| Installing the RCA WSP155 900MHz Wireless Speaker System
- Plug the supplied AC power adapter into an electrical outlet near your audio source. Make sure it is the one for the transmitter (“DC 12.5V”)—the two for the speakers are marked accordingly.
- Connect the plug end of the power adapter to the DC jack located on the back of the transmitter (see diagram). The green LED indicator light on the top panel will glow when an active audio source is detected. The LED indicates the unit is transmitting which indicates the unit is receiving power.
- Locate the audio input cord on the back of the transmitter. The 3.5 mm standard plug can be used to fit most headphone output jacks in audio equipment. If you are connecting to the audio output jacks from a TV, amplifier, etc. then plug the audio input cord into the “Y” adapter that is provided to adapt standard RCA type audio plugs for the audio source.
- Turn on the audio source. The CHANNEL SELECTION CONTROL is located on the back of the transmitter. Select the desired channel by using the switch on the back of the transmitter. This channel can later be switched to achieve optimal audio reception. This speaker system has automatic ON/OFF control that automatically turns the transmitter on if there is an audio signal detected and the green LED light on the top of the transmitter will glow. Once the audio source is switched off, the ON/OFF control will turn off power and stop transmitting to the speakers and the green LED will be off (after a 4 minutes timeout period).
This system also features ALC (Automatic Level Controls). ALC prevents audible distortion of the input signal and maintains an optimal level of the input signal. The ALC prevents overloads that can occur from suddenly raising input signal.
- You may use either the AC adapter or 4-“D” size alkaline batteries (sold separately) to power the speaker. Make sure the “Volume On/Off Control” knob is turned to the off position.
- If you are using the AC adapter, locate the ones marked “For Speaker” on the label and plug them into an electrical outlet located near the location for each speaker. Then, insert the plug end into the DC INPUT jack located on the back of the speaker. If you are using batteries, remove the BATTERY DOOR and insert 4-“D” size alkaline batteries in each speaker making sure to insert the batteries in the correct polarity as indicated. Once the batteries are inserted correctly, replace the battery door by first inserting the 2 tabs into the back cabinet slots then closing it until it snaps in place at the bottom tab. Check to make sure it is closed securely before moving the speakers. You can expect the batteries to last approximately 15 hours total when the speakers are played at a mid-volume level. IMPORTANT: Do not mix batteries with different chemistry types (for example, a zinc battery with an alkaline battery). Do not mix new and used batteries. Do not leave batteries installed in the product when not in use for long periods.
- Position the speakers about 20 feet away from the transmitter to perform this tuning setup. Turn on the speakers using the VOLUME control and set them to the desired listening level. If you hear static or noise and the signal is not clear change the CHANNEL SELECTION CONTROL on the back of the transmitter and then try to tune the speakers using the AUTO SCAN button on each one.
