User manual TASCAM AV-452

[. . . ] D00788500B IEEE 1394 Interface Powered Mixer INSTALLATION & SUPPORT GUIDE Ü ÿ Y This appliance has a serial number located on the rear panel. Please record the model number and serial number and retain them for your records. Model number Serial number CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] This signal is not affected by the ROOM VOLUME control. FG H IJK H IR SENSOR This window is used to receive the commands from the supplied wireless remote control unit. C I AMP A and AMP B keys The AV-452 can operate in mono mode, with each amplifier driving a separate speaker, in which case, these will act as room control keys. Alternatively, it can be operated in stereo mode, in which case, these keys turn the stereo channels on and off individually. D E C ROOM VOLUME control This is used to adjust the levels from the speaker outputs as well as from the line level outputs. The indicator on this control lights when power is supplied to the AV-452. It is motorized, meaning that it will reflect changes made from the RC-452 remote control unit (E). NOTE These keys do not turn the amplifiers on and off--they simply mute the signal to the speakers. The mono/stereo setting for the line outputs is made using the dedicated switch on the rear panel e and for the speaker outputs using the DIP switches i. J PHONES level and jack Connect a standard pair of stereo headphones to this 1/4" jack. Adjust the volume with the PHONES level control (pre-ROOM CONTROL). NOTE D AUX inputs This set of three RCA jacks is used to connect a composite video signal and/or the left and right components of a stereo audio signal. E AUX selector switch This determines whether audio and video are enabled together at the AUX jacks (switch pushed in), or audio only (switch in the out position). Remove the headphones from the jack when turning the AV-452 on or off, to avoid possible damage from "thumps". K RGB 2 input Connect one end of a VGA standard 15-pin D-sub (analog) cable to this connector and the other end to a personal computer. The signal is passed through to the RGB 2 THRU connector on the rear panel. NOTE F CASCADE key When this key is active (lit), the input to the CASCADE inputs (rear panel) is fed to the stereo bus (pre-ROOM VOLUME). A rear panel switch determines whether this input replaces the input signals or is summed with them (see ("CASCADE (switch 2)" on page 17). G INTERCOM key When this key is lit, the signal received at the INTERCOM connection on the The AV-452 is not provided with an "RGB 1" input or output. This numbering system refers to any projector or video display unit connected to the AV-452. TASCAM AV-452 Installation & Support Guide 9 4 ­ Remote control unit features The RC-452 remote control unit is designed for control of not only the AV-452, but up to four additional connected units (marked as CASSETTE, VCR, CDRW and DVD). A total of 36 keys in total can be programmed (as described later in this section). When using the RC-452 with the AV-452 or any other unit, make sure: · There is a clear unobstructed path between the remote control unit and the remote sensor on the unit being controlled. · The remote control unit is located within 5 m (15 ft. ) of the unit being controlled, and is pointing at approximately right angles (±30°) to the front panel. The RC-452 should be maintained in the same way as a consumer control unit. When changing the batteries: should note that if the batteries are removed for an extended period of time, data loss will occur, and the codes must then be re-learned. 1 2 3 4 5 6 7 8 9 A B C D E 1 SET key and indicator Used when learning commands for other units (as described below) · Always make sure that both batteries are replaced together. · Do not mix batteries of different types. · Always make sure that the batteries are located with the correct polarity (the positive terminals of the batteries should match the + markings inside the battery compartment, and the negative terminals should match the ­ markings). · If you are not going to use the remote control unit for an extended period of time, remove the batteries. Old batteries can leak, casing damage to the remote control unit. · Always dispose of used batteries in the way recommended by your local garbage disposal authorities. NOTE 2 [TV/PROJECTOR power keys] One programmable key (ON) is used to put the TV or projector on, and the other (OFF/STD-BY) is used to put it into standby or off mode. 3 AMP A and AMB B keys These keys duplicate the function of the AMP keys on the AV-452 (I). 4 AV selector keys These keys duplicate the function of the audio and video keys on the AV-452 (A and B). 5 MUTE keys These keys duplicate the function of the microphone MUTE keys on the AV-452 (1). 6 [CASSETTE keys] Use these programmable keys to control a cassette deck (pre-programmed for the TASCAM CC-222 when the unit is shipped). The CASSETTE and CD-RW keys of the RC-452 are programmed at the factory to control the TASCAM CC222 unit. However, they may be programmed to control other units. The names of these keys and other keys which may be programmed are enclosed [in brackets] in the list below. [. . . ] When this switch is in the OFF position, the GATE THRESH trimmer pot d has no effect. AV DUCKER (switch 6) This switch enables or disables the AV ducking circuit. When this switch is in the OFF position, neither of the AV DUCKER trimmer pots: the RATIO or THRESH c controls, has any effect. TASCAM AV-452 Installation & Support Guide 17 7 ­ External control The AV-452 can be controlled from other units in two ways. The first is a serial protocol, as used by many AV controller vendors. This allows a number of AV-452 units to be controlled from a personal computer, as well as by these dedicated controllers. [. . . ]
