CR Development Romulus


Remus was a natural development in the CR product range, offering more power and larger dynamic range than the smaller Romulus amplifier.

 

Remus is configured as a power amplifier with no switchable inputs and is designed to match directly with our Carmenta or Kastor pre-amplifiers, although it will work well with any high quality pre-amplifier.

 

Although Remus has a dynamic quality, it retains the smooth response inherent in all CR amplifiers, reproducing the gentlest passage or most strident orchestration with equal ease.

 

Over-engineered internal electronics leave the amplifier unstressed even under the most demanding conditions. No expense was spared where component selection was concerned, with the best signal components being used throughout all critical paths leaving the audio untarnished and full of its original vitality.

 

Transformers, always a key component, are exceptionally large. Less conservative designers would probably use them in 200 Watt output stages!

 

With so much power in hand, loudspeaker selection is not critical and can match the listener’s taste without worrying about sound level and dynamics.

Open and dynamic are words often used to describe the CR324SE.


CR’s traditional links to the professional audio field led to an amplifier design based on a studio monitor product, which seemed a natural move.

Making a similar product available for Hi-Fi use was irresistible.


Heavy current output circuits and design simplicity are the hallmark of this design. The best available output transistors are used, lower cost types being rejected as inconsistent or unreliable.


The CR324SE is intended for use with 4 to 8 ohm loudspeakers; although it’s exceptional drive capability will cope well with loudspeakers, presenting wide impedance variations across the audio spectrum. Internal self-regulating circuitry and thermal control will protect the amplifier from accidental abuse, allowing it to recover without recourse to service engineers or dealers.

This capability also reflects in higher power performance, with an almost pro-rata increase in output between eight and four ohm loads.


The sound is never harsh; light musical passages being faithfully reproduced with an easy transition to full orchestration or rock music.
