Linear Acoustic UPMAX v4 User Guide Detailed Operation
21
4.5.12 Downmix LFE Level
Controls the level which the LFE channel is attenuated and included in the downmix. This
parameter allows the downmix to contain LFE information for a little extra “punch” when
desired.
NOTE: When emulation of a consumer device is desired, this parameter should be set to “OFF”
4.5.13 7/8 in Channel Mode
Selects the audio mode for inputs 7/8. Selections include: Stereo, Mono, Mono Ch1, Mono
Ch2
4.5.14 SRC Bypass
Selects whether input audio is passed through Sample Rate Converters before processing.
Input audio can be either a different sample rate (44.1 kHz) or more typically is a different
clock reference than the output audio. Unless the input and output audio are known to
synchronous, SRC Bypass should be set to “OFF” (SRCs in the path)
4.5.15 Headphone Boost
Enables or disables a 10 dB boost at the headphone output.
4.5.16 Clock Source Type
Selects whether the reference clock source a stable source or a changing source
4.5.17 Clock Source
Selects the output reference source for the unit. Selections include: Internal 48kHz (de-
fault), AES 1, and SDI.
NOTE: All inputs pass through audio frame synchronization (SRCs) whose output is determined by the clock
setting. Inputs of many different sample rates can be accommodated, but reference must be from a 48kHz
source. Good clocking practices are strongly encouraged!
4.5.18 Audio Input Sources (Channels 1-8)
Selects between applied AES audio or audio de-embedded from SDI. Each of the input
pairs 1/2, 3/4, 5/6, and 7/8 can be sourced from its corresponding AES input pair or any
