Audio Output Connection. Fig. 3

Connection Methods:

• Channel Signal Output: Connect each channel's balanced output (XLR) to a mixer or amplifier's MIC IN jack using an XLR Male to XLR Male microphone cable.
• XLR Output Wiring Diagram (Fig. 3): Pin 1: GND, Pin 2: HOT+, Pin 3: COLD-.
• Mixed Audio Signals: Connect mixed audio signals from CH1-CH4 via the receiver's balanced output XLR connector (10) to a mixer or amplifier's balanced input jack. Alternatively, connect from the receiver's unbalanced output 6.3 mm connector (11 or 16) to a mixer or amplifier's LINE IN jack.
• Using XLR to 6.3 mm Jack Cable: For LINE IN connection on a mixer/amplifier, use an XLR to 6.3 mm jack cable and set the Volume Level Switch (9) to +10dB.
• Unbalanced Output Connection: For short distances or when using "PHONE" type connectors, use a 6.3 mm jack to 6.3 mm jack audio cable to connect the unbalanced output jack (16) to the LINE IN jack of a mixer/amplifier.
• Volume Level Settings: When connecting to a MIC IN jack, set the Volume Switch (9) to 0dB. For LINE IN connection, set to +16dB for balanced output (XLR) and +10dB for unbalanced output (6.3mm). If the amplifier's output volume is distorted, switch to -6dB.

Antenna Connection: Antenna connectors provide 8-volt DC bias for MIPRO antenna boosters. If the antenna cable exceeds 10 meters, an antenna booster is recommended for optimal reception.

III. Receiver Operation

1. Before powering on the receiver, ensure all transmitters are off and the mixer/amplifier volume is minimized. The receiver is operating normally when turned on and the VFD screen glows.
2. The RF meter glows when the transmitter is powered on. The AF audio meter glows according to signal strength. If the RF or AF meter does not glow, adjustment or repair may be needed.
3. Microphone volume is adjusted at the amplifier or mixer; no adjustment is needed at the receiver.

IV. Tips for Receiver Installation

1. Receivers can be installed in an EIA standard 19-inch rack case (Fig. 4).
2. Rackmount kits are available as an option (Fig. 5).
3. For improved reception, an optional rear-to-front antenna cable installation through rackmount screw holes is recommended (Fig. 6).
4. To improve reception range, install the receiver at least 1 meter above the ground and away from EMI/RFI "noise" sources. Place the transmitter at least 1 meter away from the receiving antenna (Fig. 7).
5. Proper antenna installation enhances receiver efficiency. Minimize the distance between the receiving antenna and transmitter for best reception quality.
6. Use MIPRO's antennas for proper receiving sensitivity.
7. Antenna connectors provide 8V DC bias output. Avoid short circuits.
8. Install MIPRO's directional antennas and boosters if extended reception distance is required.
9. Use the antenna distributor in multi-channel wireless systems to simplify antenna installation and improve receiving efficiency.
10. For multiple compatible systems, select MIPRO's factory preset interference-free channels within the same group for optimum performance.
11. Rackmount two units side-by-side:
• (A) Remove top and bottom screws (Fig. 8).
• (B) Screw top, bottom, and back plates to join two receivers (Fig. 9).
• (C) Rackmount with an optional rack-mount kit (Fig. 10).

Use the Rotary Knob (5) to adjust the Group number. Press the knob to select, turn right to increase, turn left to decrease. Press again to save.

(B) CHANNEL Setting (Fig. 14)

Use the Rotary Knob (5) to select and save channels. Press to select, turn right to increase, turn left to decrease. Press again to save. The last group allows selection and saving of up to 16 frequencies. Frequency can be adjusted in 1MHz and 25kHz steps.

(C) PC ADDRESS Setting (Fig. 15)

The receiver has an ACT-BUS interface for PC remote-control. Addresses (01-64) must be pre-programmed and unique to avoid conflicts. Use the Rotary Knob (5) to adjust the address number.

(D) SQUELCH Setting (Fig. 16)

Use the Rotary Knob (5) to adjust the squelch level. Turning right increases the squelch level (decreases sensitivity), turning left decreases the squelch level (increases sensitivity). Press to save.

(E) Lock & Unlock Receiver Panel (Fig. 17, Fig. 18)

Press the Channel Selection Button (3) to set panel lock status. Press and hold the Rotary Knob (5) for 3 seconds to lock or unlock the panel. A lock icon [Lock Icon] appears when locked.

(F) ACT Sync Setting (Fig. 19)

Press the ACT button to synchronize frequency between transmitter and receiver. The LCD displays "SYNC" and then "FAILED" if synchronization fails. Ensure the transmitter's ACT IR port is aligned with the receiver's within 30 cm. Successful sync displays the group and channel on both units.

4. Unchangeable Setting

• (A) Battery Meter (Fig. 20): Displays remaining battery life percentage. Replace batteries when indicators fall to 10% (1 indicator remaining). Refer to the transmitter's user guide for detailed battery life information.
• (B) Error Message: "ERR01" indicates an internal data error.

VI. Notes
