Specifications: Bluetooth profiles: 5.1, A2DP, AVRCP Supported Bluetooth Codecs: SBC, AAC, aptX, aptX LL, aptX HD Balanced Audio Output: XLR male Audio Inputs: Bluetooth and USB-C XLR Output level: 1.23V RMS Bluetooth range: Up to 32.8 feet (10 m) Frequency band: 2402 to 2480MHz USB charging: Type-C 5V, 500mA USB-C Charging Port PAIR LED Status: Flash blue and red alternately: in pairing mode Cyan = aptX Green = aptX HD Blue = SBC Pink = AAC TWS LED Status: Solid blue: successful TWS connection Flashing blue: TWS connecting Turn ON / OFF TWS: Hold the “TWS” button for about 3s to force the device to enter / exit the TWS pairing mode (Turn ON blafili XLR First) Reconnect: short press “TWS” when out of connection CHG LED Status: Solid red: charging Off: fully charged Red LED flashes 5 times every minute: battery low needs to recharged again PAIR LED PAIR, Power ON/OFF button TWS LED TWS button Battery Status LED XLR Output Rechargeable battery: Built-in lithium-ion 320mAh Battery life: Up to 10 hours Recharging time: Up to 2 hours A2DP frequency response: 20 Hz - 20 kHz (ref 1 kHz, ± 3 dB) USB DAC resolution: 16-bit / 48 kHz Dimensions: 117 x 30 x 25 mm Weight: 0.09 lbs / 40 g Controls: Turn blafili XLR ON / OFF: Hold the “PAIR” button for about 3s to Turn ON / OFF the device Play / Pause: short press “PAIR” when playing music Reconnect: short press “PAIR” when out of connection White = aptX LL Bluetooth Pairing a Single blafili XLR: 1. Power on your Bluetooth device. 2. Press and hold the PAIR button for 3 seconds on blafili XLR. The PAIR LED will flash blue and red alternately while blafili XLR is in pairing mode (Time out: 2 minutes). Stereo-Linking TWO blafili XLR Units: 1. Follow steps 1-5 in the Bluetooth Pairing a Single blafili XLR section to connect the 1st unit of blafili XLR, and follow step 2 to turn on the 2nd blafili XLR. 2. Press and hold the TWS button for 3 seconds on the first blafili XLR. Then press and hold the TWS button for 3 seconds on the secondary blafili XLR. 3. Both blue TWS LEDs will blink while each blafili XLR searches for the other (Time out: 2 minutes). 4. When they are successfully linked, the blue TWS LEDs on both units will be lit solid. 3. Navigate to your Bluetooth device’s setup screen, find “blafili XLR” and click/connect. 4. When paired successfully, the PAIR LED will illuminate solid color: Note: Double press PAIR button to enter pairing mode again. Note: Before pairing, turn off Wi-Fi on your device and stop any audio playback. Note: If your Bluetooth device prompts for a pairing code, enter “0000”. 5. Adjust the volume on your Bluetooth device or connected mixer/powered speaker. To erase previous pairing settings, first turn on blafili XLR, then hold the “PAIR” and “TWS” buttons until all the THREE lights(PAIR: White & TWS: Blue & CHG: Red) are lit indicating that pairing settings have been erased. You can now pair to a new device. Note: When two units are stereo-linked and connected to Bluetooth, the primary unit will send the left channel audio, and the secondary unit will send the right channel audio. If it is wrong, just exchange the position of the two blafili XLR units on your mixer.

FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in KDB 447498 D01 General RF Exposure Guidance v06 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. Report No.: LGT24H123HA01 Page 7 of 9 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] • [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,where f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
