CONTROLS & CONNECTIONS 2.1 FRONT PANEL LAYOUT • Instrument Inputs (Channels 1 and 2). The ¼” TS connector on channels 1 and 2 are for use with an instrument (guitar, bass, etc.). When an instrument is plugged into the instrument input, the microphone preamp is bypassed, and the DigiMax D8 becomes an active instrument preamplifier. NOTE: Active instruments are those that have an internal preamp or a line level output. Active instruments should be plugged into a line input rather t

OPERATION 3.1 MICROPHONES The DigiMax D8 works with all standard microphones including dynamic, ribbon and condenser microphones. 3.1.1 Condenser Condenser microphones tend to generate a high-quality audio signal and are one of the most popular mic choices for today’s studio recording applications. Because of their design technology, condenser microphones require a power source, which can be provided from a small battery, external power supply or from microphone inputs as phantom po

OPERATION 3.2 DIGITAL CONNECTIONS AND SYNCRONIZATION 3.2.1 ADAT Optical Lightpipe ADAT is an industry standard abbreviation for the ADAT Lightpipe protocol, which transfers eight tracks in a single fiber optic cable. Supported sample rates are 44.1 kHz and 48 kHz. When you are utilizing the eight DigiMax D8 preamplifiers and converting to the digital optical output, connect one ADAT optical cable from the ADAT output on the back of the DigiMax D8 to the ADAT optical input on your d

OPERATION 3.2.3 Master/Slave and Multiple Digital Devices Whether you are using the ADAT output of the DigiMax D8 to generate word clock or you are using the BNC word clock output of another device as your word clock generator, it is necessary to denote one device as the “master” word clock device to which all other digital devices are synced or “slaved”. The DigiMax D8 should perform equally well as a master or a slave in most cases, although syncing it to a lesser quality clock source

OPERATION 3.3.2 Using multiple DigiMax D8 with the FireStudio LightPipe The DigiMax D8 is a great low cost solution to expand your FireStudio LightPipe for live or mobile recordings where a large number of simultaneous inputs are needed and two track output is enough for monitoring. To clock more than one DigiMax D8 to the same external sync you will need a BNC T-Connector for each DigiMax D8 you are connecting to your system. This is called parallel clock distribution and will allow wo

OPERATION 3.3.3 Using the DigiMax D8 to Add Preamps to a Multiple Line Level Input Device The inputs of many audio interfaces and mixers are blended between microphone preamps and line level inputs. Balanced ¼” inputs are a great way to conserve space. Because of its direct analog outputs, the DigiMax D8 can also be used to add preamps to devices of this nature. It is important to note that when connecting two digital devices with an analog connection it is not necessary to use word clo
