MICPRE ONE is one of the first in our flagship “Designed by Langley” series of pro-audio products. Yes, as the name reveals it is designed by Mr Graham Langley, a name that requires no introduction. The premium quality components are used without any exception to provide the highest performance and most reliable operational life. The PCBs are fully gold plated. Nothing is compromised.
MICPRE ONE is similar in topology to the transformerless design Graham used on the Amek M2500 mixing console and the original Angela console of 1982.
A number of improvements have been made, but the design retains the use of parallel matched transistors and constant current sources. Exceptional noise performance has been achieved. Particularly at low gain settings. The signal path is balanced throughout.
0dB to 66dB of gain is selected in 6dB steps by a rotary switch and this is followed by the fader stage which provides an additional 4dB of gain and up to 24dB of control to adjust between switch settings and also to attenuate the final output to suit consumer interface.
Switches are fitted for input impedance selection, a passive high pass filter before the preamplifier, phase and phantom power.
A high impedance balanced instrument input is also provided on a front panel jack.
An additional switch selects the source for a second front panel that can provide a balanced “THRU” output directly from the instrument source, or monitor off the main path.
An 8 segment pre fader LED meter is provided. The Signal Present LED illuminates at -18dBu. The response of the main bar approximates that of a PPM, while the +18 LED has faster attack and slower decay to catch peaks.
Typical specifications both paths:
|Mic. input impedance:||switchable 5k ohms/600 ohms|
|Instrument input impedance:||switchable 1.5M ohms/50k or 10k ohms|
|High pass filter:||120Hz @ 6dB/octave (nominal).|
|Frequency response:||+/- 0.5dB, 20Hz-80kHz (up to 60dB gain).|
|Phase response (EQ out):||+/-30 deg., 20Hz-80kHz (up to 60dBgain).|
|Maximum output (into 100k ohms):||+27dBu|
|THD&N (+10dBu input signal):||better than 0.05%, 20Hz-20kHz (up to 60dBgain).|
|Mic. EIN, 22Hz-22kHz, RMS, 150 ohm source:||-128dBu.|
|Output impedance (main and THRU):||75 ohms|
