Frequently Asked Questions - Track One Mk3 SPL
What type of power supply does the Track One Mk3 use?
The device has an internal power supply that can be switched between 115 V and 230 V AC, 50-60 Hz. Always ensure the voltage selector matches your local mains voltage before connecting.
How do I connect a microphone to the Track One Mk3?
Connect your microphone to the XLR input on the rear panel. For condenser microphones, press the +48V phantom power switch. Adjust the GAIN knob to set the input level.
Can I use the Track One Mk3 as a standalone DI box?
Yes, the instrument input (¼" TS) is designed for direct connection of electric guitars or basses. It has a high impedance (1 MΩ) to preserve the instrument's tone.
How do I adjust the equalizer?
The EQ section has three bands: LOW, MID, and HIGH. Each band has a FREQ knob to select the center frequency and a GAIN knob to boost or cut (±15 dB). The MID band also has a Q control for bandwidth.
How does the compressor work?
The compressor is an opto-type with controls for THRESHOLD, RATIO, ATTACK, and RELEASE. Adjust THRESHOLD lower to engage compression, set RATIO for the amount of gain reduction, and tweak ATTACK/RELEASE for timing.
What is the maximum output level?
The balanced XLR output can deliver up to +26 dBu into 600 Ω. This allows the unit to drive professional audio interfaces and console inputs with ease.
How do I clean the Track One Mk3?
Disconnect the power cord. Use a soft, lint-free cloth slightly dampened with water to wipe the front panel and enclosure. Do not use any chemical cleaners or abrasives.
What is the frequency response of the unit?
The frequency response is specified as 10 Hz to 200 kHz (-3 dB), ensuring very wide bandwidth suitable for high-resolution audio.
Does the Track One Mk3 have a sidechain input?
No, the Track One Mk3 does not include a sidechain input. The compressor's detection circuit is internal and keyed from the input signal.
