The Spectra 1964 model V610 is a required addition to any mastering suite. In many mastering signal chain configurations, the V610 is used as the first device, as a peak limiter. The result is dramatic and measurable. With the elimination of audio program peaks, (inaudibly), signal processing devices that follow the V610 have headroom increases of 6-12dB, a reduction of noise and overload distortion, and provide extended harmonic content that is lost during conventional amplifier overload. 

​

In the audio tracking environment, the V610 will rival and, in most cases, exceed any stand-alone or mixing console microphone preamplifier in terms of headroom, articulation of

harmonics, and overall reduced distortion. As a vocal microphone preamplifier, excessive level

changes will be easily accommodated by a compression circuit that is both fast and

transparent. Guitar tracks will be both accurate and harmonic-rich. For the first time, many

musicians will experience the true sound of an instrument operating in a peak free

environment.

Like other Spectra 1964 Complimiter products, the V610 shares the revered and unequaled 601 Complimiter module. Originally introduced in 1969, the 601 set a standard that is well beyond the capabilities any other compressor limiter circuit. The V610 is an enhanced version of the C610 in that it allows for easy recall of prior settings in a high-resolution dB format. The ultra high-quality Elma switches feature mil-spec metal film resistors, and long-lasting contacts. In fact, the three space format of the V610 is due to the physical size of the switches on the control surface. In addition, the V610 employs the model 110A amplifier for makeup gain. The result is low distortion and noise, with a +24dBu output, (irrespective of audio transient peaks).
