This new feature, called ActivEQ, combines active and passive components to create a specific EQ curve to suit a particular pair of headphones, performed in the analogue domain without a hint of additional noise or distortion.
The ZEN CAN Signature 6XX, features ActivEQ for the ‘MassDrop x Sennheiser HD 6XX’ – a popular pair of high-quality headphones with more than 120,000 sold to date, based on the Sennheiser HD 650 and created exclusively for Drop.com.
These headphones are renowned for the quality of their midrange performance but exhibit some quirks in the bass and treble regions, which can be seen in frequency response measurements. When the ‘HD 6XX’ button is pressed, the ZEN CAN Signature 6XX calibrates its signal to complement the headphone’s response characteristics right across the frequency range, thus tailoring its performance to precisely fit the HD 6XX like a made-to-measure suit.
What’s more, the benefits of this ActivEQ curve are equally applicable to the Sennheiser HD 650, which shares the same characteristics. It also has an effect on other Sennheiser models – take a look here.
This feature can be switched on or off. Without ActivEQ engaged, the ZEN CAN Signature 6XX’s performance is adroitly balanced to make the most of all manner of headphones and in-ear monitors.
Not in the case of the ZEN CAN Signature 6XX. It features four gain settings in six dB steps – 0dB, 6dB, 12dB and 18db.
This enables the amp to precisely suit the connected headphones. Unity gain (0dB) is useful to ensure low noise with sensitive in-ear monitors, while the higher gain settings make the most of tougher headphone loads, delivering excellent dynamic headroom.
