I'm reading this with great interest, and the discussion about dBu/dBFS got me to look up teh specs of my interface (Lexicon Lambda). So, for this to make more sense to me... could someone please explain what the "Maximum Input Level" and output levels below really mean in relation to Reapers metering? Thanks.

Code:
Microphone Inputs	(2) Female XLR Pin 2 Hot
Input Impedance		600 ohms balanced
Phantom Power		+48 Volt
GAIN			+44 dBu
EIN			-115dB A-weighted @44dB gain (150 Ohm source impedance)
Maximum Input Level	+6.5dBu
Frequency Response	+0, -0.5 dB 20 Hz - 20 kHz, ref. 1 kHz
THD+N			<.005%, 20 Hz - 20 kHz

Insert Inputs:		        (2) 1/4" TRS
Send Level (tip):		+10 dBu maximum
Maximum Return Level (ring)	+11 dBu maximum

Line Inputs		(2) 1/4" TRS balanced or unbalanced
Input Impedance		20 kOhm balanced, 10 kOhm unbalanced
Maximum Input Level	+13 dBu
Frequency Response	+0, -0.5 dB 20 Hz - 20 kHz, ref. 1kHz
THD+N			<.009% A/D, 20 Hz - 20 kHz

Instrument Input	(1) 1/4" mono jack
Input Impedance		1 MOhm unbalanced
Maximum Input Level	+8.5 dBu
Frequency Response	+0, -1 dB 20 Hz - 20 kHz, ref. 1 kHz
THD+N			<.0125% A/D

Line Outputs		(2) 1/4" TRS balanced or unbalanced
Level			+16 dBu maximum
Impedance		1 KOhm

Headphone Output	(1) 1/8" stereo jack 25 mW per channel at 50 Ohms

MIDI Interface		5 pin DIN connectors for MIDI in and MIDI out
Sample Rate		44.1 kHz or 48 kHz (determined by computer application)
Dynamic Range		A/D (24 Bit) 104 dB typical, A-weighted, 20 Hz - 20 kHz
			D/A (24 Bit) 96 dB typical, A-weighted, 20 Hz - 20 kHz
A/D/A (24 Bit)		100 dB typical, A-weighted, 20 Hz - 20 kHz
