MIDAS DP48 Dual 48 Channel Personal Monitor Mixer with SD Card Recorder
Introduction
Thank you for purchasing the DP48 Personal Monitor Mixer! The DP48 unit is
housed in a compact format suitable for mounting on microphone stands with the
optional DP48MB mounting bracket system (sold separately). All user controls
are laid out for ease of use on the top panel, while all primary connectors
are on the DP48’s rear panel. The DP48 Dual Monitoring Mixer uses a low-
latency, floating point audio engine to provide excellent stage and IEM (In
Ear Monitoring) sound with independent mixes for one or two users. The mixer
can be operated in two different modes: SINGLE (one mix for one musician, with
dual MY GROUP knobs available) and DUAL (separate mixes for two musicians).
The DP48’s AES50 connection provides 48 individual input channels at 48
kHz/24-bit resolution that can freely be mixed to 12 stereo groups. All 12
stereo groups feature semi-parametric 3-band EQ, compression and reverb sends.
Mixes A and B each have their own EQ processing and an adjustable brickwall
limiter to prevent excessive levels on the phones outputs. DP48 also includes
an automatic configuration function to simplify Channel-to-Group assignments
when setting up mixes. Now, instead of manually setting up your Groups from
scratch, DP48 can automatically evaluate the AES50 datastream and assign to
Groups 1-12 all channels that share specific common features, such as channel
colours or channel names. This auto-configuration function thereby allows the
engineer to easily distribute his mix structure throughout the connected IEM
(In Ear Monitoring) world.

Top and Rear Panels
- VOLUME knob controls the overall output volume for the knob’s respective mix.
- MY GROUP knob can be assigned to one of the 12 Groups to permanently control that Group’s level on the respective MIX A/MIX B output
- MIX A/MIX B buttons allow you to select the mix’s processing, including EQ, Limiter and Reverb return.(1) VOLUME knob controls the overall output volume for the knob’s respective mix.
- SETUP button accesses the settings mixer modes, SD recorder, reverb type, AUX IN input, ambience mic, brightness, remote control and other general preferences.
- SD-REC button opens the 2-track recording/playback operations when a FAT32 formatted SD card is present in the rear panel slot (see 24).
- PRESETS (SETUP and SD-REC pressed concurrently) allows you to store and load complete mix presets. You can import/export mix presets on SD cards, or use one of the 12 internal memory slots. Use the RESET function to clear the 12 memory slots and re-establish the preferred factory status.
- DISPLAY shows data about the current mix, including parameters, channel levels and channel groups.
- SELECT/EDIT push encoder allows you to select and adjust various parameters.
- EDIT button allows access to the Level and Pan adjustments for input signals assigned to the selected Group. The default setting for Level and Pan is center. The selected Group will be soloed automatically while making adjustments in Edit Mode. ASSIGN button is used to assign channels to groups.
- The selected AES50 input channel will be soloed automatically to make channel assignments easier.
- When either a MIX A/MIX B button OR any Group button is active, then the processing (i.e., EQ, Compressor and Reverb) for that Group or mix can be adjusted.
- LOW ( ) button selects the bass equilisation parameter for the currently-selected group, or for the selected Mix A or B. Make adjustments by rotating the SELECT/EDIT push encoder. The LOW ( ) button also acts as a control for SD recording/playback.
- (12) MID ( ) button selects the mid-range equilisation parameter for the currently-selected group, or for the selected Mix A or B. Make adjustments by rotating the SELECT/EDIT push encoder. The MID( ) button also acts as a control for SD recording/playback.
- MID ( ) button selects the mid-range equilisation parameter for the currently-selected group, or for the selected Mix A or B. Make adjustments by rotating the SELECT/EDIT push encoder. The MID( ) button also acts as a control for SD recording/playback.
- HIGH ( ) button selects the treble equilisation parameter for the currently-selected group, or for the selected Mix A or B. Make adjustments by rotating the SELECT/EDIT push encoder. The HIGH( ) button also acts as a control for SD recording/playback.
- COMP( ) button opens the Group COMPRESSOR or LIMITER windows, depending on the selected GROUPS 1-12 or MIX A/MIX B button:
- When GROUPS 1-12 buttons are selected, you can adjust that Group’s compression settings
- When MIX A or MIX B buttons are selected, you can adjust the peak limiting threshold for the selected mix. (NOTE: The limiter is always on.) The COMP( ) button also acts as a control for SD recording/playback.

- (23) AES50 THRU/IN EtherCON sockets provide connection to digital consoles. The AES50 connection can pass audio and control data in both directions via shielded Cat-5e Ethernet cables. The AES50 IN socket also accepts remote PoE (Power over Ethernet) for adapter-free operation for the first DP48 connected over AES50. Each socket has a pair of red and green LEDs, which indicate the following:
- Green pulsating and red extinguished = valid audio and valid control data; active link.
- Green constantly illuminated and red extinguished = valid audio and valid control data; standby link.
- Green extinguished and red illuminated = no clock sync available, no audio; link has failed.
- (24) DATA/REC slot allows you to record a personal stereo mix directly to SD card media. Mixes recorded to a SD card can be played back to Mix A or Mix B directly (the playback Level is set in pg. 3/8 of the Setup menu).
- AUX IN inputs allow additional mono (L input only) inputs to be routed into the mix using cables with ¼” TRS connectors (e.g., for inserting a local click track or
- PHONES A/B outputs sends the active mix out for monitoring over headphones or other monitoring systems.
- MONO output jacks can be used to send out a line-level, balanced mono signal over cables with ¼” TRS connectors (e.g., for feeding a local stage monitor).
