or below), or an overload in 2Ω/4Ω BRIDGE mode, the system goes into
OUTPUT SHORT mode. You can check the OUTPUT SHORT status from the OLED panel at the front or the
PC program.
In OUTPUT SHORT mode, the device will not produce sound unless power is turned ON/OFF using the
power switch at the front or the AC Powercon.. (LATCH protection circuit activated) Once the device goes
into OUTPUT SHORT mode, check the input level of the device, the speaker connection (check speaker
impedance), and the speakon cable connection (whether or not a short has occurred). Unlike TEMP
LIMIT, the device manages its OUTPUT SHORT status separately for each CH.
