1、BP26 OWNERS MANUAL RadioFans.CN 收音机爱 好者资料库 IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of un- insulated “dangerous voltage “ within the products enclosure that may be of sufficient magnitude to

2、constitute a risk of elec- tric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and mainte- nance (servicing) instructions in the literature accompanying the product. 1. Read these instructions. 2. Keep these

3、 instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturers instructions. 8. Do not install near any heat sources such as radiators, heat

4、 registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blad

5、e or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10.

6、it from the apparatus. 11. Only use attachments/accessories specified by the manufacturer. 12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used use caution when moving the cart/apparatus combination to avoid injur

7、y from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel.

Please note th

20、at it is important that your phono car- tridge is connected to the correct inputs in order to achieve proper performance. Input impedance is 180 ohms and sensitivity is 350uV DIGITAL AUDIO INPUT MODULE (OPTIONAL): The BP26DA model contains two SPDIF compatible digital audio inputs. To select either

21、the DAC-1 or DAC-2 digital audio input, first set the rotary SOURCE selector to DAC, and then select between the two SPDIF inputs with the DAC-1/ DAC-2 toggle switch. The digital-to-analog conver- tor can handle input sample rates from 16KHz to 108KHz, and word lengths of 16, 18, 20 or 24 bits. VISU

22、AL INDICATORS: MPS2 Power Supply: The LED on the front panel of the MPS2 lights GREEN when power is on. BP26 Preamp: The three colour LED (light emitting diode) located on the front panel lights RED when the output is muted, GREEN when the output signal is non- inverting polarity and YELLOW when the

23、 output signal is inverted with respect to the input. When the LED is unlight- ed, the power is off. FRONT PANEL CONTROLS: MUTE/NORMAL TOGGLE SWITCH: Mutes or releases mute at the main outputs, (not To Tape outputs), without changing the volume control setting, each time pushed. POLARITY/INVERT TOGG

24、LE SWITCH: Reverses polar- ity at main outputs each time pushed. (GREEN LED indi- cates positive polarity, YELLOW LED indicates inverse polarity). VOLUME CONTROL: Rotary control varies the output level to the MAIN OUTPUTS, (does not effect TO TAPE outputs). BALANCE: Rotary control adjusts the left-v

25、ersus- right channel levels. BALANCE CONTROL: is a tailored-inflection type which has very gradual action near the center of rotation allow- ing fine adjustments to the stereo image. For convenience the electrical center of the control is detented. SOURCE SELECT SWITCH: Rotary switch determines whic

26、h input will appear at the “TO TAPE” outputs for recording or processing, as well as determining which pro- gram is available at the Main outputs. (When the “TAPE/ SOURCE” switch is in “Tape” position, “FROM TAPE” inputs appear at Main Outputs). MONO/STEREO SWITCH: “Stereo” position provides two-cha

27、nnel stereo at the Main outputs. Mono position sums the main outputs to monaural. The TO TAPE out- puts are always stereo. (Switch not present on “-MC” or “-DA” models). MC/MM PHONO SWITCH: This switch is present on the BP26MC models only. It allows the selection of either Moving-Magnet or Moving-Co

28、il phono equalization. This switch takes the place of the “Mono/Stereo” toggle switch on other BP26 models. DAC-1/DAC-2 TOGGLE SWITCH: Only on BP26DA mod- els, this switch determines which of the two SPDIF digital audio inputs is processed and then sent to the tape and main outputs. The SOURCE selec

29、t switch must also be in the “DAC” position to monitor the digital audio inputs. TAPE/SOURCE SWITCH: “Source” position monitors whichever input is selected at the rotary SOURCE selec- tor rotary switch. “Tape” position provides monitoring of the “FROM TAPE” input for A/B comparison with the source. Should an external processor or equalizer be connected in the tape loop, the TAPE / SOURCE” switch will act as an in/out switch for the external equipment.
