AMS Neve 8051

Based on six 2254 compression circuits - using the same feedback topology as our legendary 33609 stereo compressor - the 8051 delivers the famous Neve sound in spades. Flexible side chain routing, trimming and filtering make this a powerful and responsive tool for surround mixing and mastering.

• Hand-built, hand-wired analogue compressor for Surround mixing

• Six transformer-balanced audio paths

• Ideal surround broadcast or mastering compressor

• Side Chain control trims and Side Chain A/B bias control

• High and low pass filter

• Electronically balanced key input and LFE filter inputs

• All other inputs transformer-balanced with 3.6kOhms input impedances

• All outputs electronically balanced, post output transformers

• Maximum output: +26dBu into 600 Ohms

• Control Voltage I/O provided for linking multiple units, or linking to 33609

• EIN (20kHz band): <-78dBu

• THD+N (for 20dBu input @ 1kHz): <0.03%

• Maximum Output Level: >26dBu into 600 ohms

• Interchannel Crosstalk: <-80dB at 15kHz

• Frequency Response ±0.5dB 20Hz to 20kHz

LEVELS:

Frequency Response: +/- 0.5dB from 20Hz to 20kHz, measured at 0dBu relative to 1kHz

Distortion (80kHz bandwidth): 0.075% maximum (Bypass IN, Compress and Limit OUT, input level at +9dBu, 1kHz)0.2% maximum (Compress IN ratio 6:1, Gain make-up to MAX, Recovery: 800mS, Threshold -18dBu)0.45% maximum (Limit IN, Compress OUT, Recovery 800mS, Input level +22dBu, Threshold -18dBu)

Noise: -75dBu with input terminated in 600 Ohms, Bypass IN, Compress and Limit OFF; -55dBu with compress IN and gain make-up at maximum (22Hz to 22kHz bandwidth)

LIMITER SECTION:

Limit Threshold: +4dBu to +15dBu

Limiter Ratio: With input level at 10dBu, then increased to +20dBu, the change in output level should be 0.1dB, +/-0.1dB

Limiter Attack Time: Slow 4mS, +/-1mS, fast 2mS, +/-1mS

Limiter Recovery Time: A1 (auto): 100mS/2seconds, A2 (auto): 50mS/5seconds

COMPRESSOR SECTION:

Compressor Ratio: 1.5:1, 2:1, 3:1, 4:1, 6:1

Compressor Attack Time: 3mS

Compressor Recovery Time: 100mS, 400mS, 800mS, 1.5S, and Auto 1 (100mS/2 sec) and Auto 2 (50mS/5 sec) settings.

Compressor Gain Make-up: Gain Make-up control provides 0dB to +20dB extra gain in 2dB steps when Compress switched IN.
