Designed with a **1.5-inch (38mm) ribbon element**, this microphone delivers an unparalleled blend of warmth, detail, and dynamic response, making it an ideal choice for capturing vocals, acoustic instruments, and ambient soundscapes with exceptional precision. Its **figure-8 (bidirectional) polar pattern** ensures that sound is picked up from the front and rear while rejecting off-axis noise, allowing for clean isolation in complex recording scenarios whether you're tracking a solo voice, a duet, or a layered ensemble. The microphone s **passive design** eliminates the need for phantom power, relying instead on a robust internal transformer and high-quality components to drive its output, resulting in a clean, uncolored signal that remains true to the source.
Constructed with **durable, high-grade materials**, the BIV-1 features a **black anodized aluminum body** that not only enhances its aesthetic appeal but also provides structural integrity and resistance to wear. The **detachable, shock-mounted capsule** is housed in a protective cage, ensuring stability and minimizing handling noise, while the **3-pin XLR output** delivers a balanced, low-noise signal ready for direct connection to preamps, mixers, or audio interfaces. The microphone s **frequency response**, spanning from **20Hz to 15kHz**, offers a naturally extended low-end and a smooth, extended high-end, ideal for capturing the nuances of vocals, strings, brass, and even room ambience with remarkable fidelity. Whether used for studio recording, podcasting, or live performance, the BIV-1 excels in environments where clarity and tonal depth are paramount.
For those seeking versatility, the BIV-1 s **figure-8 pattern** allows for creative positioning whether placed in front of a singer to capture a full, open sound or positioned behind an instrument to isolate its natural resonance. Its **low output impedance** ensures compatibility with a wide range of preamps, while its **passive circuitry** contributes to a clean, distortion-free signal even at high SPL levels. The microphone s **minimalist yet robust build** makes it equally at home in a professional studio or a home recording setup, offering studio-grade performance without the complexity of active electronics. Whether you're a producer refining a vocal take, a sound engineer capturing a live performance, or a musician seeking the perfect tone for their recordings, the Pure BIV-1 BASH Audio RM Figure-8 Passive Ribbon Microphone stands as a testament to craftsmanship and sonic excellence.
The **Bash Audio RM Figure-8 Passive Ribbon Microphone** is a unique and highly regarded ribbon mic, particularly for its figure-8 polar pattern, which offers both proximity effect and a natural, smooth sound. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros of the Bash Audio RM Figure-8**
1. **Exceptional Sound Quality**
The RM is widely praised for its warm, smooth, and detailed audio reproduction. It excels in capturing vocals, acoustic instruments, and ambient sounds with a rich, natural tone. The ribbon element delivers a smooth high-end rolloff and a gentle midrange presence, making it ideal for vocal recording, guitar amps, and room mics.
2. **Figure-8 Polar Pattern**
The figure-8 pattern allows for creative recording techniques, such as:- **Blending two mics** (one on-axis, one off-axis) to reduce plosives or achieve a balanced sound.
- **Isolating a single sound source** while rejecting others (e.g., recording a vocal with the mic facing forward and the room noise rejected from the back).
- **Ambient recording** by placing the mic in a room and capturing reflections from both sides.
3. **Passive Design with Low Output**
The passive ribbon element requires a preamp with sufficient gain, which can be an advantage for engineers who prefer to control the signal chain. It also means the mic is less prone to distortion from high SPL (sound pressure levels) compared to some active ribbon mics.
4. **Durability and Build Quality**
The RM is built with a sturdy metal body and a robust shock mount, making it suitable for live and studio use. The ribbon itself is designed to handle moderate SPL levels (up to 140 dB), though extreme levels may still risk damage.
5. **Versatility**
Beyond vocals and instruments, the RM can be used for:- **Room mics** (capturing natural reverb).
- **Guitar amps** (especially for a smooth, vintage tone).
- **Podcasting** (when paired with a pop filter or treated environment).
- **Field recording** (for ambient soundscapes).
6. **Affordability Compared to Competitors**
While high-end ribbon mics (e.g., Royer R-121, Coles 4038) can cost significantly more, the RM offers comparable performance at a lower price point, making it an attractive option for budget-conscious buyers.
7. **Minimal Phase Cancellation**
Unlike some cardioid mics, the figure-8 pattern avoids phase cancellation issues when used in stereo pairs or with multiple mics, provided proper placement is maintained.
8. **No Power Supply Needed**
Being passive, the RM doesn t require phantom power, reducing the risk of electrical interference in some setups.

### **Cons of the Bash Audio RM Figure-8**
1. **Requires a Strong Preamp**
The RM s low output level means it needs a high-gain preamp to reach usable levels. This can be a drawback for users with weaker audio interfaces or preamps, as they may struggle to achieve clean, loud recordings without excessive noise.
2. **No Built-in Pad or Low-Cut Filter**
Unlike some ribbon mics (e.g., the Coles 4038), the RM lacks a built-in pad (-15 dB) or high-pass filter. This means users must rely on their interface or mixer to control gain and reduce low-end rumble, which can be inconvenient for live recording or untreated environments.
3. **Sensitivity to Handling Noise**
Ribbon mics are generally fragile, and the RM is no exception. The ribbon element can be damaged by rough handling, strong magnetic fields, or excessive SPL. Users must handle it with care and avoid dropping it.
4. **Limited High-SPL Handling**
While the RM can handle up to 140 dB, it is not designed for extreme SPL environments (e.g., loud live drums or screaming vocals). In such cases, a pad or additional gain reduction is necessary to avoid distortion or damage.
5. **No Onboard Controls**
The RM has no adjustable elements (e.g., no switchable patterns or gain stages), meaning all settings must be managed externally. This can be less convenient than mics with onboard controls.
6. **Not Ideal for All Vocal Styles**
While the RM excels with smooth, mid-range vocals (e.g., acoustic guitar, soft singing), it may lack the punch or clarity needed for harsh or high-gain vocal styles (e.g., metal, rap). Some users prefer a cardioid mic for these applications.
7. **Requires Proper Placement for Optimal Results**
The figure-8 pattern demands careful positioning to avoid uneven sound capture. For example, recording a vocal with the mic off-axis can introduce unwanted coloration or phase issues if not managed properly.
8. **No Built-in Shock Mount (Requires Purchase Separately)**
While the RM comes with a basic shock mount, some users may prefer a more robust or customizable mount (e.g., from Aton or sE Electronics), which adds to the cost.

### **Conclusion**
The **Bash Audio RM Figure-8** is one of the best-value ribbon mics on the market, offering professional-grade sound quality at a relatively affordable price. Its figure-8 pattern opens up creative recording possibilities, and its smooth, warm tone makes it a fantastic choice for vocals, acoustic instruments, and ambient recording. However, its passive nature means it requires a strong preamp, and its fragility demands careful handling.
This mic is **ideal for**:- Home studios looking for a high-quality ribbon mic without breaking the bank.
- Engineers who value the figure-8 pattern for blending mics or capturing natural sound.
- Vocalists and instrumentalists who prefer a smooth, vintage tone.
- Ambient and field recordists who want a versatile tool for capturing space and reflections.
It is **less ideal for**:- Users with weak preamps or interfaces that struggle with low-output mics.
- Those who need a mic for high-SPL environments without additional gain reduction.
- Performers or live sound engineers who require durability and ease of use in rough conditions.

**Final Verdict:**The RM is a **fantastic entry-level to mid-range ribbon mic** that delivers professional results. If you can invest in a **high-quality preamp or audio interface** (e.g., Focusrite Scarlett, Universal Audio 610, or a dedicated preamp like the Warm Audio WA76), the RM will thrive. For most home studios and creative recording setups, it is a **highly recommended purchase**.
