7 Troubleshooting & User Tips
Q. After driver installation, the Hilo does not appear to the OS as an active device
A. Check the following:
* Make sure that the Operating system is compatible with Hilo/TB
* If used with a Windows computer, make sure that the Thunderbolt chipset drivers for the motherboard have been
installed. See the manufacturer’s support resources for details
* Verify that the Hilo has firmware revision 6 or above (from ABOUT HILO on the Information page)
* Make sure that the Thunderbolt cables are seated correctly on both ends
* Try the other Thunderbolt port on the Hilo, as well as a different Thunderbolt port on the computer if applicable
Q. When I change my Sync Source or Sample Rate on the Hilo, I get distortion on the outputs.
A. Make sure that any audio applications are closed when changing Sync Source or Sample Rate. Insure that the
Sample Rate in the audio software matches the Sample Rate of the Hilo.
Q. What does the white box around the Input Source mean?
A. That means that that Input is in “Focus”. In other words, the Input Level Fader, Metering and ON/OFF state are for
that selected (Focused) input. This is useful since you may have multiple Inputs feeding an Output and may want to
check levels, etc. for one of them.
Q. I have multiple sources coming into Hilo and they are all mixing onto the same tracks in my DAW.
A. In the OUTPUT MIX ROUTING PAGE, select the Output (e.g. TBT REC 1 &2) and make sure you do not have
any unwanted Inputs being routed to that Output. To turn off an Input, tap the ON button so it becomes a red OFF or
you can tap the Input (once if it is already in “Focus” or twice if it is not) until it turns red.
Q. My monitor level (or phones) is turned up but the audio is still very low.
A. Check the Input Level for the Inputs feeding that Output and make sure they are at a sufficient level. Also, for
MONITOR OUT and PHONES, tap the “Analog” button (at the bottom of the Outputs field) to switch it to the Digital
Level, and make sure that level was not turned down.
Q. My output level is turned down but the audio is distorted.
A. Check your Input Levels to your selected Output. The Input Source Level has the ability to be raised higher than “0”
level and thus can add gain that may distort your output.
Q. I am mixing Inputs to my Monitors (or Phones) and the Output is distorting. I like the mix of the Inputs and I do not
want to have to turn down each Input one at a time. What can I do?
A. Tap the “Analog” button (at the bottom of the Outputs field) to switch it to the Digital Level. This is the digital
output level before it feeds the analog MONITOR and PHONES. Bring the Digital Level down until you are not hitting
the “Overs” on the Output Meters.
Q. When do I use the Sample Rate Converter?
A. There are two situations where you would the SRC:
1) When your digital inputs to Hilo are coming in at a sample rate that differs from the sample rate of Hilo. Hilo will
up-or-down sample the input signal to match itself and
2) If your digital sources are coming in at the same sample rate as Hilo, but your digital sources have no ability to clock
slave to Hilo (e.g. consumer CD players). The SRC will re-clock the digital input signal to make sure it is in Sync with
Hilo’s clock.
