MixPre-D User Guide and Technical Information

Inputs

The MixPre-D features two transformer balanced analog inputs. Each input provides enough gain to amplify a variety of signals from low-sensitivity ribbon and dynamic microphones, medium-level wireless and condenser microphones, and “hot” line level signals.

The XLR inputs of the MixPre-D are transformer-balanced. The isolation characteristics of transformers are superior to other balancing techniques and are ideal for the hostile and uncontrolled environments of field production. Transformers provide galvanic isolation from the driving source, meaning there is no direct electrical connection. Signals are “transformed” magnetically. The input transformers in the MixPre-D use premium magnetic core material to achieve high signal handling capability

(especially at low frequencies) while keeping distortion to a minimum. Because of their inherently high common mode impedance, transformers are unrivaled by any other type of input for commonmode noise rejection.

The inputs of the MixPre-D can be used as balanced or unbalanced. When unbalancing, ground pin-3 to pin-1 of the XLR connector. There is no change in gain between unbalanced and balanced connections into the MixPre-D.

Mic / Line Setting

Before plugging a source into an XLR input on the MixPre-D, set the Mic/Line and phantom powering switch to the correct position:

48V

MIC

Setting

LINE

Input Source

Condenser microphones requiring phantom power

Dynamic microphones, some ribbon microphones, devices outputting mic-level signal (for example, wireless receivers) .

Devices outputting line-level signal (outputs from other mixers, for example)

Phantom Power

Phantom powering is a fixed DC voltage at either 12 or 48 volts. This voltage is resistively applied to pin-2 and pin-3 of an XLR connector relative to pin-1. There is no voltage difference between the signal pins-2 and -3. Dynamic microphones will operate as normal when phantom power is applied to them.

The MixPre-D can provide up to 10 mA to each input at 48 V, sufficient for the most power-hungry condenser microphones. Many phantom powered microphones do not require 48 V and can be properly powered with 12 V. When acceptable, use 12 V phantom to extend the MixPre-D’s battery life.

The phantom voltage level can be set to either 12 V or 48 V and is applied across all inputs where phantom power is selected.

To change the phantom voltage between 12 V and 48 V, hold down the Headphone Controller and slide the Slate switch into the slate position. The 12 V Phantom LED on the left side panel illuminates green when the phantom voltage is set to 12 V.

Input Gain Control

The amount of gain applied to an input is adjusted with the Input Gain Control. A fully clockwise position results in no signal passing from the input to the output bus (muted).

Up to 66 dB of gain is available from for microphone inputs.

MixPre-D User Guide and Technical Information

High-pass Filter

Each input of the MixPre-D has a two-position high-pass filter. High-pass (or low-cut/low frequency roll-off) filters are useful for removing excess low frequency energy in audio signals. Wind noise is a common unwanted low frequency signal and a high-pass filter is effective for reducing wind noise.

For most audio applications engaging the high-pass filter is beneficial, since little usable audio information exists below 80 Hz, especially for speech reproduction.

The MixPre-D’s high-pass filters feature a 6 dB/octave slope with either 80 Hz or 160 Hz corner (-3 dB) frequencies. The 160 Hz setting is used when aggressive filtering is required. The MixPre-D’s high-pass circuit is unique because of its placement before any electronic amplification. Most mixer’s high-pass circuits are placed after the mic preamp, where all of the high-energy low-frequency signals get amplified. Because the MixPre-D’s circuit cuts low-frequency signals before amplifying, higher headroom is achieved in presence of signals with a high amount of low-frequency energy.

When possible, attempt to equalize at the sound source with microphone selection, use of windscreens, microphone placement, and on-board microphone filtering. Many microphones have onboard high pass filters, and the high-pass filters on the MixPre-D can be used in conjunction with the microphone’s filters to increase the filter’s slope.

The three available high-pass filter settings are switched for each input by pressing the Input Button for the adjacent input. The two blue High-pass Filter LEDs for each input indicate the setting of the high-pass filter for the adjacent input.

Limiters

The MixPre-D Limiters act solely as “safety” limiters. Activate the Limiters using the front panel

“LIM” switch. Both input and output limiters are active, with input limiters preventing overload of the input stage and output limiters preventing the MixPre-D from overloading the next device in the signal chain.

In normal operation, with a properly set gain structure, the limiter threshold is only occasionally reached. In the presence of extremely high input signal levels, such as in high SPL environments, the limiter(s) activate to prevent the input signal from clipping. The limiters have no effect on audio below the set threshold.

When Inputs 1 and 2 are linked as a stereo pair, the limiters also link; gain reduction is equal for both inputs.

To change the threshold of the limiters, hold down both the Input 1 Button and the Input 2 Button and turn the Headphone Controller.

Pan Switch

The pan switches assign inputs to the channels of the output bus. Inputs can be sent to the left, right, or both outputs equally. The MixPre-D features excellent “off-attenuation” in the left and right positions. With the use of the pan switches, separate mixes can be sent to the left and right outputs. For example, a summed mono mix of both inputs can be sent to the right output while a single input can be sent to the left output.

Inputs 3 and 4

Each channel of the Tape Return input can be routed to various locations. When additional inputs are needed (such as when multiple wireless receivers are used) the Tape Return channels can be independently routed to the main output bus of the MixPre-D to act as additional inputs (3 and 4).

5

MixPre-D User Guide and Technical Information

To cycle between the available routings of the Tape Return signal, hold down the Input 1 Button (for

Channel 3) or the Input 2 Button (for Channel 4) and press the Headphone Controller. An LED in the right meter will illuminate to represent the destination of the routing:

-30: RTN L (Channel 3) or RTN R (Channel 4)

-18: Left output bus.

-16: Center (left and right) output bus

-14: Right output bus

When any channel of the Tape Return input is routed to the main output bus, the RTN Monitor

Source is disabled.

The TAPE RTN (Input 3 and 4) Input is an unbalanced stereo input that is suitable for tape or line level devices only. There are no microphone preamps on Inputs 3 and 4.

Input Linking

Stereo linking allows Inputs 1 and 2 to be controlled as a single, stereo input. This is useful when stereo microphones or stereo line level signals are used with the MixPre-D. There are two modes of operation for stereo linking, X/Y link and MS stereo.

The Linked status of the inputs is indicated by the Link LEDs on the front panel. When both LEDs are off, the inputs are not linked. To cycle between linking configurations hold down both Input 1 and Input 2 Buttons and slide the Slate Switch to the Slate position.

X/Y Stereo Link

When in X/Y stereo link operation, Input 2’s Pan Switch controls the stereo image (L: Input 1 = Left,

Input 2 = Right; C: Both Inputs in both channels; R: Input 1 = Right, Input 2 = Left). Channel 2’s

Fader controls the overall level of the stereo pair. Input 1 and 2’s High-pass Filters continue to act independently of each other. When linked, Input 1 and 2’s Limiters are also linked.

MS Stereo Linking

When MS stereo linking is selected in the Setup Menu, Inputs 1 and 2 are linked as an MS (Mid-Side) stereo pair. Connect the mid signal (unidirectional / cardioid microphone) to Input 1 and the side signal (bi-directional microphone) to input 2.

Input 2’s Level Control adjusts the overall gain of the MS stereo pair. Input 1’s Level Control adjusts the “spread”, or width of the stereo image. Input 2’s Pan Switch controls the polarity of the side signal (L: Normal, R: Inverted). Reverse polarity to flip the stereo image between right and left. The center (“C”) position of Input 2’s Pan Switch mutes the side signal; only the mid signal is present, resulting in a mono signal. Input 1’s Pan Switch is disabled in MS linking mode. Input 1 and 2’s

High-pass Filters continue to act independently of each other.

Outputs

The MixPre-D is a two-output-bus mixer. Each input can be “hard panned” between the left and right output bus making it easy to use the MixPre-D in either stereo or dual-mono operations. Because dialog is often recorded in mono, each output connector can be used to send signal to separate cameras or recorders. The MixPre-D’s XLR Outputs, Tape Outputs, Stereo Unbalanced Mic Outputs, and AES Digital Output share the same program content and pan assignment.

There is no master level control on the MixPre-D. The master is factory-set to unity gain, or “0” dB.

MixPre-D User Guide and Technical Information

XLR Outputs

The two XLR outputs are active-balanced connections, each capable of driving long lines. These connections can be used as either balanced or unbalanced. When unbalancing, use pin-2 for (+) and pin-1 for ground; float (leave open) pin-3.

Tape Output

The Tape Output is typically used to interface with consumer inputs such as Comtek inputs or consumer transcription recorders. The MixPre-D has an unbalanced, two-channel tape level output on a single, TRS 3.5 mm connector.

The Tape Output program is identical to the XLR Output. Tape Out level is fixed at a -10 dBu nominal level and is electrically isolated from the XLR Outputs. Additionally, the Tape Output is used for the Mix Out signal to link multiple Sound Devices mixers.

See Mixer Linking

.

AES Digital Output

The Right XLR Output can be set to AES digital signal by sliding the XLR Output switch to “AES”. In this configuration, the Right XLR Output contains both channels of the MixPre-D’s output as a balanced, AES3 signal. All other outputs are unaffected, so inputs panned left will appear on the left channel of the AES output plus the left channel of all analog outputs (including the left XLR main output).

Sampling Rate

The MixPre-D’s digital system operates at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. When either a USB connection or AES output is enabled the operating sample rate of the MixPre-D is indicated by the front panel Sample Rate LEDs. If AES output is disabled and there is no USB connection to a computer both Sample Rate LEDs are off.

To change the sampling rate of the MixPre-D, hold down the Headphone Controller while sliding the Right XLR Output switch to “AES”.

When connected to a computer with a USB cable, the sample rate of the MixPre-D is set by the computer’s operating system and the sample rate cannot be changed from the MixPre-D. See Computer Interface

Stereo Unbalanced Mic Output

The Stereo Unbalanced Mic Output is designed to interface with “pro-sumer” DSLRtype cameras. The MixPre-D has an unbalanced, two-channel “hot” mic level output on a single, locking, TA3M connector.

The Stereo Unbalanced Mic Output program is identical to the XLR Output. This output is fixed at a -36 dBu.

Monitoring

Headphone Gain

Headphone output level is controlled by the front panel Headphone Controller. While turning the Headphone Controller, the headphone gain level is indicated on the Right Output

Meter.

Metering

The MixPre-D features two large 16-segment LED output meters.

The meters use energy-efficient GaN LEDs, which are clearly visible in full sunlight. The MixPre-D output meters are unaffected by shock, temperature, or humidity extremes.

The MixPre-D meters display input levels in a peak + VU format. The perceived loudness (VU) is displayed on a bar graph, and the Peak signal on a dot above the VU. This metering format provides the best of both VU and Peak metering by seeing the “loudness” of the signal while simultaneously showing peaks.

To adjust the brightness of the meters (and other front panel LEDs) slide and hold the Slate Switch in the Slate position and turn the Headphone Controller.

Tone Oscillator & Slate Microphone

A single, two-position switch controls both the slate microphone and the tone oscillator.

Slate Microphone

The built-in MixPre-D slate microphone is used to notate scenes from the mixer location. Its audio performance is not suitable for critical recording applications; it should be used for documenting scenes and for communication purposes only.

The slate mic uses the momentary right switch position. Hold the switch to the right to activate, and release to turn off. Program audio is muted when the slate mic is active. The slate is sent to all outputs.

Tone Oscillator

Tone is used to set gain between the MixPre-D and the next device in the signal path. The tone oscillator uses the locking left position of the slide switch. Slide left to activate, and slide right to deactivate.

The tone oscillator outputs a 1 kHz sine wave at 0 dBu to the outputs (when the outputs are set to

Line Level). Program audio is muted when tone is active. Tone is sent to all outputs. The MixPre-D headphone outputs are attenuated when tone is activated.

MixPre-D User Guide and Technical Information

Powering

The MixPre-D can be powered from either internal batteries or from external DC. The power-efficient

MixPre-D can operate from two AA alkaline batteries for nearly a production day (less with phantom powering). While many users prefer external DC sources to power both their mixer and wireless receivers, the use of internal batteries is perfectly feasible for both primary and backup powering of the MixPre-D.

Power Switch and LED

The 3-position power switch selects between internal batteries, external DC, or power off. There is sufficient capacitance in the power supply circuit to toggle between internal and external without any disruption in audio.

The power LED illuminates solid green to indicate good power. The power LED flashes green when the internal batteries are low.

Internal Batteries

The MixPre-D accepts two standard AA batteries (1.2 to 1.65 Volts). The robust battery cap and tube are sealed to prevent inadvertent battery leakage from reaching internal circuitry. The threaded-nickel cap extends beyond the panel to make battery changes easy and quick.

Remove batteries when the unit is stored for extended periods.

External DC Sources

For extended mixer runtime use an external DC source. The MixPre-D can be powered from any DC source with a voltage range of 10 volts to 18 volts. If an over voltage is applied to the mixer, an internal poly fuse is opened to prevent mixer damage. The fuse is reset when the voltage is removed.

The external DC supply is isolated (floating) from the circuitry to minimize ground loop and interaction among devices sharing the same DC source. The external DC connector is a Hirose 4-pin female.

This locking connector mates to Hirose P/N HR10-7P-4P (Sound Devices P/N XL-H). Pin-1 is negative and pin-4 is the positive voltage.

Computer Interface

The MixPre-D is an USB Audio Device Class peripheral. When attached to a computer as an audio interface, the stereo output bus is sent to the computer as left and right inputs and the left/right audio output of the computer is sent to the headphone output of the MixPre-D.

No proprietary drivers are required to operate the MixPre-D. The MixPre-D directly operates with

Mac OS 10.4+, Windows XP, Vista, and 7 (both 32- and 64-bit), or Linux (

See Computer System Requirements

for details). The first time the MixPre-D is plugged in, the operating system will enable standard USB Audio Device Class drivers automatically (if necessary).

When connecting the MixPre-D to computers running Linux or any version of Macintosh OS X previous to 10.5.8, it is necessary to run the MixPre-D in “full-speed” USB mode. To do this, hold down the

Headphone Controller while inserting the USB plug to the MixPre-D.
