Frequently Asked Questions
What is ruler-flat frequency response, and why does it matter for recording?
A ruler-flat response means the microphone reproduces all frequencies equally without boosts or dips, allowing mixing engineers complete control over tone; the CK61 ULS delivers this, making it ideal for critical studio recording where accuracy is paramount.
How does the CK61 ULS support consistent cardioid polar patterns across frequencies?
Professional small-diaphragm design in the Ultra Linear Series maintains a stable cardioid pattern even at high frequencies, preventing the polar pattern from narrowing or shifting—essential for multi-microphone studio setups and stereo recordings.
What types of acoustic sources is this capsule suited for?
The CK61 ULS works excellently on instrument sources (drums, piano, guitar amps), string sections, and overhead ambience in recording studios, as well as drum overheads and percussion in broadcast sports production.
Can the CK61 be used for both classical music and modern recording?
Yes; its transparent, neutral character makes it equally at home capturing a live orchestra, chamber ensemble, or contemporary rock drum kit, depending on mic placement and mixing context.
Which preamp is the CK61 ULS designed to work with?
The CK61 ULS is engineered for the C480 B preamp, which supplies phantom power and provides the necessary impedance matching and amplification for studio-quality recording.
How do gold-plated contacts enhance long-term recording studio reliability?
In a studio environment where precision audio is essential, gold contacts prevent oxidation and intermittent connection issues that could degrade recordings or create session downtime.
How quickly can Procure.ae supply the CK61 ULS to recording studios in the UAE?
Contact Procure.ae for current stock status and delivery timelines; lead times may vary based on your location and whether the C480 B preamp is needed alongside the capsule.
Does Procure.ae stock C480 B preamps, or do I need to source them separately?

What exactly does the CK61 ULS package include?
You receive the small-diaphragm cardioid condenser capsule; the C480 B preamp, cables, shock mount, and windscreen are sold separately as part of a studio microphone system.
Is the CK61 ULS suitable for broadcast live sound?
While the CK61 ULS is engineered primarily for studio recording and critical broadcast use, contact Procure.ae about compatibility with your live sound or broadcast infrastructure.
