Amphony 1800 Wireless Speaker Kit Installation Guide

Amphony 1800 Wireless Speaker Kit

Unpacking : Check that this package contains:
One iFinity Digital Audio transmitter, two iFinity Digital Audio amplifiers – Model 1800, one small and two large AC adapters (wallwarts), four short speaker cables, one short audio cable.

Connecting the transmitter

The transmitter connects either to a standard line-out audio interface via the supplied short audio cable or to an amplified speaker output via the supplied short speaker cables. Also an iPod can be docked into the iPod cradle. Note: Newer-generation iPods and iPhones can be docked using a Lightning-to-30- pin adapter. If the transmitter is connected via speaker cables, observe the polarity of the cable connection to ensure that the transmitter will be fed with a correct polarity signal. If one of the cables is switched (reversed), one speaker will receive an opposite polarity signal which will degrade sound performance. The transmitter can also be connected to other audio outputs such as RCA outputs by using an appropriate adapter. Connect the supplied small AC adapter’s barrel-shaped plug into the DC jack labelled “7.5 V“ at the rear of the transmitter, and then plug the AC adapter into a standard outlet. We recommend the use of a surge protector to protect the transmitter from power surges.

Using the transmitter speaker-level audio input:

Connecting the wireless amplifiers

• Connect the DC power input of the amplifier with the supplied large 36 V AC adapter (wallwart). ATTENTION: Connect the amplifier to the AC adapter
• BEFORE connecting the AC adapter to the power outlet to avoid sparks due to rush-in current.
• Each amplifier connects to regular passive loudspeakers via the supplied speaker cable. Observe the correct polarity when connecting the speakers.
• Connect the left speaker to the amplifier marked “LEFT”. Connect the right speaker to the amplifier marked “RIGHT”.
• Never short circuit any amplifier audio output since this may damage the amplifier. A clicking noise may be generated during amplifier power up. Therefore, it is recommended to connect power to the amplifier prior to connecting the speakers.

Placing the transmitter and wireless amplifiers
For best reception, we recommend that each amplifier be placed within the line of sight from the transmitter. If possible, each amplifier should be placed right side up with its front toward the transmitter. The transmitter should be placed at an elevation such that there are no obstacles between the transmitter and amplifiers (line of sight) in an area where there will be the least amount of traffic. We suggest that you place the transmitter on top of your audio source. Example 1 below shows the optimum placement of the transmitter and an amplifier. If no line of sight is possible, place the transmitter and amplifiers such that there is the minimum possible number of walls and obstacles between the transmitter and each amplifier. The amplifiers can also be placed as shown in example 2. In this case, no lineof-sight connection exists and the operating range is reduced. You can mount the amplifiers vertically by using the 2 screw openings at the bottom of each amplifier. If the amplifiers are mounted vertically, the operating range is reduced compared to mounting the amplifiers right side up. We suggest that you experiment with placement in order to find the best location for the transmitter and amplifiers.

Note : This product will not work properly from within an enclosed metal cabinet.

Step4 Pairing the transmitter and wireless amplifiers
In order for the transmitter to transmit to wireless amplifiers, they need to be paired. To pair the transmitter and a wireless device, push the transmitter pairing button. The network status light will start flashing quickly. Then push the pairing button of the located at the bottom of the wireless amplifiers (accessible through the mounting holes) within 5 minutes. You can transmit to up to 4 wireless devices from one transmitter. The transmitter can also stream to iFinity wireless speakers and iFinity wireless receivers. Pair each wireless amplifier as shown above.

Description of the network status light

• Flashing Slowly: No paired wireless device detected
• Flashing Quickly : Pairing Mode
• Always On: Audio is being streamed

Operating the amplifiers

As soon the amplifiers are paired with the transmitter and the transmitter is on, the amplifiers will output the amplified audio signal to the speaker outputs. The amplfier marked “LEFT” will output the left audio channel and the amplifier marked “RIGHT” will output the right channel. You can change the audio level by adjusting each amplifier volume control. In order to achieve maximum transmission quality, the transmitter level control should be set to match the audio level of your audio source as follows:

• Set the amplifier volume control to a low level to prevent clipping inside the amplifiers.
• Set your audio source to output the maximum audio level that you will encounter during normal operation such that both the left and right channel are balanced.
• Turn the transmitter level control knob to the position that yields maximum audio loudness to the speakers without any clipping (distortion). If the transmitter level is set too low, the dynamics of the transmission are not fully used. If the level is set too high, audio clipping (distortion) will occur inside the transmitter.
• Turn each amplifier volume control to a setting that yields the desired volume from the speakers such that the volume at both speakers is balanced.

Troubleshooting
