Rupert Neve Designs Portico 5012 Duo Mic Preamp
ไมค์ปรีแอมป์ Neve 5012 2-Channel Microphone Preamp มีทั้งแบบแนวตั้ง 5012-V (Vertical) และแบบแนวนอน 5012-H (Horizontal) เพื่อสะดวกสำหรับการใช้งานแต่ละสถานที่โดยมีคุณสมบัติที่เหมือนกัน
The Portico 5012 is a dual channel mic pre featuring Rupert Neve’s custom input and output transformer designs. In addition to individually selectable phase, mute, phantom power and a fully sweepable high pass filter, the 5012 incorporates a “Silk” circuit which yields the rich warmth and presence of his renowned classics.
Features:
- Dual-Channel Microphone Preamplifier
- Silk Circuit
- Continuously Sweepable High-Pass Filter
- Connect to Multiple Buss Modules
- Mute Button
- Phantom Power
- Phase Button
Silk
Much could be written about this feature, suffice to say, that it gives a subtle option to enhance sound quality in the direction of vintage modules. The Silk button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance. We suggest you try it and make your own judgment.
Level Meter
-30 dBu to +22 dBu With reference to the output
Mute
Cuts of the output signal post metering and pre Buss Output. Be sure to mute the outputs before engaging phantom power.
High Pass Filter
The High pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals between 20 and 250 Hz can be attenuated, leaving the range above this unaffected. This gets rid of building rumble, air handling motor hum etc.
Phantom Power
Provides 48V phantom power to microphones
Buss Output
The To Buss output is unbalanced and has a high impedance output. It is intended for use with the Portico Buss Amp/Monitoring modules. A TRS patch cord is used to connect the 5012 Buss output to one of these bussing modules. The Monitor connection is derived pre mute on the 5012 and will produce a signal at the output of the buss modules that is equal in level to that at the 5012 output. The Monitor output cannot be used for any other purpose.
Polarity
Flips the phase of an incoming source 180 degrees
