Designed in Canada, Ready for the World
Built to work with Phoenix sensors and EMpower software, MTU-5C, MTU-8A, and RXU-8A receivers are designed to survive life in the field and provide excellent geophysical results.
50 years of equipment design and field experience come together at Phoenix to make our receiver systems high-performance, simple, and rugged– doing their job so you can do yours, wherever you need to go.
Quality Control and Live Data Access
The bright screen on every Phoenix receiver shows what’s going on right in the field -without needing any other device- to make sure everything is connected, ready, and working.
MTU-5C systems also provide live access to all time series on the internal SD card: no internet connection required. With the Data Share function, Field QC and data retrieval can be done without interrupting acquisition, from the ethernet port.
​
Automatic system and recording diagnostics, in-field calibration capability, and extensive metadata ensure proper logging of system performance and field operations.
Easy Configuration and Easy Operation
Configuration files on the SD card set all receiver parameters from decimation rates to filter settings. New config files take just seconds to make using EMPower’s visual Config Creator.
Single-button start means field crew can focus on field operations not data entry, helping to avoid mistakes and keep crews moving.
Up to 8 independent channels with their own gain, filter, and sensor type settings provide maximum flexibility, and with no adaptors or separate sensor power supplies required, equipment layout is intuitive and clear.
​
From early 2025, all new MTU-5C systems also support Galileo and BeiDou, providing improved location data and ensuring compatibility with local requirements.

Designed to work with Phoenix sensors, MTU-5C, MTU-8A and RXU-8A connect directly to MTC-155 and MTC-185 broadband coils, with increased dynamic range. Older MTC-150, MTC-180, MTC-50H, MTC-80H, and AMTC-30 sensors also connect directly, with no adaptors, splitter cables, or additional power supply required.
Two Paths to Broadband
Using MTC-155/185 sensors, Phoenix receivers record the entire spectrum from 10kHz down to thousands of seconds. MTU-8A has 6 magnetic inputs, allowing an alternative path to 10kHz-10ksec broadband by connecting a full set of three MTC-50H and three AMTC-30 sensors at the same time.
Works with Phoenix Sensors
Fluxgates Supported
MTU-5C, MTU-8A and RXU-8A work directly with Bartington Mag13-MS70, Bartington Mag03MSES70, and LEMI-039 fluxgate sensors, enabling more efficient long-period measurements. EMpower also supports configuring these fluxgates and correctly processing their results.
Connected Everywhere
With built-in ethernet networking and simple network configuration, every Phoenix receiver can upload data to a remote server by cellular or satellite modem. Want remote station data at the base camp before heading to the site in the morning? Phoenix systems let you do that.
In a fully-connected survey, all data quality decisions can be made –and made with the benefit of remote reference processing– before a crew even goes out to the field in the morning, improving QC, reducing unnecessary repeats, and eliminating data transfer and evaluation by the operating crew.
Once uploaded, the time series can be immediately and securely shared with clients, consultants, and geoscientists back at the office for review, planning and backup.
​
In addition to remote network acess, the ethernet port also provides live access to all files on the receiver's internal SD card when the Data Share function is enabled.
Powerful and Power Efficient
Phoenix receivers offer selectable data sampling rates from full-rate 24ksps recording that generates about 1GB/hour all the way down to sparse high frequency sampling outputting 10MB/hour (0.01GB/hr), with typical settings generating about 1GB of data per overnight 5-component recording.
This allows users the option of full-rate recording to capture every high frequency event during the acquisition time, or optional progressive levels of sparse sampling decimation to reduce file sizes and data transfer requirements.
At about 1 Watt per channel, Phoenix receivers are the most power-efficient true broadband systems available. Able to run for days on a normal car battery, they also allow inputs from 10.8V to 14V, making it easy to use more modern batteries.
Massive Storage
With standard 64GB of removable storage and support for SD cards up to 512GB, Phoenix receivers are able to record more than 500 days of normal 5-channel MT timeseries, and 2000 days using the long-term sparse sampling mode.
Incredibly rugged and reliable, SD cards are rated to –25C / 85C, shock and impact resistant, waterproof, and x-ray proof. They are also highly compatible, fast, and supported card types are readily available at reasonable cost.

Easy Diagnostics & Maintenance
With simple tools and easy-to-follow assembly guides for end-user maintenance, all connectors, buttons and data acquisition channels user replaceable in about 30 minutes. ANG02 and Receiver Test Kit are essential companions for users doing their own front-line maintenance.
Thousands of Systems Sold to 100+ Countries
Since 1997, Phoenix has delivered thousands of MTU systems to users in over 100 countries. Like earlier systems, MTU-5C/8A receivers have worked on every continent, including Antarctica.
