User manual TASCAM PA-30

[. . . ] While the PA-30 is almost indestructible, it has been engineered to be easy to service. Like all TASCAM professional products, it is backed by a worldwide network of TASCAM dealers and TEAC authorized TASCAM service centers. This manual presents a detailed description of the unit's features, along with basic connection instructions and specifications. Please take a few moments to study it before connecting and operating your PA-30 Power Amplifier.

[. . . ] BTL Indicator The orange LED BTL indicator will light whenever the MODE switch (on rear panel) is in the 'BTL (MONO)' position. 2. PROTECTION Indicator The red LED Protection indicator remains off whenever the PA-30 is turned on and is operating normally. If an overload, short circuit, DC offset or other problem triggers the internal electronic protection circuitry, the unit shuts down and the Protection indicator lights. Once the PA-30 is turned off and the fault condition is cleared, the Protection circuit will automatically reset, and normal operation can be resumed (provided that the fault has not damaged the unit). 4. INPUT LEVEL Control A single rotary variable attenuator sets the input sensitivity of the PA-30 Amplifier. The degree of attenuation varies from zero loss (maximum sensitivity) at the 'MAX' position to infinite loss at the 'MIN' position. 5. PHONES Jack This Tip/Ring/Sleeve 1/4" phone jack accommodates 8 ohms or higher impedance stereo headphones. TASCAM PA-30 5 Features Figure 4. INPUTS (A & B, XLR & RCA Type) Two input connectors are provided for each channel: one RCA (phono) jack and one XLR-type female connector. Either connector may be used on a given channel, but both connectors for a single channel should not be used simultaneously. Both inputs present a high impedance, and cause no appreciable loading to source outputs. Input sensitivity is ­10 dBV (0. 3 volt RMS) at the RCA inputs, and +1. 3 dBu (0. 9 volt RMS) at the XLR inputs, for rated output (with Input Level control at maximum). Pin assignments are as follows: XLR-type Pin I = common Pin 2= 'high'(+) Pin 3= 'Iow'(­) RCA-type Shell= common Tip = 'high'(+) If the MODE switch is not correctly set, damage to the loudspeakers or to the PA-30 may result. For a complete explanation of use of the MODE switch, consult the section on 'BTL Operation' on page 9 of this manual. 8. SPEAKERS (A & B) A pair of color-coded locking terminals is provided for output connections to each channel of the PA-30. The minimum allowable load impedance for each output is 8 ohms. The actual output connection configuration will vary depending upon the mode of operation selected and the number and type of loudspeakers used. Please refer to the sections on 'BTL Operation' and 'Output Connections' before making connections to the PA-30 outputs. Virtually any line-level source may be connected to these inputs. (Refer to the 'Connection and Installation' section for further details. ) 9. Mains Power Cord The inlet for AC power to the PA-30 is a two-prong ungrounded plug (rear panel mounted). MODE switch A single two-position slide switch (on rear panel) selects either monophonic BTL (Balanced Transformerless, also known as 'bridged', with switch set to BTL) or stereo operation (with switch set to STEREO). 6 TASCAM PA-30 120V Connection and Installation Input Connections Before making connections to the PA-30 signal inputs, find the nominal output level of your signal source (this information is usually given in the Specifications section of the instruction manual). Equipment operating at ­10 dBV should be connected to the RCA (phono) inputs, while +4 dBm equipment will operate best if connected to the XLR-type inputs. (Low-level signal such as an electric guitar or phonograph cartridge will require an external preamplifier. ) From Source Equipment Components that operate at ­10 dBV normally feature either RCA or 1/4-inch phone output connectors, presenting an unbalanced (two-connection) drive. Standard connecting cables and adapters may be used with such equipment. [. . . ] Power Requimments: 120/230 volts, 50/60 Hz, AC switchable; 8 Watts at idle, 130 Watts at rated output.
