The Portico 5042 True Tape FX uses genuine tape drive circuitry to create a remarkable simulation of the magic that is known as tape saturation.

The Portico 5042 True Tape FX uses genuine tape drive circuitry to create a remarkable simulation of the magic that is known as tape saturation. If the tape circuit is disengaged, the 5042 becomes a transformer-coupled line amplifier with a gain range of +/-12dB. Drop this all-analog processor on a drum bus or master bus and enjoy the warmth and natural compression that can only be achieved with tape. If you've switched to digital but still long for the days of tape, put the Portico 5042 in your rack.

The 5042 provides a remarkable simulation of true tape sound through the inclusion of genuine tape drive circuitry. When the Tape circuit is not engaged, the 5042 may be used as a full, transformer-coupled, high-performance line amplifier that includes a Gain range of +/-12dB. The Portico 5042 "True Tape" Emulation and Line Driver unit's emulation circuit provides the nostalgic rounding and compression usually only achieved by the use of tape. This typically offsets the harshness often found in digital recordings. The Portico 5042 incorporates an actual tape drive circuit that feeds a tiny magnetic "head" which, in turn, is coupled to a correctly equalized, replay amplifier. The only thing missing is the tape itself!

The Portico 5042 consists of two identical Line Driving amplifiers having transformer balanced inputs and outputs. The sonic quality of these amplifiers is such that, by providing galvanic isolation, simple single-sided circuit topology and freedom from grounding problems they are capable of enhancing the sonic quality of many signal sources, especially those of digital origin. The sonic "signature" is one of extreme purity and the image is consistent with that of Rupert Neve's original designs of 35-40 years ago.
