10.7. Digital Clock Configuration
10.7.1. Digital Clock Overview
In order to provide a flexible and robust audio processing system, the device is equipped with a configurable digital
clocking system. The digital clock can generate various independent internal sample rates, or can sync to an
incoming AES3 signal. Figure 10.7 shows the various sample rates and options available.

Table 10.7: Digital Clocking System
In Figure 10.7, each circled C represents a choice point. A choice point is a user-interface control that can be
configured using the Lake Controller software. Please refer to the Lake Controller Operation Manual for further
information.
Note: Figure 10.7 indicates internally generated clocks with base-rate multiples of 44.1 kHz or 48 kHz.
This should not be confused with the internal DSP sample rate of 96 kHz.
The PLM+ digital clocking system can either generate its own internal clock, or synchronize to an incoming
external clock source via the AES3 digital input.
