Apollo Thunderbolt Software Manual Console Reference 86
Polarity
When enabled, the polarity (aka “phase”) switch is yellow and the input
channel’s signal is inverted. Polarity affects the Mic, Line, and Hi-Z
inputs.
Tip: Polarity inversion can help reduce phase cancellations when more than one
microphone is used to record a single source.
Reference Level (Apollo, Apollo 8, Apollo 16)
The signal reference level for analog line inputs
without preamps can be switched between -10 dBV
and +4 dBu. Click the display to toggle the setting.
The setting controls an attenuation pad for the
input channel. When set to +4 dBu, the pad is engaged and the channel can accept a
higher signal level before the A/D converter clips. Select -10 dBV when lower input signal
levels are used.
Tip: To adjust signal incoming levels for Apollo’s analog inputs that don’t have
preamps, use the output level controls of the devices that are connected to those
inputs.
Tip: Additional gain can be added to input signals by inserting UAD plug-ins and
adjusting the gain structure within the plug-ins.
The availability and behavior of the reference level control depends on the hardware
model, as described below.
Apollo – The reference level for analog input channels 5 & 6 and 7 & 8 are linked
in Apollo’s hardware. Therefore, the reference level in Console can only be switched
according to these stereo pairs.
Apollo 8 – The reference level for analog input channels 5 – 8 can be individually
switched.
Apollo 16 – The reference level for all analog input channels 1 – 16 can be individually
switched.
