Figure 2: Dual Receivers depicts two receiver units being mounted together in a rack.

IDR-111/iDR-222 Connections

Connect the 2 included whip antennas to Antenna A and B ports (7).
Connect the AC/DC 12VDC 1.5A power supply to DC in port (12).

Audio Output Connections:

A) Connect the BALANCED OUT A/B of each channel (8) to balanced Microphone or Line input/s with a quality balanced XLR signal cable. The XLR pinout is as follows:

1: GND (Ground)
2: HOT (+)
3: COLD (-)

B) Connect the OUTPUT A/B ports (9) to unbalanced Line input/s with a 6.35mm TS Phono jack.

C) IDR-222 Dual channel receiver only – OUTPUT MODE: The Output mode switch (10) allows users to mix the outputs of both receiver channels to OUTPUT B 6.35mm TS Phono socket. The balanced XLR microphone outputs will continue to output their discrete receiver channel.

Antenna Extension

Both the iDR-111 and iDR-222 receivers are compatible with external powered and passive antenna extension products. Antenna A&B ports are designed to power inline antenna boosters and active antenna amplifiers. Each Antenna port provides 8-12v, 300ma DC power.

Passive Antenna Extension

The included whip antennas can be extended up to 5-10 metres. It is recommended to use quality 50ohm low loss coax cable and quality TNC connectors.

Antenna extensions over 5-10 metres require active in line boosters or active amplified antennas.

Antenna Examples: The manual shows various configurations of antennas and boosters, including TNC connectors, coaxial cables, and different antenna types.

Menu Operation:

To enter menu functions, press the SET [Gear icon] ⚙️ button twice.

Pressing the SET [Gear icon] ⚙️ button once while in menu functions mode will scroll into the next menu function.

HOME Screen: The default display showing frequency and status.

AUTO SCAN: This function performs an interference-free channel search. The receiver has 8 available channel groups. The scan function automatically determines the best interference-free channel available in the immediate area. If your system is mobile, it is recommended to use the auto scan function each time you use your system in a new location.

To enter the SCAN mode, press the SET [Gear icon] ⚙️ button twice. The SCAN symbol will flash on the LCD. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to choose the desired Group (1-8). Push the SET [Gear icon] ⚙️ button once, and the receiver channel will enter automatic scanning mode. After this has completed (approx. 1-5s), the scanned frequency will flash on the LCD. Press the SET [Gear icon] ⚙️ button 5 times to reach the home screen and confirm the setting change. After auto scan, pair the receiver and transmitter.

GROUP/CHANNEL SELECTION: This mode allows users to manually set the desired group and frequency channel of the wireless system. To enter this mode from the home screen, press the SET [Gear icon] ⚙️ button twice, then one more time. The GRP number will flash. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to select the desired group (1-8 or "U" group). Push the SET [Gear icon] ⚙️ button once. The CH number will flash. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to select the desired channel number. Press the SET [Gear icon] ⚙️ button five times to return to the home screen and confirm settings. "U" Group allows users to choose a specified frequency rather than a predetermined Group and Channel frequency allocation. Refer to pages 19-20 for frequency tables. This feature is recommended only for advanced users.

IDR-111/iDR-222 Functions Operation

Power ON/OFF

Press and hold the Power button [Power button] ⏻ for 2 seconds to power on or off the unit.

Functions Menu

To enter menu functions, press the SET [Gear icon] ⚙️ button twice. Pressing the SET [Gear icon] ⚙️ button once while in menu functions mode will scroll into the next menu function.

Auto Scan

This function performs an interference-free channel search. The receiver has 8 available channel groups. The scan function automatically determines the best interference-free channel available in the immediate area. If your system is mobile, it is recommended to use the auto scan function each time you use your system in a new location.

To enter the SCAN mode, press the SET [Gear icon] ⚙️ button twice. The SCAN symbol on the LCD display should now be flashing. When the SCAN symbol is flashing, you are in SCAN mode. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to choose the desired Group (1-8). Push the SET [Gear icon] ⚙️ button once and the receiver channel will enter automatic scanning mode. After this has completed (approx. 1-5s), the scanned frequency will flash on the LCD. Press the SET [Gear icon] ⚙️ button 5 times to reach the home screen and confirm the setting change. After the auto scan function is complete, you will need to pair the receiver channel and the transmitter. See Receiver & Transmitter Pairing section.

Group/Channel Selection

This mode allows users to manually set the desired group and frequency channel of the wireless system. To enter this mode from the home screen, press the SET [Gear icon] ⚙️ button twice, then one more time. The GRP number will flash on the LCD when in Group/Channel Selection mode. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to select the desired group (1-8 or "U" group). After your selection has been made, push the SET [Gear icon] ⚙️ button once. The CH number will now flash. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to select the desired channel number. Press the SET [Gear icon] ⚙️ button five times to return to the home screen and confirm settings. "U" Group allows users to choose a specified frequency rather than a predetermined Group and Channel frequency allocation. Refer to pages 19-20 for the frequency tables. Note this feature is recommended only for advanced users.

Squelch, Equaliser, and Lock Functions

Squelch

In most cases, the default SQUELCH setting of 0.5dB is sufficient and should not be adjusted. However, if users experience RF noise interference and disruption to the audio signal, users can adjust the SQUELCH to help reduce the interference. Users can choose between 00 - 25dB of squelch. Adjusting SQUELCH would be a last resort in resolving an RF noise interference problem.

It's recommended to try a different group or channel or use the AUTO scan function to find an interference-free channel.

Equaliser

The equaliser provides users with 4 different equaliser options. The equaliser can assist in attenuating problem frequency bands should there be no other equaliser options further down the signal chain.

To enter EQUALISER mode, press the SET [Gear icon] ⚙️ button twice, then 4 more times. Once in the correct mode, the EQ symbol will flash in the LCD display. Use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to select the desired EQUALISER curve (001-004).

EQ Settings:

001 FLAT: Signal is not altered (default setting).
002 LOW CUT: Low frequency is rolled off. Use when there are plosives or low frequency rumbles.
003 HIGH BOOST: High frequency boost. Use if there are speech intelligibility problems.
004 LOW CUT & HIGH BOOST: Low frequencies are rolled off and high frequencies are boosted. Use when plosives or rumbles and speech intelligibility problems are present.

Lock

The LOCK function, when set to ON, prevents users from accessing the functions menu. The only receiver function that remains active when the LOCK is ON is the receiver output volume control.

To enable the LOCK function, press the SET [Gear icon] ⚙️ button 2 times, followed by another 5 single presses. The LCD will flash "LOC OFF". To enable the LOCK, use the UP [Up arrow] ▲ / DOWN [Down arrow] ▼ buttons to change the setting to "LOC ON". To confirm the setting and exit the functions menu, press the SET [Gear icon] ⚙️ button once.

To disable the LOCK function, press the SET [Gear icon] ⚙️ button twice. "LOC ON" will be displayed on the LCD screen. Press the DOWN [Down arrow] ▼ button to disable the lock. The LCD display will show "LOC OFF". Press the SET [Gear icon] ⚙️ button 2 times to confirm the setting and exit the functions menu.

Receiver & Transmitter Pairing and Volume Adjustment

Receiver & Transmitter Pairing

Press the SET [Gear icon] ⚙️ button once to perform transmitter and receiver infrared frequency sync and pairing. Ensure the IR sync window of your transmitter is adjacent to the IR sync window on the receiver before pressing the SET [Gear icon] ⚙️ button. Ensure both the transmitter and receiver are powered on.

When in pairing mode, the receiver will display "Ir" on the LCD display. When the pairing has been completed, the receiver will return to the home screen automatically. Your wireless system is now paired and ready for use.
