Its construction surpasses expectations for its price range, particularly evident in the precision-engineered dual-layer metal mesh guard protecting the capsule—both robust and meticulously structured. The finish rivals those of higher-priced models, exuding a premium tactile and visual appeal. Functionally, the microphone remains deliberately minimalist, omitting common features like pad switches, reflecting Alctron’s philosophy of prioritizing core performance over superfluous functionalities. Below are two sets of images showcasing the product’s exterior and detailed components.

The internal circuit design serves as a critical window into a microphone’s engineering rigor, technical commitment, and sonic potential—especially for condenser models. The images below illustrate the front and back of the CX5’s circuitry.

As shown, the microphone employs a dual-layer circuit board architecture, segregating functional zones such as "signal processing," "power supply," and "output." This structured layout enhances noise resistance, preserves signal-to-noise ratio, and ensures frequency response integrity, contributing to long-term reliability. Notably, the impedance conversion and preamplifier circuits incorporate German-made WIMA film capacitors, a deliberate choice to pursue extreme performance. These components leverage their inherent physical properties to guarantee pristine signal purity at the initial stage of transduction, laying a robust foundation for subsequent processing and high-fidelity recording. The output section adopts a transformer-less configuration, utilizing Japanese-made Rubycon electrolytic capacitors for coupling and DC blocking

The included accessories are streamlined but purposeful: an all-metal shock mount and windscreen. Crucially, these components are standard with the product, offering superior quality and performance compared to third-party alternatives. For users seeking optimal recording results, prioritizing these official accessories is advisable. Remarkably, the accessories match the microphone’s build quality, materials, and finish, reflecting Alctron’s philosophy of treating every element—whether core hardware or peripherals—as part of a cohesive, uncompromised system.

Core Technical Specifications & Practical Implications

The table below outlines the CX5’s technical specifications. I will analyze their real-world impact to contextualize the essence of these parameters.

The CX5 features a 34mm gold-spattered large diaphragm paired with a cardioid polar pattern (see diagram below). This combination forms the physical basis for its sonic signature. Large diaphragms typically deliver broader frequency response and richer low-end reproduction, while cardioid directionality effectively rejects ambient noise from the sides and rear, making it ideal for solo recording in non-ideal acoustic environments.

As illustrated, sensitivity peaks at 0° (front-axis), ensuring optimal sound capture. Side rejection (90°/270°) is approximately -6dB, necessitating positioning within 0°–60° of the sound source to avoid tonal inconsistencies. Rear rejection (180°) exceeds -20dB, making it adept for scenarios requiring isolation from background noise, such as studio vocals/instruments, stage performances, podcasts, or interviews.

The 20Hz–20kHz range encompasses the entire audible spectrum. Below is the frequency response curve.

The low-end exhibits a +3dB boost from 30Hz to 50Hz, enhancing warmth and fullness. However, proximity effect may cause bass overemphasis at close range. The midrange (200Hz–4kHz) remains flat within ±3dB, ensuring natural reproduction of vocals and instruments. A subtle lift in the 80–400Hz range adds "body", while a +3dB bump at 2–5kHz improves clarity and presence, aiding speech intelligibility without harsh sibilance. Highs rise gradually after 8kHz, peaking at +7dB near 18kHz for airiness, followed by a smooth roll-off to tame extreme frequencies. Based on listening tests (detailed later) and comparisons with peer products, this tuning prioritizes balanced practicality over exaggerated character.

Sensitivity (-38dB ±3dB):
High sensitivity ensures robust output levels even with modest preamp gain, reducing demands on entry-level audio interfaces. However, it also amplifies ambient noise (room reverb, HVAC systems), necessitating quieter recording environments.

Output Impedance (100Ω):
This value sits optimally within the professional standard range (50Ω–200Ω). It balances noise rejection, load-driving capability, and compatibility with virtually all pro audio gear (interfaces, mixers, preamps featuring >1,500Ω input impedance per impedance-matching principles).

Equivalent Noise Level (16dB-A):
An exceptional figure for a budget LDC microphone, meeting professional SNR requirements. The ultra-low self-noise preserves dynamic headroom and avoids audible interference, rivaling costlier models. This shatters the "entry-level = noisy" stereotype, elevating core performance.

Maximum SPL (137dB @ 1kHz, 1% THD):
Class-leading headroom accommodates aggressive vocals, acoustic instruments, and high-SPL sources. Practical for studio/stage applications requiring proximity to loud sound sources.

Subjective Listening & Multi-Scenario Application Analysis

Vocal Recording (Pop Male/Female):
