ZXZMCWA60AMPLIFIER

60 WATT CLASS D PLATE AMPLIFIER with W BLUETOOTH 4.0 aptX Model: MCWA60 User Manual (3) REMOTE CONTROL POWER – Toggles the power state of the amplifier from STANDBY to ON. When the unit is ON, the indicator LED will illuminate BLUE. When the unit is in STANDBY, the indicator LED will illuminate RED. (Note: Turning OFF the rear power switch will turn power completely off to the unit, disabling the remote.) VOLUME – Adjusts the volume level of the amplifier. If the source device has a volume control in itself, set the volume to full then control the volume with the MCWA60 volume control. As the volume increases or decreases the blue indicator LED will flash. When volume is at min or MAX, the blue indicator LED will not flash. MUTE – Press once to temporarily mute the amplifier. The blue indicator LED will flash slowly while the MCWA60 is muted. PLAY/PAUSE – Press once to play or pause program audio in Bluetooth mode only. PREVIOUS/SKIP – Press to move to the beginning of the current song or advance to the next song in Bluetooth mode only. AUX 1/2 – Press once to switch to the corresponding analog input on the amplifier. The blue indicator LED will flash once. OPTICAL – Press once to switch to the S/PDIF Toslink input on the amplifier. The blue indicator LED will flash once. BLUETOOTH – Press to switch to and pair with the Bluetooth input on the amplifier. The blue indicator LED will flash once. WiFi – Press once to switch to and pair with the Wi-Fi input on the amplifier. The blue indicator LED will flash once. OPERATION Once you have completed installation of the MCWA60 into your project it is best to test the system using a known operating source component connected to one of the analog inputs. The default state of the amplifier at power-ON is to enter STANDBY mode; use the remote to turn the power on and select an input to begin listening. PHYSICAL CONNECTION Connect an audio source to any of the three external inputs. Permanent connection of sources including CD/BD/DVD players, television/satellite/cable boxes, game consoles, and other sources are best supported using the OPTICAL or AUX 1 (RCA) inputs, while portable music players and PCs are best supported by the AUX 2 (3.5mm) input. WIRELESS CONNECTION – BLUETOOTH ® Bluetooth connectivity provides an easy, wireless connection for a personal audio device such as a tablet or mobile phone. The MCWA60 utilizes a Bluetooth 4.0 transceiver featuring aptX ® decoding for CD quality audio, and also supports legacy A2DP, AVRCP, HFP, and HSP Bluetooth audio profiles. This is a Class II Bluetooth receiver with a range of approximately 10 meters. To pair your device, put the phone or tablet into pairing mode. Press the Bluetooth button on the remote control. Press “scan“ on the phone or tablet and select the device labeled “DABTA“. The blue indicator LED will illuminate brightly to show pairing was successful. Note: The remote control functions PREVIOUS, SKIP, PLAY, and PAUSE are only available for use in Bluetooth mode. WIRELESS CONNECTION – Wi-Fi The Wi-Fi connection in the MCWA60 operates using the same principles as your home Wi-Fi internet connection; however, the MCWA60 does not connect to your home Wi-Fi or to the internet. Instead, it creates its own Wi-Fi network, which your source device connects to. The Wi-Fi connection provides an easy, wireless connection for a personal audio device such as a smartphone, tablet, or PC. Note: Each MCWA60 is assigned a unique Wi-Fi serial Identifier. This number can be found on the amplifier’s face (same as serial number). Open the Wi-Fi settings in your smartphone, tablet, or PC. Press the Wi-Fi button on the remote control. Scan for Wi-Fi networks and select the network labeled DAWAXXX, where “XXX“ is a unique string of numbers assigned to the Wi-Fi module. Note: In most cases your smartphone, tablet, or PC will lose internet WiFi connectivity while connected to and streaming audio to the MCWA60 amplifier. STANDBY MODE The MCWA60 will automatically switch to standby mode if no signal is sensed for 15 minutes. When a signal is sensed, the MCWA60 will “wake-up“ automatically and begin to operate. Power consumption in standby mode is less than 0.5W. ® Power: Inputs: Outputs: Frequency response: Operating power: Standby power: Bluetooth module: Bluetooth Audio Profiles: Bluetooth range: Wi-Fi: Signal to noise ratio: 2 x 30 Watts RMS (Class D) AUX 1: 2 x RCA, AUX 2: 3.5mm Stereo, S/PDIF Optical: Toslink 30" lead with 0.205" disconnects, Dual 5-way binding posts, RCA LFE Output (80 Hz Xover) 45-20,000 Hz 90 ~ 230 Vac, 50/60 Hz, 80Watts <0.5Watts V4.0 + EDR, Class II aptX, A2DP, AVRCP, HFP, and HSP 10 meters 2.4 GHz, Apple AirPlay® compatible >95dB Specificati ons and design subject to modificati on without notic e 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. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) This device may not cause harmf…

FCC ID: ZXZMCWA60 1. RF EXPOSURE EVALUATION 1.1. Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , Pout = output power to antenna in mW; G = gain of antenna in linear scale, Pi = 3.1416; R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. 1.2.
