Frequently Asked Questions - SAT-2 Radial Engineering
What is the Radial SAT-2 and what is it used for?
The Radial SAT-2 is a passive direct box with two independent channels, designed to connect unbalanced instrument or line-level signals to balanced mixer inputs. It is commonly used in live sound and recording to eliminate noise and match impedance.
Does the SAT-2 require external power?
No, the SAT-2 is completely passive and does not require batteries, phantom power, or any external power source. It uses internal audio transformers for signal conversion and isolation.
Can I use the SAT-2 for stereo signals?
Yes, the SAT-2 has two channels that can be used independently for dual mono or as a stereo pair. Make sure to use both inputs and outputs accordingly.
What is the ground lift switch for?
The ground lift switch disconnects the input ground from the output ground to break ground loops, which can cause hum and buzz. Use it if you hear unwanted noise after connecting the device.
How do I use the attenuation pad?
The -15 dB pad reduces the input signal level by 15 dB. Engage it when connecting high-level line sources (e.g., synthesizers, audio interfaces) to prevent distortion.
What type of cables do I need?
For inputs, use standard 1/4 inch TS cables (instrument or line cables). For outputs, use XLR male cables to connect to a mixer or audio interface.
Is the SAT-2 suitable for passive guitar pickups?
Yes, the SAT-2 is ideal for passive electric guitars and basses. It converts the high-impedance unbalanced signal to a low-impedance balanced signal, preserving tone over long cable runs.
Can I use the SAT-2 in a studio recording setup?
Absolutely. Its transparent transformers and low noise floor make it suitable for both live and studio environments. Use it to feed signals directly into microphone preamps.
How do I clean and maintain the SAT-2?
Wipe the exterior with a dry, lint-free cloth. Do not use liquids or cleaning agents. Ensure connections are free from dust and moisture. No internal maintenance is required.
What should I do if my SAT-2 stops working?
First, check cables and connections. If the issue persists, contact Radial Engineering support or an authorized service center. Do not open the unit as it contains no user-serviceable parts.
