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 than into an instrument input. Plugging a line level source into the instrument inputs on the front of the DigiMax D8 not only risks damage to these inputs but also results in a very loud and often distorted audio signal.

(In other words, don’t plug a line level source into the front panel jacks of channel 1 or 2.)

•-20 dB Pad. These buttons attenuate the input signal on each channel by 20dB. The pad can be used to keep a hot signal from overdriving the microphone preamp.

•Input Gain/Trim Control. These knobs provide the following gain structure:

oXLR Microphone Inputs. 54dB of variable gain (-4 dB to +50 dB)

oTS Instrument/Hi-Z Inputs (Channels 1 & 2 only). 54dB of variable gain (-4dB to +50dB)

•LED Meters / Clip Indicator. Each channel features four LED level indicators. The green LEDs will light up when your input signal from the XLR (Mic) or ¼” (Hi-Z Channels 1&2 only) reaches -24 dBFS and -18 dBFS respectively. The yellow LED will light up when the channel’s input signal reaches -6 dBFS (+4 dBu). The red clip indicator LED will illuminate when the channel’s input signal reaches 0 dBFS. At this level, your mic preamp trim signal will exhibit signs of clipping such as distortion. It is highly recommended you do not allow your converters to clip (the red clip indicators to light up) as the sound quality will not be desirable. If you are having difficulty achieving a useable signal level without clipping, engage the -20 dB pad.

Digimax 8 Channel Preamplifier with 24 bit/48 kHz ADAT out, D8 specifications

The PreSonus Audio Electronic D8 is a versatile and powerful audio interface designed to cater to the needs of musicians, podcasters, and audio professionals alike. Renowned for its exceptional sound quality and robust feature set, the D8 serves as an excellent bridge between analog audio sources and digital recording environments.

One of the standout features of the D8 is its 8-channel input capability. This allows users to connect multiple microphones and instruments simultaneously, making it perfect for recording ensembles, bands, or multi-instrument setups. Each channel is equipped with high-quality microphone preamps, which ensure that audio is captured with clarity and detail. The preamps are designed to deliver a transparent sound, enabling users to maintain the true character of their audio sources.

The D8 also incorporates advanced ADAT (Alesis Digital Audio Tape) optical inputs, allowing for easy expansion. This feature is particularly beneficial for studios looking to integrate additional devices or expand their recording capabilities. With the ADAT connection, users can daisy-chain other audio interfaces or digital mixers, significantly increasing channel count without compromising audio fidelity.

In terms of connectivity, the D8 offers USB 2.0 compatibility, ensuring seamless integration with various digital audio workstations (DAWs) on both Windows and macOS platforms. The plug-and-play feature simplifies the setup process, allowing users to focus on creativity rather than technical configurations.

Another key characteristic of the D8 is its low latency performance. This is crucial for musicians who rely on real-time monitoring while recording, as it minimizes any delay between recorded sound and playback, enhancing the recording experience and allowing for precise timing.

The unit is housed in a rugged chassis designed to withstand the rigors of the studio and live environments. Its compact, portable design makes it an excellent choice for mobile setups, ensuring that professionals can take their audio recording capabilities anywhere.

Additionally, the D8 includes comprehensive software bundles, providing users with tools for mixing, editing, and processing audio, further enhancing its value as an all-in-one solution for audio production. With its combination of features, sound quality, and ease of use, the PreSonus Audio Electronic D8 stands out as a reliable choice for anyone looking to elevate their audio recording experience.
