TASCAM has introduced a new field recorder, the FR-AV4, positioning it as a competitor to established models like the Sound Devices MixPre series and the Zoom F6. This article explores the features, performance, and value of the FR-AV4 to help users evaluate its potential fit within different workflows.
Build and Feature Overview
The FR-AV4 features a metal housing, HDMI 2.1 ports for audio embedding in video signals, and a built-in timecode generator. Its battery efficiency is notable, with testing showing longer runtime on AA batteries than some competing devices. HDMI input/output and unit-linking capabilities are among its distinguishing attributes.
Feature Tradeoffs
One notable omission is an automix function, which is available on competing devices. This may be a key factor for users requiring hands-off audio level balancing. In terms of pricing, the FR-AV4 sits between the MixPre-3 II and MixPre-6 II, but is priced higher than the Zoom F6.
Initial Audio Comparisons
Audio samples were recorded using the FR-AV4, MixPre-3 II, and Zoom F6 with a Sennheiser MKH50 microphone. All samples were normalized to -23 LUFS without additional processing to highlight each recorder's raw audio characteristics. This provided a clear comparison of native sound quality.
Detailed Specifications and Capabilities
The FR-AV4 is a 32-bit float recorder with dual converters on each of its four XLR combo inputs, supporting both mic and line-level signals. Maximum input levels are +4 dBu for mic and +24 dBu for line. The stated dynamic range is 133 dB, and equivalent input noise is -127 dBu. Testing confirms low self-noise levels, emphasizing the importance of managing microphone and environmental noise.
Digital limiters, EQ, and noise gates are available per input channel. The unit records six tracks simultaneously (four inputs and a stereo mix) at selectable sample rates of 48, 96, or 192 kHz. It also features a 20-second file-saving interval to prevent significant data loss during power interruptions.
Timecode and Synchronization
The built-in timecode generator uses a temperature-compensated crystal oscillator rated for minimal drift within a 0 to 40°C range. Use in freezing temperatures may affect timecode accuracy, as the oscillator is not designed for sub-zero conditions.
Connectivity and Power
The FR-AV4 includes two HDMI 2.1 ports (in and out), supporting up to 8K video passthrough and enabling multiple unit synchronization. Additional ports include 3.5mm stereo input/output and USB-C, which supports audio interface functionality at 32-bit float (up to 96 kHz).
Power options include four AA batteries, USB-C, or external battery banks. With Ikea Ladda 2450mAh batteries and phantom power enabled on one input, the FR-AV4 operated for over seven hours, outperforming several competitors in similar conditions.
Interface and Optional Enhancements
The 1.9-inch touchscreen is responsive and well-lit. An optional AK-BT2 Bluetooth adapter adds features like timecode sync with Atomos devices, remote app control, and Bluetooth headphone monitoring (with expected latency). The unit also supports ambisonic recording in A and B formats and includes a tone generator for camera calibration and up to 300ms of output delay.
Routing controls are intuitive, offering flexible input selection and monitoring configurations.
Limitations and Considerations
The absence of an automix function differentiates the FR-AV4 from competitors like the Zoom F6 (which includes one) and the MixPre series (MixAssist available via plugin). Additionally, the headphone amplifier produces some noise and has less output power compared to rivals, which may impact monitoring clarity.
At approximately $1,000, the FR-AV4 is priced higher than the Zoom F6 and roughly on par with the MixPre-3 II and MixPre-6 II.
Comparative Build Quality and Use Cases
The FR-AV4 has a sturdy metal build. Its plastic knobs are comparable to the Zoom F6, while the MixPre offers more refined controls. Standard ¼-inch mounts support tripod or camera rig integration.
FR-AV4 vs. Zoom F6:
Advantages include dedicated timecode ports, HDMI support, EQ/noise gate per input, and efficient battery use. The F6, however, offers six XLR inputs, automix, better headphone output, and broader power options, at a lower price point.
FR-AV4 vs. MixPre-3 II:
The FR-AV4 provides dedicated timecode ports, a larger touchscreen, Bluetooth monitoring, and advanced EQ/noise gate features. The MixPre counters with MixAssist, more flexibl
