Powering the Transmitter Connect the small, round plug from the transmitter AC power adaptor to the transmitter power input jack and plug the other end of the adaptor into any standard 120V AC wall outlet. Page 8 Of 15 Rev 00 Press the ON/OFF button of the transmitter. The Red LED on the power light should be ON. II. Connecting to an Audio Source Connect the audio cable to the LINE IN jack of the transmitter and plug the other end to audio source (e.g. LINE OUT of DVD player). Turn the LINE IN selection switch to LINE IN. Page 9 Of 15 Rev 00 The Audio/Video Switch is for latency select. Usually set at Audio for music listening. III. Connecting to Speakers Page 10 Of 15 Rev 00 Insert bare wire part of speaker cables of to corresponding Left and Right Channel Output of the Wireless Amplifier. IV. Powering the Wireless Amplifier i. Turn the volume by rotating the volume control at the back of the unit to middle. ii. Insert the small, round plug from Wireless Amplifier AC power adaptor into the power input jack iii. Plug the other end of the AC power adaptor into any standard 120V AC wall outlet. Note: Be sure to use the AC power adaptors rated 15V DC 1600mA or listed in page 6, 7 and 8. 1. After powering up the Wireless Amplifier, the power/RSSI indicator will start blinking in green and orange color and searching for transmitter. Page 11 Of 15 Rev 00 2. If transmitter is found and connected, the power/RSSI indicator will turn green. 3. Turn volume up at the back and you should hear sound coming from the speakers. Adjust the volume as desired. V. Audio Muting When audio source is cut off for 3 minutes, the Wireless Amplifier will be muted. But if audio signal resumes, the muting will be disabled and speaker will be ON again. VI. Active/Passive Receivers The 2.4GHz system can support infinite no. of receivers (wireless amplifiers, speakers or headphones). However, the no. of receivers increase, the performance will be downgraded, i.e. transmission range will be reduced. The first two receivers paired with the transmitter are called “Active” receiver/speaker. The receivers paired later than the “Active” receiver/speakers are called “Passive” receiver/speaker. For multi-receiver system, the “Active” Page 12 Of 15 Rev 00 receivers/speakers can maintain its performance and are independent with the no. of receivers in the system. If one “Active” receiver/speaker is powered off, the other “Passive” receivers/speakers cannot be jumped into Active Mode automatically. They have to be powered off first and then power up again to make it “Active”. Page 13 Of 15 Rev 00 Page 14 Of 15 Rev 00 The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
