Εδώ και λίγο καιρό, σκέφτομαι πολύ σοβαρά την απόκτηση μιας συσκευής που να μπορεί να "επέμβει" στο χώρο μου και να "διορθώσει" -εί δυνατόν- τις κακοτοπιές του.
Και αναζητώ λύση σε τέτοια συσκευή μιας και όντας στο ενοίκιο, σε ξένο σπίτι, είναι δύσκολο να προβώ σε ηχητική φορντίδα του χώρου.
Με ένα τέτοιο μηχανάκι υποθέτω πως σε όποιο χώρο και αν βρεθώ στο μέλλον, ξαναμετρώ και παίρνω αποτέλεσμα.
Να σημειώσω εδώ, πως δεν είμαι και πολύ "χαρούμενος" που θα προσθέσω ένα ακόμα κρίκο στο σεταπ μου. Όμως πιστεύω πως η βοήθεια ενός τέτοιου μηχανήματος θα έχει περισσότερα θετικά στοιχεία να προσθέσει παρά αρνητικά. Ακόμα δλδ και αν εισάγει "άποψη" ή αν "χαλάσει/μαγειρέψει" τον ήχο, το όφελος απο τη διόρθωση του χώρου θα είναι σημαντικότερο/μεγαλύτερο.
Έχω καταλήξει λοιπόν, στις παρακάτω 3 λύσεις και θα ήθελα την γνώμη σας ή την εμπειρία σας αν τυχόν έχετε συμβιώσει με κάποια απο αυτές ή ακόμα και άλλες προτάσεις αν έχετε να καταθέσετε.
Μόνο μην μπλέξουμε με software που χρειάζονται ρύθμισμα, χρόνο, γνώσεις και πολλές μετρήσεις κλπ κλπ. Είναι βασικό να μιλάμε για μια λύση -almost- plug n play.
Δυστυχώς και τα 3 μηχανάκια βρίσκονται δύσκολα ακόμα και στην αγορά των μτχ.
Το δε RP-1 έχει καταργηθεί και επίσημα απο την Lyngdorf. Για το Copland δεν γνωρίζω, αλλά στο επίσημο site της εταιρίας δεν υπάρχει.
Lyngdorf RP-1 Room Processor
Features
The RP-1 is a standalone room correction processor that can be inserted in any conventional pre-/power amplifier set up. This is the simplest way of removing room-generated anomalies and the fastest way to improve the sonic performance of analogue audio system.
The effect of the RP-1 "Black Box" is magical - however, there is nothing mysterious about why it is so efficient. The "Black Box" simply introduces the world patented RoomPerfect room correction technology to improve the sound in analogue audio systems. In essence, the "Black Box" will improve sound reproduction in any audio system, from basic to very high-end set-ups.

Copland DRC205 Digital Room Correction
Features
The first impression of the Copland DRC-205 hides the fact that there are many more possibilities than the user friendly front panel reveals.
The predefined sound pro.les will satisfy the vast majority of music lovers. However, the more demanding users can store their own sound profiles via a standard Windows PC.
The Copland DRC-205 comes with a graphical user interface, which can be installed from the accompanying CD-rom. By installation on a standard Windows PC, an advanced equalizer can be accessed, allowing the user to adjust the frequency response in the room and to actually see the frequency response of the system on frequency curves before and after compensation.
Copland DRC-205 can be connected between the signal source and amplifier, or to any amplifier with an ordinary analog tape monitor in/output.
In co-operation with Dynaton, Copland ofiers the opportunity to upgrade the DDRC technology. Updates are done via user-friendly software available for download on the Copland and Dynaton websites.

McIntosh MEN220 Room Correction System
Features
The MEN220 delivers a potent suite of Room Correction, Custom-EQ and 2-Way Crossover capabilities in one easy-to-use stereo component. While any single feature of the MEN220 has the power to optimize the sonic characteristics of the highest quality audio systems, combining all the features can reveal a level of clarity and resolution unattainable by any other means.
Full system control and PC link are provided via RS232 while McIntosh data, power control and IR inputs offer additional remote control flexibility. Both single-ended and balanced connections are supported; a hand-held, IR remote control is included.
