### **Cons of the APx6400-DGPS-0**
1. **High Cost**
The APx6400 is an **expensive investment**, typically priced in the **$15,000 $20,000 range** (depending on optional modules and accessories). This makes it inaccessible for:
- **Individual hobbyists or small studios** on a tight budget.
- **Educational institutions** without dedicated research funding.
- **Small businesses** that cannot justify the cost for occasional use.
For comparison, entry-level analyzers (e.g., **SoundCheck, TrueRTA, or even some software-based tools**) can cost **$1,000 $5,000**.
2. **Complexity for Beginners**
The APx6400 s **advanced features** (e.g., DGPS time sync, custom scripts, multi-channel setups) can be **overwhelming** for users without prior experience in audio measurement. Steep learning curves may require:
- **Training or documentation review** (though Audio Precision provides good resources).
- **Time to configure and troubleshoot** setups, which may slow down workflows for new users.
3. **Size and Portability**
The APx6400 is a **large, bench-top unit**, measuring approximately **17.5" x 14.5" x 10.5"** (445 x 368 x 267 mm). This makes it:- **Impractical for field testing** (e.g., on-site loudspeaker measurements).
- **Space-intensive** in labs or studios with limited bench space.
Portable alternatives (e.g., **APx555** or **SoundCheck Mobile**) may be more suitable for on-the-go use.
4. **Power and Infrastructure Requirements**
The analyzer requires:- A **dedicated power outlet** (not USB-powered).
- **Stable network connectivity** if used for time-synchronized measurements.
- **Proper grounding** to avoid interference in sensitive measurements.
This may not be ideal for **remote or mobile testing environments**.
5. **Learning Curve for Advanced Features**
While the basic frequency response and distortion measurements are straightforward, **advanced features** (e.g.,:- **Acoustic impulse response (AIR) measurements** with DGPS sync.
- **Custom scripting** for automated tests.
- **Multi-channel phase alignment**.
) require **significant time to master**. Users may need to consult manuals or seek training, which adds to the initial investment.
6. **Limited Built-in Microphone Inputs**
While the APx6400 can measure **electrical signals** with high precision, its **acoustic measurement capabilities** are limited without optional accessories. Users interested in **room acoustics or live sound testing** may need to purchase:
- **High-quality microphones** (e.g., **G.R.A.S., DPA, or Earthworks**).
- **Preamps and signal conditioners**.
This adds to the overall cost and complexity.
7. **No Built-in Oscilloscope or Spectrum Analyzer**
Unlike some multi-function analyzers (e.g., **Rohde & Schwarz, Tektronix**), the APx6400 **does not include an oscilloscope or spectrum analyzer** as standard features. While it excels at **time-domain and frequency-domain measurements**, users needing **real-time waveform visualization** may require additional tools.
8. **Software Dependency**
The APx6400 relies heavily on **AP Workbench**, which is a **Windows-only application**. This can be a limitation for users working in:- **Mac or Linux environments**.
- **Networked setups** where cross-platform compatibility is needed.
While virtualization or dual-boot setups can mitigate this, it adds complexity.
9. **Maintenance and Calibration**
High-precision instruments require **periodic calibration** to maintain accuracy. While Audio Precision provides calibration services, this adds to the **long-term cost of ownership**, especially for users who may not have in-house calibration expertise.
10. **Overkill for Basic Testing**
For users who only need **simple frequency response or distortion measurements**, the APx6400 s **full feature set may be unnecessary**. More affordable alternatives (e.g., **SoundCheck, TrueRTA, or even software-based tools like Audacity with plugins**) may suffice for basic tasks.
