Technische Spezifikationen

Input:

Balanced, using “Transformer-Like-Amplifier” (T.L.A.) with toroidal Common Mode.

Rejection Low Pass Filter that excludes frequencies above 150 kHz.

The T.L.A. is followed by an actual input transformer permitting a full +26 dBu input signal to be handled at unity gain without an input pad over the whole audio spectrum.

Combines the advantages of both an “Electronically Balanced” and true Transformer input.

When the Phantom voltage is disabled, this input serves as a very high quality Line Input.

Input Impedance: 10,000 Ohms + or – 20%

Noise:

Measured at Main Output: Input terminated with 150 Ohms.

Measured over band limited 22Hz-22kHz, Unweighted:

	With Gain at Unity:	Better than –100 dBu.
	With Gain at 66 dB:	Better than –62 dBu
	Equivalent Input Noise (E.I.N.):	Better than –128 dBu

Frequency Response:

Main Output, no load: @ 10 Hz, –0.2 dB
                                       @ 160 kHz –3 dB

Buss Output: measured at the Rupert Neve Designs 5014 Buss-mixer, Monitor

Amplifier Output: @ 10 Hz –0.2 dB
                                  @ 160 kHz –3 dB

High Pass Filter: Swept Frequency continuously variable from 20 Hz to 250 Hz., Slope: 12 dB/Octave.

Gain: Switched Gain from Unity to +66dB in 6 dB steps.

“Trim”: Continuously adjustable potentiometer from –6dB to +6dB with reference to setting on the Gain Switch.

Maximum Output Level: Balanced and Floating Transformer Output from 20 Hz to 40 kHz: +25dBu. (Clips at just over +26 dBu)

Mute: Mutes Main Output only. (i.e. Monitor remains “Live”)

Total Harmonic Distortion and Noise:

Main Output @ 1kHz, +20dBu output level, no load: Better than 0.001% (No high order Harmonics)

Silk Engaged: Approximately 0.2% Second Harmonic

Main Output @ 20Hz, +20dBu output level, no load: Better than 0.01%.

Buss Output @ 1kHz, +20dBu output level, no load, measured at the RND 5014  Buss-mixer, Monitor Amplifier Output: Better than 0.002%.

SILK FEATURE: The Rupert Neve Designs 5012 uses mainly single-sided amplifier circuitry that excludes any possibility of crossover distortion. The “SILK” button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance.

Buss Output: The Buss Output is designed to feed the 5014 and other Portico™ Series modules with Buss Inputs.

Crosstalk: Measured Channel to Channel: Better than –90 dB @ 15kHz

Phantom Power: +48 Volts DC +/– 1%

Main Power Required: (From External Power Unit) Voltage Range, 9 to 18 Volts DC.

Current consumption: @ 9VDC = 1.3 A typical @12VDC = 1A typical @15VDC= 800 mA typical @18VDC= 650 mA typical

Rear Panel Power Connector: 5.5mm X 2.1mm DC jack, Center Positive
