The all new Halcro Eclipse amplifiers herald a new era in the Halcro story. The original Halcro dm amplifier hit the market to disbelief – orders of magnitude lower distortion than anyone believed possible. The Eclipse amplifiers take musical expression to a new height.
The new Halcro team have spent the past couple of years exploring every aspect of the unique platform for possible improvements. We present – the new reference in amplification.
Available in both stereo and mono versions, the Eclipse series is unparalleled in its ability to render details formerly lost in the distortion.
The Eclipse enjoys a completely redesigned input stage, further reducing non-linear effects and distortion. There are multiple independently tracking power supplies, superior internal shielding and higher output power. Finally the Eclipse amplifier offers a new, modern, ‘lighter’ take on the distinctive and award winning Halcro aesthetic. Even this contributes to better performance with the new, machined-from-solid casework reducing microphonics.
(Measured at 1kHz)
There are four input modes:
The voltage gain of the balanced and unbalanced inputs is 30 V/V and for the minimal path mode is 15 V/V. The gain of the current mode is 9 V/mA
The equivalent input noise at the input is 5 nV/sqrt(Hz) for the voltage modes and 6 pA/sqrt(Hz) for the current mode.
(Measured at 1W output)
Maximum slew rate for both small signal and maximum output voltage is 100V/μs (which is equivalent to a maximum output voltage at approximately 250 kHz).
The amplifier protection:
The power supply protection:
For reliability, all semiconductors are at least industrial grade in both the power supply and amplifier. All electrolytics are rated to 105°C in both the amplifier and power supply.
There are four heavily shielded compartments:
Series and common mode EMI filtering is present:
High frequency filtering is present at the inputs and output.
