Duo Mic Pre/ Variable Phase DI Portico™ 5016 The Portico 5016 is a half rack, 1U module that embodies a Microphone Preamplifier and a DI, which can be used separately or together to provide an innovative and powerful approach to the recording of musical instruments. Classic Musical Sweetness Both channels of the 5016 are transformer coupled which greatly assists with the avoidance of hum loops and ensures the classic musical sweetness for which Portico modules are well-known and the DI includes a powerful new Phase-Rotate control that allows the Direct Input to be manually phase aligned in relation to the microphone signal! The 5016 may be racked in the control room or placed out on the studio floor. It includes a full-featured, transformer coupled microphone preamplifier identical to the 5012 with Silk, a swept High Pass Filter from 20-250Hz, 48V Phantom, Phase Reverse and a total of 72 dB of Gain. The independent DI channel provides selectable Instrument or Line level inputs, with up to 35dB of gain for the instrument input. Direct Input Amplifier The DI channel accepts either Instrument or Line level signals via a balanced TRS jack on the front faceplate. When Instrument level is selected, the input impedance is 3 Megohms and the gain range is +20dB to +40dB. When the Line Input is selected the input impedance is 10K, and the gain range is from –10dB to +10dB, better suited for keyboards or instruments with on-board electronics. This input can also be used to monitor playback when comparing phase adjustments. The use of transformers greatly reduces grounding issues when using unbalanced equipment, however a ground lift switch is available on the front panel if ground loops cannot otherwise be avoided. A thru output is also provided on the front faceplate enabling a buffered and unbalanced unity gain signal to be sent to an external amplifier. Microphone Amplifier Section The microphone input is identical with the Portico 5012. It uses a balanced but not floating, transformer configuration. The microphone is presented with a very high input impedance that is protected with a Toroidal Common Mode Rejection Low Pass Filter to exclude frequencies above 150 kHz. The Microphone preamplifier thus uniquely permits a full +25 dBu input signal to be handled at unity gain without an input pad over the whole audio spectrum. The advantages of both an “Electronically Balanced” and true transformer input are obtained without the noise trade-off of the usual “pad” solution. When the Phantom voltage is switched off, the Microphone input serves as a very high quality line input with an impedance of 10,000 ohms. 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 FURTHER INFORMATION If you need any product information, or advice, or just the name of a dealer in your area who we recommend, please feel free to contact us anytime and we'll be glad to help out.
