Hi,
I searched for troubleshooting tips on this but didn't find anything. Here is what I am running:

Lubuntu 13.04
Ardour 3.5.357
JACK 0.3.9
Mixer A&H ZED60- 14FX

Even when I have the input level on the mixer maxed, the level recorded through Ardour is very low.

I checked alsamixer. I made sure all of the capture devices were at least 75%. I am not sure which capture device in alsamixer is actually the USB device.

I also verified that the input level on the Ardour mixer is 75%.

What else can I check?

Thanks for your help.

Hi, jbird. Check your User manual!
Its Important.

What are you recording? Line signal, or Mic?
Line = E-Bas, E-Git, Keys...... MIc = Microphone :) Levels arent same!

Can you see/find that A&H USB device on your Lubuntu? (start terminal and type: lsusb, press enter :)
How its labeled?

0. Plug your mic into chanel. Check 48V to Mics (phantom power): If you use condenser mic, must be ON. ( its ONE BUTTON for all chanels also in master section)

0.1 set your gain! Hmmmmmmmmmmmm...... USB interface 16 bit max and 48 KHz ; you ll need some nice expander/gate
( real device, not plugin :)

A&H labeled an " Listen " button (? ) in every chanel, you press it and than set the levels in PFL ( watch meter levels in master section, DONT GO RED, you have 16 bit and max 48 Khz only :) After setting that level you must depress ( UP) that Listen button.

1. check Record button in that chanel you record ( press it down and ZED is sending signal over its internal bus direct to its internal USB audio Card ( USB port in ZEDĀ“s master section)
MAASTER fader is at 0 dB!

2. Press RECORD button in master section for HP monitor of recording, now you re going to record that chanel direct into daw ( Ardour)

3. find in ardours CH inputs either zeds L or R chanel.

Monitoring? over HP, over main Monitors, listening send or return ( tape send, or tape return)
I gave you some idea, now... go ahead.

Make some noise :)

first check the routing, the usb audio outs according the a review i read can be fed from Master L+R, auxilary or the headphone control. So check that

Thanks all. You comments were helpful. Things are working better now. Honestly, I am sure what the fix was. I am able to get a decent signal into Ardour now.
