Raven MTX2 Analog Section Manual
The Raven MTX2 Analog Section consists of a rackmount unit, the “2RU,” and left and right-hand control modules.
Their functions and features are described in this guide.
Overview
The RAVEN MTX2 is a full featured monitor controller that facilitates high fidelity, intuitive and flexible listening on
studio speakers, headphones, and cue systems. Multiple inputs can be routed to multiple output destinations. The
standard RAVEN MTX2 configuration operates in stereo (and mono), whereas an optional surround module enables
the RAVEN MTX2 to operate in 5.1 or 7.1 surround.
Please
browse this entire guide before contacting the support team as it will answer most of your questions and we
took great care in writing it.

The Usual Warnings
★Remember to switch off or mute any and all power amps, including those on powered monitors and in
headphone amps before turning the Analog Section on or off. Damage may occur if you do not!
★Please do not electrocute yourself while installing the unit. Mains voltage can be very, very dangerous and is
not a thing to trifle with.
★Please do not connect or disconnect the ethernet cables between the 2RU and the modules while the power
to the 2RU is switched on. Those cables carry voltage and can harm both the modules and the 2RU if
hot-patched.
★Confirm the pinouts of any and all cabling before connecting it to the system.
★Monitoring at loud volumes can be very damaging to your ears and the ears of others, even for short
durations. The CDC and many other institutions have researched what constitutes a safe listening
environment and it is advisable to familiarize yourself with their findings before working long, late hours
listening too loud.
★From time to time voltages higher than those of normal audio signals are present on audio cabling, such as
phantom power. Be very careful not to apply this voltage to the analog section, as it may hurt the tiny
hamsters that power the unit.

2RU
The 2RU is where the bulk of the connections are made. The AC Power inlet accepts a standard IEC cable and
houses two fuses for protection. Please ensure you have the correct mains voltage for your unit before
powering on. There are two cards in a stereo unit, the Aux Card and the Stereo Card. Surround Units include
a Surround Card. Most connections are made with 25 pin Dsubs that follow the standard pinout. In case you
need that pinout, here it is:

★When LIGHTS button is ON, all inactive buttons will illuminate RED.
★When LIGHTS button is OFF, all inactive buttons are not illuminated.
Meter:
Switches between the sources monitored on the VU Meter Bridge. Please note the meter bridge is
discontinued, but these options are still switched on the “Meter Out” DB25 if you wish to make use of
these outputs.
★Normal mode monitors Source outputs. Meter modes illuminate blue when activated.
★Secondary Mode monitors CUE outputs. Meter modes illuminate red when activated.
★Surround mode monitors all speaker outputs. Meter modes illuminate white when
activated.
Talkback:

Speaker Management Panel
Selects which speakers of the currently selected set are active. Global for all speaker sets.
“Surround 2” injects the Surround 2 Inputs into the monitor path.
SPEAKER MUTE / SOLO and Surround Mode
Whether operating in stereo or surround mode, any connected SPEAKER can be individually muted
or soloed via the Speaker Mute buttons. A momentary press will mute the selected speaker, while a 2
second hold will solo that speaker. One can also mute or solo multiple speakers simultaneously by
pressing two buttons at once. You may wish to solo two surround channels at the same time or
perhaps solo the L, C, and R speakers together.
Raven MTX2 Analog Section Manual Page 6
In Stereo mode, only the L and R buttons are functional. In Surround mode, all speakers up to 7.1
can be muted individually. Normally the buttons will be blue, and they will turn purple when
surround mode is activated.
Cue 2 & Studio Section
Cue 2 and the SLS (Studio Loudspeakers) share some controls but not all.
CUE 2 & Studio rotary source selector:
Selects which audio source is being monitored on CUE 2 & Studio.

Raven MTX2 Analog Section Manual Page 7
Right Control Module
The right control module includes speaker set selector, control room volume and functions, source
selector and additional talkback functions. It also contains the global talkback volume, mono, dim
and mute.
Speaker Selector Panel
Stereo Speaker Outputs:
RAVEN MTX2 sends attenuated audio to multiple pairs of speakers. In stereo mode, RAVEN MTX2
can send to three external speakers (A, B, & C) (plus optional discontinued “Betty” Laptop
Reference™ speakers). You may also mute the output entirely or sum the speakers to mono with the
provided controls.
SPEAKER C Subwoofer Mode:
★SPEAKER C normally operates as a discrete stereo speaker output, just like SPEAKER A and
B. But SPEAKER C can also act as a subwoofer On/Off selector and be paired with SPEAKER
A, B or both.
★Activate SPEAKER C Subwoofer Mode by holding down SPEAKER A and then SPEAKER C.
Thereafter, SPEAKER C output toggles On and Off with each momentary press, while
SPEAKER A remains On. SPEAKER C Subwoofer Mode can also be paired with SPEAKER B by
the same method.
★To deactivate SPEAKER C subwoofer mode, press and hold Speakers A and C together. If
SPEAKER C has also been paired with B, un-pair them by the same above method.
★Please note that this arrangement is not managed with a crossover and may inflate your
bass response if not calibrated.
SOURCE Inputs
RAVEN MTX’s source inputs are designed to integrate seamlessly with an 8-output DAW interface
simply by connecting the interface’s first 8 outputs (often a standard DB25 to DB25 cable) to RAVEN
MTX’s Input1 DB25. No patching will be required to instantly go back and forth between tracking
and mixing, in Stereo or Surround (optional). The input selections are as follows:
★Mix 1
★Mix 2
★Cue A/B
★Cue C/D
★iDock
★Aux
★Digi
★Surr1
It is important to note that when a Surround Card is present, selecting “Surr1” routes the
eight channel main inputs to the surround set. That is, audio from Mix 1, Mix 2, and Cue
A/B/C/D become the surround 1 inputs in surround mode and when selected. You may still
use the discrete inputs for their regular purpose when not in surround mode. There is also
the option of a second set of inputs, “Surr2.” The selector for that input is on the
left-hand-module as indicated above.
Raven MTX2 Analog Section Manual Page 8
Monitoring Extras
★MONO sums the stereo signal to mono
★MUTE mutes the output
★DIM dims the output 20dB
Talkback:
Injects the talkback microphone signal into the CUE system.
★Press and hold – keeps the talkback ON as long as TALKBACK is pressed.
★Quick momentary press – Toggles TALKBACK ON. Toggles OFF with another single press.
★EXP Engages External Talkback Mic
★Control Room monitor is dimmed 20db while talkback is engaged
Additional Talk-Back Functions
It is on the right-hand module that we select where
talkback goes to when we depress either of the
talk buttons or engage the auto-talkback. You may talk to the Cues (Global for 1&2) or the SLS (Studio
Loudspeaker) outputs. You will find also the buttons to engage the auto-talkback and the “Exp”
button, which selects an external talkback input. There is also a level control for the talkback, global
to both inputs and a Control Room Dim button.
When Auto-Talkback is engaged, the talkback will remain engaged unless a signal of -37 or greater is
presented to cable pair 8 of the Aux I/O DB25 on the Aux Card (See Pinouts Above).
