Rupert Neve Designs 542 Tape Emulator with Silk - B-Stock

Rupert Neve Designs 542 Tape Emulator with Silk - B-Stock

The Rupert Neve Designs 542 is a tape emulator that's a follow-up to the Portico 5042, the 542 delivers the same thick, musical simulation of tape while drastically enhancing creative control via a number of new features. In addition to the “true tape” circuitry – great for bringing out 3rd-order harmonics – the 542 incorporates a soft-clip circuit that tames the harshest sources and enhances 2nd-order harmonics, a variable and versatile Silk/Texture circuit for three transformer tones in one, and a wet/dry control to blend in the perfect amount of saturation.

This is a B-Stock item. The unit comes with all of the original packaging and full manufacturer warranty.

Unlike digital emulations, the “True Tape” drive circuit works by feeding a custom-designed transformer acting as a “record head”, which in turn is coupled to a correctly equalized replay amplifier. As the voltage rises on the “record head”, saturation increases, and a soft clip circuit engages at higher levels to round off peak transients. The sound of the tape circuit can be further modified with selectable 15 / 30 IPS modes and a pre/post-tape blend control. In addition to the tape circuit, the 542 also has the variable Silk & Texture circuitry found in the Portico II series of modules, which allows the engineer to fine-tune the harmonic ratio and tonality on the output transformer.

Features

Tape In
Sends the signal through the “True Tape” circuitry, which is affected by the saturation, blend and 15 / 30 IPS controls.

Trim
Provides +/– 12dB adjustment of level on incoming signal levels, prior to the tape circuit.

Saturation
Controls the signal level being sent to the “tape head” circuit. As the saturation level increases, the level on the “record” head rises, and the replay gain is reduced so that the overall output signal level remains more or less constant. In a real tape recorder, you would adjust the record and replay gain controls separately – however, in the 542 the record and replay gain controls are coupled so that the overall signal level only varies as the “Tape” saturation level changes. As you approach maximum saturation setting, the output signal level will drop due to the effect of extreme saturation and soft clip.

15/30 IPS
Selects the pre-emphasis / de-emphasis, record / replay tape characteristic. The 15IPS mode has a significant “head bump” in the low frequencies centered around 60Hz, as well as a more pronounced roll of in the high frequencies. The 30 IPS mode is generally a flatter response through the high-end with a “head bump” around 120Hz. See the frequency plots on pages 10 & 11.

Blend
Controls the mix of pre and post tape signals. This allows the engineer to dial in a subtle amount of the tape effect, to better control the amount of saturation, tone and soft clipping in the post blend signal. As the signal gets more saturated, dialing back the blend can be a great way to impart the feel of tape, while maintaining a similar level of detail and transparency. NOTE: The blend control does not affect the Silk and Texture controls, as that circuitry is located at the physical output of the unit.

Soft Clip
A soft clip engages in the “True Tape” circuitry when the drive meter hits 5 (first yellow LED), and becomes more apparent at higher levels. The soft clip can be used as a way to tame overly transient material like drums, and can be controlled further by using the blend control.

Silk/Texture
Pushing the Silk button engages the Silk Red circuit, and pushing it a second time introduces Silk Blue circuitry. Silk reduces the negative feedback on the output transformer, adding harmonic content as the texture is increased. Silk Blue mode features more saturation in the lows and low mids, whereas Silk Red accentuates the saturation in the high mids and highs.
