Audiolab DC Block 6 - Black
Το DC Block 6 έχει σχεδιαστεί για να βελτιώνει την ποιότητα της ηλεκτρικής ενέργειας εναλλασσόμενου ρεύματος που τροφοδοτεί τα συστήματα ήχου και AV. Το ηλεκτρικό ρεύμα έχει θεμελιώδη επίδραση στο ηχητικό σήμα καθώς περνά μέσα από ένα σύστημα, από την πηγή έως τους ενισχυτές έως τα ηχεία. Η παροχή ρεύματος σε ένα τυπικό σπίτι υπόκειται σε παρεμβολές που προκαλούνται από μια σειρά προβλημάτων, προκαλώντας την παραμόρφωση της κυματομορφής AC πριν φτάσει σε κάθε εξάρτημα. Αυτό δημιουργεί θόρυβο στο ηχητικό σήμα, το οποίο υποβαθμίζει την ποιότητα του ήχου – μια κατάσταση που συνεχίζει να επιδεινώνεται με την προσθήκη ολοένα και περισσότερων ηλεκτρικών συσκευών στο ηλεκτρικό δίκτυο του σπιτιού.

DC mains supply
One common issue is ‘DC on the mains’ – a problem that is well known to affect the performance of audio equipment, especially amplifiers. In theory, the mains electricity we obtain from the sockets in our homes should be pure AC, with a perfectly symmetrical sine wave alternating between positive and negative phases.
DC Voltage
The AC transformers commonly used in home audio equipment cannot tolerate the presence of significant levels of DC voltage without being compromised. Less than 500mV of DC – typical in an average household electricity supply – can be sufficient to cause toroidal transformers of the kind often found in amplifiers to become saturated, which adversely affects sonic performance and may cause audible mechanical vibration.
The audiolab DC BLOCK 6 is a six-way solution for this all-too-common problem.
By blocking, or cancelling, DC voltage found within the AC mains supply, the DC BLOCK 6 corrects the DC offset and rebalances the mains sine wave. But tackling ‘DC on the mains’ is not the only benefit delivered by this dual-action device – it also contains a high-performance audio-class filtering circuit that removes RFI/EMI contaminants from the mains supply. This is effective in reducing both differential-mode noise (exacerbated by cheap switch-mode power supplies used by many home appliances) and common-mode noise (aggravated by airborne interference from phones, Wi-Fi networks and Bluetooth).
A specialised six-way power optimisation device of such impressive efficacy, DC block 6 is available in black or silver. It comes with a full set of power cables – six IEC C14 to C13 cables to connect its outlets to the user’s system components, plus a cable to plug it into the mains.

Simple setup
The DC BLOCK 6 has one single mains input and offers six IEC outlets for the mains power supply of your audio system components.
Perfectly sized to match audiolab components and to easily fit into a typical hi-fi shelf/rack system, the DC BLOCK 6 also features a front-panel voltmeter display (which can also be powered off for a more discreet placement).
• Suitable for all audio or AV systems
• Removes DC from AC mains supply, transformer hum, and RF interference
• Offers radical improvement in mains quality, transformer and power supply performance, and therefore sound quality
• Six independent outlets for source components; power amps, preamps, integrated amplifiers, CD players, DACs, etc.
• One single mains input connection
• Simplified OLED display on voltmeter with display on/off option
