User manual LAVRY MP10 REV1.0

[. . . ] AC POWER: The MP10 automatically adjusts to AC power inputs in the range of 90 to 264 Volts AC and line frequencies between 47 and 63 Hertz. There are no settings to change. 1 OPERATION: A. Front Panel The MP10 has three toggle switches on the front panel. There is an individual gain adjustment for each channel, and a three position toggle switch to enable or disable the phantom power for each channel. [. . . ] Exceeding this level when feeding a "-10" input may result in clipping at the input stage of the "-10" device. Meters The output level is displayed on two 14 segment LED meters covering the range from -46 to 0 dB's below peak output level. For balanced outputs peak level is +24 dBu, and for unbalanced outputs peak level is +18 dBu. Phantom Power for Condenser Microphones The three position momentary toggle switch located between the two numeric GAIN displays (labeled "phan. ") is used to select +48V Phantom power for each channel, individually. Clicking the switch once in the up direction will enable or disable the Phantom power on the left channel, and clicking the switch once in the down direction toggles the right channel Phantom power on or off. The decimal point in the GAIN display of the appropriate channel illuminates when the Phantom power is enabled. Impedance Switch There is a toggle switch labeled "hi z" or "lo z" located on the back panel between the input and output XLR connectors. The "lo z" position should be used for low impedance Dynamic or Condenser microphones, and the "hi z" position optimizes the input impedance for Ribbon microphones. When AC power is applied, the setting of this switch is displayed in the right GAIN display during initialization. 2 G. Balanced/Unbalanced Switch The XLR outputs of the MP10 are electronically balanced and should not be connected to an unbalanced input without first setting the rear panel switch to "unbal. " Doing so will not cause damage to the amplifiers, but will raise the distortion level of the outputs significantly. The switch is located between the two sets of XLR connectors and is labeled "bal" and "unbal. " The peak output level is reduced from +24 dBu to +18dBu when the switch is set to "unbal. " After AC power is applied, the setting of this switch is displayed in the left GAIN display during initialization as "ba" for balanced and "Ub" for unbalanced. SPECIFICATIONS: Distortion- Measured at -3dBFS (21dBu) at 1kHz, 10kHz, &20kHz: Gain Setting 20 Gain Setting 40 Gain Setting 60 Less than 0. 00070%dBFS Less than 0. 00090%dBFS Less than 0. 00800%dBFS Noise- Input referenced noise at Gain Setting 40 with -999dBr input 150 Ohm source Less than -124dBu (Unweighted) Less than -127dBu (A-Weighted) Inputs- Transformer-free electronically balanced Pin 2 "+" XLR inputs with common hi/lo impedance switch. Phantom Power- +48 volts Phantom power for condenser microphones, can be enabled or disabled for each input channel individually using front panel switch. Outputs- Transformer-free electronically balanced outputs. Rear panel switch for balanced Pin 2 "+" or unbalanced Pin 2 "Hot" operation. Meter- 14 segment LED meter per channel, displays output signals ranging from -42 to 0dB below peak output level. Maximum balanced peak output 24dBu, maximum unbalanced peak output is 18dBu. Dimensions and Weight- 8"wide x 10. 75" deep* x 1. 75" high, 4. 5 lbs *depth includes clearance for front and rear panel switches and connectors AC Power: Voltage 90-264 VAC, Frequency 47-63Hz, Current 0. 1A Fuse Rating 4A "Fast Blow" * *Subject to change!Please always check the rating on the fuse and the one printed next to the fuse holder on the power supply PC board before replacement.
