User manual ADVENT ADVW801

[. . . ] If you use the speaker output of an audio source to connect the transmitter, you will permanently damage the transmitter. It is only designed to work with RCA-type line/variable outputs or headphone outputs. NOTE For more information on hooking up and using the transmitter with various outputs, please see More Helpful Information beginning on page 12. Select from the following options to power the ADVW801 speaker: Make certain the batteries in the pack (I) are rechargeable. [. . . ] Fixed-level outputs from TVs are usually marked as `Constant, ' `Fixed, ' or `Select. ' If they are not marked as such, they are probably variable outputs (see About Variable-Level Outputs, page 13). Outputs from VCRs are almost always fixed. HINT When connecting to the fixed audio outputs of a VCR, remember that for the wireless system to work, the VCR must be active. In other words, turn the TV on to the channel you would normally use to watch a videotape (channel 3 or 4), turn the VCR on, then press the TV/VCR button on your VCR remote control one time to make the VCR the controlling piece of equipment. At this point, whatever channel is showing on the tuner for the VCR should be the channel playing on the TV. This configuration gives independent volume control through the TV (using the TV remote control) and at the speaker. HINT If your VCR (or other RCA-type audio source you are connecting to) is mono (a single audio output), you need to acquire another RCA "Y" Cable. It differs from the "Y" Cable Adapter included in this kit. It will have a single male RCA plug and 2 female RCA jacks. Connect the dual RCA plugs from the "Y" Cable Adapter (S) to the 2 female RCA jacks on the second "Y" cable, then connect the single male RCA plug of the second "Y" cable to the single audio output of the VCR. Is recommended when using a single speaker or if using more than one speaker in different locations. for monaural operation , set the Mono/Stereo Switch (D) to "MONO" on each speaker. B Stereo operation: You will need an additional ADVW801 speaker in order to utilize the stereo option. For stereo operation, set the Mono/Stereo Switch (D) to "L" on the speaker located to the left of the listener, and set the other speaker to the "R" position. A variable-level output, such as a headphone jack or certain RCA-type outputs, provides an audio signal to the transmitter that changes in relation to volume level on the audio source. As the volume of the audio source goes up and down, so too does the audio signal strength sent to the transmitter. This can affect the quality of sound you hear at the speaker, and may require increasing or decreasing the volume level of the audio source to achieve a suitably strong audio signal for use with the ADVW801 system. HINT Most TVs, regardless of age or price, have variable outputs. If you are unsure which, if any, of your outputs are fixed, refer to the TV instruction manual. Some TVs have outputs that can switch between variable and fixed. When given a choice, fixed is always recommended.
