Press and Hold the volume knob for more than 3 Seconds to POWER the Unit ON/OFF. 2.INPUT SELECTION: Audio Input between AUX/B T/MIC 3.USB PORT: USB Card Reader&USB Charge(5V 1A) 4.DC 12V IN: 12V DC Power Supply 5.BT: Bluetooth Signal LED 6.VOL UME/ON/OFF: Master Volume Control with Power ON/OFF 7.MIC IN: 1/4 Microphone Input Connector Jack 8.AUX IN: (3.5mm)Audio Input Jack can Connect&Instantly Stream Audio From your Favorite Devices. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: – Reorient or relocate the receiving antenna. – Increase the separation between the equipment and receiver. – Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. – Consult the dealer or an experienced radio/TV technician for help. The In-Wall Amplifier has built-in Bluetooth receiver ability allowing you to wirelessly stream audio to your connected speaker system.Follow these steps to get connected: Make sure the unit is properly connected to external speakers. Make sure the unit is properly connected to a power source. 1. Before attempt ing to pair / connect, ensure the unit is in 'Bluetooth Mode'. Enter 'Bluetooth Mode' by selectng 'BT'on the unit's front panel Input Selector. 2. Press and Hold the Volume Knob for more than 3 Seconds to POWER the Unit ON/OFF. 3. Then, go to your Smart device's Bluetooth Network Settings and connect to the Wall Plate. The Network Name will appear as 'Herdio' on your device list. No password is required to connect but if you are prompted enter '0000' (4 zeroes). 4. Upon pairing, the Bluetooth LED indicator light will blink progressively quicker untl the unit successfully pairs with a compatible Bluetooth device. 5. When a successful Bluetooth connecton is established the Bluetooth L ED indicator light will shine solid and indicatng that the unit is ready to transmit audio. FCC Requirement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Line level audio is typically supplied via the front 3.5mm input jack pigtail leads located on the rear of the amplifier receiver wall plate (for-wired speaker connecton).*Please note: The unit may cease to functon, or function irregularly,if more than one audio source is connected totheunit.Ensure only a single audio source is connected at a tmeto allow for optimum performance and functonality; Can be Hard-Wired or Powered via Included Power In-Wall Audio Control Receiver with Built- in Amplifier Microphone Paging and Speaker Control Made Easy BT Wireless Music function allows you connect & Stream AUX input port plug & play Smartphones and other music devices Speaker Terminal Block, Connect up to (2) Speakers Universal Gang Box / Wall Plate Standard Size, can be Hard- Wired or Powered via Power Adapter Perfect for Home/Office Applicacations 4 32 6 5 Controller Receives & Directs Bluetooth Wireless Audio Works with All of Your Favorite Devices: (Smartphones,MP3 Players, Tablets, Laptops, Computers, etc.) Bluetooth Network Name: 'Herdio ' (No Password Required) Wireless Range: 30' Feet (10 Meters) Power Output 100 Walt Peak, 40 Watt RMS x 2 Ch.@ 4 Ohm Bluetooth Version: 5.0 Mic Input Type: Dynamic Power, Amp Type: Stereo Class-D Minimum Load Resistance: 4 Ohm T.H.D.: 0.03% (8 Ohm, 1 kHz) Power Draw: 12V 3Amps Power: DC 100-240V, 50/60Hz(12V DC Adapter) :
