[. . . ] Also bear in mind that other equipment may radiate strong hum fields which could spoil the performance of your Portico module. If any liquid was spilled such as soda, coffee, alcoholic or other drink, the sugars and acids will have a very detrimental effect. Sugar crystals act like little rectifiers and can produce noise, "crackles" etc. SWITCH OFF IMMEDIATELY because once current starts to flow the mixture hardens, can get very hot (burnt toffee!) and cause permanent and costly damage. [. . . ] There are no special requirements for these PorticoTM low voltage power units other than that they must be of good quality, reliable and able to supply enough current for the number of PorticoTM modules in use. The power unit(s) supplied with your PorticoTM meets these requirements. 2 FEATURE LIST 5042 Two Channel "True Tape" Emulation/Line Amp Front Panel Level Meter Reads a) Input level from 0 to +22dBu b) Signal level being sent to tape 7. 5 / 15 IPS Selects emphasis/de-emphasis record/replay Tape characteristics INPUT LEVEL TAPE LEVEL SATURATION 7. 5IPS 15IPS Meter Selector Selects the meter to read between input level or tape magetization level A Portico Series The 0 2 4 6 10 14 18 22dB B 0 2 4 6 10 14 18 22dB INPUT LEVEL TAPE LEVEL 7. 5IPS 15IPS LINE-UP LINE-UP 0dB 0dB SATURATION 5042 LINE AMP TAPE FX -12 TRIM +12 ENGAGE TAPE TO A BUSS MIN MAX -12 TRIM +12 ENGAGE TAPE TO B BUSS RUPERT NEVE DESIGNS MIN MAX Engage Tape Inserts "tape circuit" when pressed or high quality line amplifier when depressed Trim Control provides +/-12dB adjustment to compensate for incoming signal levels prior to the tape circuit To Buss Sends signal To Buss output Saturation Level Controls the signal level being sent to the magnetic "tape head" 5042 Two Channel "True Tape" Emulation/Line Amp Back Panel Power Switch Disconnects supply from internal power converters Input Transformer-coupled balanced and floating 1 = GND 2 = HOT 3 = COLD 5042 + LINE AMP TAPE FX B A 12VDC POWER A BUSS B BUSS OUTPUT INPUT OUTPUT INPUT DC input jack 2. 1 x 5. 5 x 9. 5mm Center Positive PorticoTM Bussing System Connect as many units together as you'd like to create your own mixes using optional bussing modules Top and bottom rows are normalled together to allow for an IN / OUT / THRU configuration Output Transformer coupled Balanced and floating 1 = GND 2 = HOT 3 = COLD 3 PRIMARY FEATURES The PorticoTM 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. More detailed discussion on the sonic image and the way in which an analog designer's approach can sweeten and "warm" some of the cold, storage and editing processes, may be found on rupertneve. com. Control Functions TRIM control provides +/­ 12dB adjustment of gain to compensate for incoming signal levels prior to feeding the TAPE circuit ENGAGE TAPE push button inserts the "Tape" circuit when pressed (illuminated). The Meter push button switch selects the meter to read INPUT LEVEL or TAPE SATURATION LEVEL INPUT LEVEL reads the balanced signal level at the input of the PorticoTM 5042. TAPE LEVEL reads the signal level being sent to the simulated Tape Head. (Equivalent to Record Level in a real Tape Recorder) LINE UP The incoming signal level should be set by adjustment of the "TRIM" control so that this first LED starts to light (0 dB). When the Meter Selector is set to TAPE LEVEL there is no meter reading unless ENGAGE TAPE push button is pressed, . 7. 5 IPS ­ 15 IPS Push button selects the emphasis/de-emphasis, Record/Replay Tape characteristic. SATURATION Controls the signal level being sent to the magnetic Tape Head. As the SATURATION level increases, the replay gain is reduced so that the overall IN/OUT signal level remains more or less constant. In a real Tape recorder, you would adjust the Record and Replay gain controls separately. In the PorticoTM 5042 the Record and Replay gain controls are coupled so that the overall IN/OUT 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. The PorticoTM 5042 host line amplifier has a much higher output level capability than the "Tape" circuit embodied within it. The gain of the Record and Replay amplifiers has been adjusted so that with the TRIM control set to 0 dBu and the ENGAGE TAPE button OUT, an incoming signal of 0 dBu, will cause the first meter LED to illuminate. With the ENGAGE TAPE button pressed and the SATURATION control at MIN, the same first meter LED will continue to light regardless of whether the meter Button is IN or OUT, i. e. With the meter switched to TAPE LEVEL, rotating the SATURATION control Clockwise progressively illuminates the LEDs. With the SATURATION control rotated to MAX, the maximum recommended Record level is achieved. At MAX, with an incoming 0 dBu signal, the Tape circuit is running just below clipping point 4 PRIMARY FEATURES A Portico Series The 0 2 4 6 10 14 18 22dB INPUT LEVEL TAPE LEVEL SATURATION 7. 5IPS 15IPS B 0 2 4 6 10 14 18 22dB INPUT LEVEL TAPE LEVEL 7. 5IPS 15IPS LINE-UP LINE-UP 0dB 0dB SATURATION 5042 LINE AMP TAPE FX -12 TRIM +12 ENGAGE TAPE TO A BUSS MIN MAX -12 TRIM +12 ENGAGE TAPE TO B BUSS RUPERT NEVE DESIGNS MIN MAX If the incoming signal is low, (for example from a consumer Hi-Fi source), it is recommended that you rotate the TRIM control clockwise to bring the incoming signal up to the point where the first, or LINE UP LED is just illuminated. [. . . ] The effect on certain musical instruments is quite incisive, producing the characteristic coloring of a real tape recorder. However, tape recorders are actually very good and these effects are not always obvious to the inexperienced listener. We did not set out to make a "bad" tape recorder! 6 SPECIFICATIONS Line Amp Specifications (Measurements with tape circuit disengaged) Noise: Measured at Main Output, un-weighted, 400 Hz-22 kHz, Terminated 40 Ohms Balanced. @ 200 kHz ­0. 50 dB ­3 dB Maximum Output Level: Balanced and Floating Transformer Output: Total Harmonic Distortion and Noise: @ 1kHz, +20 dBu output level, no load.
