One of the key features of the 511 is the Silk / Texture control. The Silk circuit was initially developed for the original Portico series mic preamplifiers, and was only a single switch on or off that added a specified amount of musical, pleasing harmonic saturation to the units output stage. Taking this concept one step further, the Texture knob is designed to adjust the actual amount of harmonic content from the source material. So how does it work? GAIN A 12-way precision rotary switch controls gain from 0 to 66 dB in 6 dB steps.
When the Gain switch is set to Unity (0 dB), the 511 can handle a balanced input signal of more than +20 dBu without an input attenuator pad this is a unique feature that allows the 511s Silk circuit and other features to be applied to line-level sources. TRIM Continuously variable +/-6 dB control to fine-tune level. +48V Engages phantom power on the microphone input, as supplied by the 500 series rack.
LEVEL METER An eight-segment LED bar-graph meter displays output level (pre-Silk). The color range proceeds from green for lower level signals, yellow for intermediate signals, and red for high levels. When the 511 is clipped, the highest red LED will hold longer depending on how far above the clip threshold the signal was. POLARITY Push button inverts the polarity of the signal path, and illuminates when engaged.
The symbol Ø is often used to denote opposite polarity. HIGH PASS FILTER The high pass filter is continuously variable from 20-250Hz and engaged by the HPF switch, which illuminates when engaged.
It is a valuable aid in any signal chain, but particularly so in a microphone preamplifier. SILK / TEXTURE Pushing the Silk button engages the Silk Red circuit, which enhances harmonic content generated by the highs and high mids of your source.
This adds a sparkly sheen to the top end, and is often ideal for sources including vocals, strings, pianos, and other acoustic instruments. With Silk / Texture engaged, the distortion characteristic and harmonic content of the unit are very reminiscent of many of Ruperts class-A vintage designs. By manipulating the Texture control, the amount of Silk can be changed from essentially absent, to well beyond the amount of coloration found in vintage units. Specifications NOISE Measured at Main Output, un-weighted, 22 Hz - 22 kHz, source impedance 150 Ohm balanced.Noise performance can vary depending on the 500 series and / or interference from stray magnetic fields. Trim continuously adjustable from -6 dB to +6 dB.
PHANTOM POWER Supplied by the 500 series rack power supply. HIGH PASS FILTER Continuously variable swept frequency from 20 Hz to 250 Hz.
