User manual TAG MCLAREN AUDIO PA10

[. . . ] By using a separate `box' for each part of your audio system you minimise the interference normally caused by the close proximity of components. Separating the preamplifier from the power amplifier also means that the power supply is not shared, so power fluctuations 04 The theoretically-ideal preamplifier reproduces sound perfectly over an infinite range of frequencies ­ starting from well below the audible range and extending far The circuits in the PA10 (a Class A amplifier) are `no-compromise' designs using high-quality, high-stability, components to send a smooth, clean signal 05 welcome to your power amplifier for excellent sound quality. To achieve fidelity at low frequencies the PA10 uses capacitors to block the unacceptable Direct Current (DC) but let the sound signals through. TAG McLaren Audio has expended many man-years of design effort on the special circuit design which, without compromising sound quality, accommodates the high values of capacitance that must be used. versatile output separate Class A amplifier to supply headphones. The PA10 gives you versatility without compromising hi-performance, hi-fidelity. Two sets of output sockets are provided for connection to power amplifiers. The outputs are buffered and have low impedance so they can supply more than one power amplifier (e. g. [. . . ] The instruction manual for your cartridge will tell you which type you have. connecting a turntable If you have a moving coil cartridge, connect it to the PHONO inputs labelled mc on the back panel of your PA10 and press in the input selector button next to the connectors(2). If you have a moving magnet cartridge, connect it to the inputs marked mm and ensure the selector button (3) is released. Please see page 16 for recommendations about grounding your cartridge and turntable. PHONO mm mm left mc RECORD cd tuner tape 1 tape 2 tape 3 phono right mc ground 1. 2. The TAPE out 1, out 2 and out 3 output sockets are connected together internally A loop is created if a tape recorder output and input are both connected to your PA10 and the same tape recorder is selected as the record input. To avoid this possibility, we recommend that you select the input for recording before you set your recorder to record 1. 3. Record Industry Association of America The input selector button is a latching switch. One press will hold it in, the next will release it Some moving coil cartridges have such a high output that you will get better results by using the mm input with the input selector set to mm 12 13 volume control headphones The VOLUME and MUTE controls alter the signal level of OUTPUT 1, 2 and the headphone socket. They do not affect the output of the record sockets (TAPE out 1, 2 and 3). headphone connection Turn the VOLUME down before you connect your headphones. Insert the headphone plug into the 1/ (6. 3 mm) stereo jack 4" socket on the front panel of your PA10(1). volume Turn the VOLUME knob clockwise to increase volume and anticlockwise to decrease volume. If you use your PA10 in conjunction with a TAG McLaren F3 Series amplifier (such as our 60P, 100P or a pair of 125Ms), and supply it with an input with a peak level of 2 V rms (the typical output from a CD player), your PA10 gives its full rated output with the VOLUME knob in the middle of its travel. Turning the knob past this point may distort the sound and could damage your loudspeakers. VOLUME loudspeaker muting You can only use your PA10 to listen to headphones when the preamplifier output is switched off using the MUTE button, as described on page 14. There is no output to the headphone socket when the MUTE button is out. MUTE mute Press the MUTE button on the front panel of your PA10 to switch off OUTPUT 1 and 2. The PA10 also mutes automatically for a short time to allow all the voltages to stabilize whenever you change an INPUT(2). MUTE 1. Muting protects your PA10, your amplifier and your loudspeakers and prevents unpleasant switching noises upsetting your listening experience 1. OUTPUT 1 and 2 are connected together in parallel 3. A `monobloc' is a single-channel or mono power amplifier You can use OUTPUT 2 instead of OUTPUT 1. They are the same electrically This diagram, and those that follow, are for illustrative purposes only; they are not to scale and do not show all connections 18 19 connecting power amplifiers connecting power amplifiers using mono amplifiers Instead of one stereo power amplifier, you may prefer to use two monobloc amplifiers (such as our 125M) in conjunction with your PA10. Connect OUTPUT 1 left of the PA10 to the audio input of one of the monoblocs and OUTPUT 1 right to the audio input of the other monobloc. Connect each monobloc to a loudspeaker(1). OUTPUT 1 2 bi-amping left right With many high-quality loudspeakers, you can make separate connections to the high- and low-frequency drivers(1). If your loudspeaker allows it, you can improve the sound further by using separate amplifiers for high and low frequencies. This may allow you to increase the volume without distorting the sound. As each amplifier is operating in a smaller bandwidth, intermodulation distortion may also be reduced. out This diagram shows a PA10 connected to two right speaker hf left speaker hf TAG McLaren Audio monobloc 125M power amplifiers lf lf in out in out 1.

If your PA10 is still under guarantee, please refer to the guarantee card which gives you details on how to claim against the guarantee. Please keep the original packaging and use it whenever your PA10 is transported. cleaning In order to maintain the appearance of your PA10, you can clean it as follows: before cleaning, always disconnect your PA10 from the AC supply.
