Mimesis 24

Goldmund PreAmplificadores Mimesis 24


The introduction of the Mimesis 24 has considerably changed the market of multi-channel processors. The number of possible channels (up to 32), the freedom to distribute any number of speakers in a room in order to achieve maximum coverage in both bandwidth and space recreation have totally changed the today's usual limits, achieving levels of reality never thought possible before.

Compatible with all kind of sources, outputting 32 channels in 96kHz 24 bits high resolution digital format, the Mimesis 24 is rapidly becoming the reference preamplifier-controller of any ultra-high-level Audio and Video system, even in 2 channels.

By outputting only digital signals, it allows large installation to run only digital cables, with far less quality loss than with analogue interconnects.

Its internal algorithms have been developed with Goldmund typical sound quality in mind. The comparison with other top processors existing is showing the considerable gap the Mimesis 24 created in sound quality for 2-channel or multi-channel The introduction of the Mimesis 24 has considerably changed the market of multi-channel processors. The number of possible channels (up to 32), the freedom to distribute any number of speakers in a room in order to achieve maximum coverage in both bandwidth and space recreation have totally changed the today's usual limits, achieving levels of reality never thought possible before.

Ph 3

Goldmund PreAmplificadores Ph 3

Totally new by its approach as well as per its circuitry the Mimesis PH3 provides the typical top Goldmund qualities to the most demanding Vinyl collectors.
MM and MC separate inputs, gain adjustment, complete set of cartridge loading adjustments separate for each channel makes it a dream to use.
The quality of its most advanced circuitry gives it a transparency and a spaciousness that the typical "glamour" sound of analogue may have masked for you for too long.
The most unusual part of the design is the extremely short signal path of the amplification circuitry. The printed board is directly assembled on the rear panel and the circuit is located just between the plugs. The whole design is dual-mono.

Specifications

Gain MM input : 43dB (low) and 50dB (high)

Gain MC input : 63dB (low) and 70dB (high)

RIAA curve : -0.03 dB / +0.06 dB max derivation from RIAA curve

Gain Stage response (without RIAA correction) : - 3dB 0.12Hz - 760 kHz at 70dB gain

Rise time : < 400 ns

Distortion : < 0.007% (20Hz-20kHz at 4V rms output)

Output Impedance : 50 Ohms

Max output level : 32Vpp
