Chapter 1 Introduction Section To avoid personal injury, do not remove the top cover from the power Do not remove covers or panels supply, or the rear panel of the Xtramix and never operate the external power supply without the cover properly installed. If it becomes necessary to remove the rear panel of the Xtramix for service, always unplug the AC power and disconnect the DC interface cable before proceeding. -
Page 9: Master Section
Chapter 1 Introduction Section Master section The master section provides the Xtramix with many choices for routing and controlling the line signals from the input section and effects devices from the effects section. The master section includes 8 discrete subgroup level controls, a stereo program, stereo monitor, and stereo headphone controls. -

Page 14: Mechanical Installation
Chapter 3 Installation Section Installation The following information should give you the basics on how to install General the Xtramix and Power Supply. The proper installation of the Xtramix as a part of a larger system requires a clear understanding of audio wiring, AC distribution, grounding, and shielding techniques. -
Page 15: Configuring The Ac
Chapter 3 Installation Section One of the primary reasons that the power supply of the Xtramix is external is to insure that the power transformer enclosed within the power supply chassis maintains a safe distance from the active electronics of the Xtramix. For that matter, any power supply (especially the small wall mount supplies), power amplifiers, or any strong power field device should be kept at a reasonable distance from the Xtramix. -

Page 20: Chapter 4 Operation
It is assumed that you have a working knowledge of audio and signal flow. If this is your first mixer it is suggested that you purchase a book on the basic operation of audio mixers. Speck Electronics will be happy to suggest some publications on this subject. - Page 21 Chapter 4 Operation Section Figure 2. Input Channel...
- Page 22 Chapter 4 Operation Section Refer to Figure 2 for location of items 1 thru 15. The smaller (inner) knob of the gray capped concentric is a dual rotary 1. Input Level Control potentiometer that simultaneously and equally adjusts both the left and right channel levels.
-
Page 23: Channel Subgroup Assign/Mute Section
Chapter 4 Operation Section There are two types of In-Place solo incorporated into the Xtramix: Absolute and True. All input channel solos are Absolute In-place. This means that a soloed signal will be perceived in the same stereo or mono perspective being produced by the instrument itself. -
Page 24: Effects Send Section
Chapter 4 Operation Section 6. 3-4/7-8 Subgroup Assign/ When the Subgroup Assign Changeover Switch (see below) is in the up Mute Switch position, pressing the 3-4/7-8 Assign Switch routes the input channel signal to the 3-4 subgroup pair. When the Subgroup Assign Changeover Switch is in the down position, pressing the 3-4/7-8 Assign button routes the input channel signal to the 7-8 subgroup pair. -
Page 25: Odd Effects Sends
Chapter 4 Operation Section Odd Effects Sends 10. Odd Level Control The smaller (inner) knob of the black capped concentric adjusts the level being sent to the selected "Odd" effects bus. This control is used in conjunction with the Odd Effects Assign Switch and Odd Assign Changeover Switch. - Page 26 Chapter 4 Operation Section Figure 3. Stereo Effects Return Channel...
-
Page 27: Stereo Effects Return Section
Chapter 4 Operation Section Stereo Effects There are eight stereo effects returns incorporated into the Xtramix. Each of the effects returns are individually assignable, in stereo or Return Section mono, to the eight subgroups. Each return channel also incorporates a stereo return level control, pan/balance control, stereo/mono select switch and in-place solo switch. - Page 28 Chapter 4 Operation Section 19. Stereo Effects Return Depressing this switch sums the left and right effects inputs creating a Mono Switch mono composite. This feature will prove useful if a stereo effect is to be assigned to a single subgroup or specifically placed somewhere in the left to right perspective of a stereo subgroup.

-
Page 30: Monitor Section
Chapter 4 Operation Section Monitor Section This is the theoretical heart of the Xtramix. Here is where a stereo mix of all the subgroups is created, independent of the Bus/Subgroup Masters. The adjustment of the monitor section's Level and Pan controls create the stereo mix for the Program outputs, Monitor outputs and Headphone outputs. - Page 31 Chapter 4 Operation Section 27. Monitor Pan/Balance Control When the Bus/Line Switch on the monitor channel is selected to the Bus (subgroup) position, this control acts as a traditional left/right pan for the stereo Program, Monitor, and Headphone outputs. When the Bus/Line Switch is selected to the Line position, the Pan/Balance Control acts as a left/right balance control for an incoming stereo line signal.

Chapter 4 Operation Section Master Section Refer to Figure 5 for location of items 31 thru 48. 31. Bus/Subgroup Masters 1-8 These are the individual master level controls for the eight subgroup outputs. Metering for the bus/subgroup outputs is provided by two LED VU meters in selectable pairs (1/2, 3/4, 5/6, 7/8 ). - Page 34 Chapter 4 Operation Section 36. Stereo Program Master This pot acts as the master volume to the stereo program feed. It should be pointed out that the Left/Right program meters follow this master control, hence any adjustment to the Program Master Control is displayed at the program meters.

Page 40: Effects Send Connections And Switches
Chapter 4 Operation Section 4. Low/ High Select Switch Low/High refers to the output operating level of the signal source. It should be pointed out that the term Low/High has different meanings from one manufacturer to another. For the Xtramix, the term low and high refers to a medium strength line signal (-20dbu to 0dbu), and a high strength signal (0dbu to+28dbu) respectively. -
Page 41: Effects Return Connections
Chapter 4 Operation Section Simply connect an Effects or Auxiliary send from the external mixer to the Sum In Jack of any of the eight Xtramix send channels. While it makes sense, for the sake of continuity, to keep the Effects Send numbers matched (#1 of the external mixer to the Sum In point of #1 on the Xtramix, etc.) it is certainly not necessary. -
Page 42: Monitor Section Connections And Switches
Chapter 4 Operation Section 11. Assign Subgroup Each Bus/Subgroup channel provides a 1/4" T.R.S. (tip, ring, sleeve) Insert Jack insert jack. The Insert Jack provides line level interstage access to the assign subgroup bus before (pre) the Subgroup Master Level Control. This means that any device interfaced to this jack will be processed before its respective Subgroup Master Control, and will not be affected by any adjustments of the Subgroup Master Control. - Page 43 Chapter 4 Operation Section Figure 10.

Page 44: Tuner Section Connection And Control
Chapter 4 Operation Section Tuner Section Connection and Refer to Figure 10 for location of items 14 thru 24. 14. Tuner Feed Jack This 1/4" TRS phone type connector provides a dedicated feed to an external tuning device. The source for the output is either the sum of all signals feeding the program master or any signal(s) that is soloed. - Page 45 Chapter 4 Operation Section Each of the left and right program insert jacks employ a T.R.S. (tip, ring, sleeve) type jack. The ring of the 1/4" jack is the unbalanced insert send (pre the Program Master Level Control), the tip is the unbalanced insert return, and the sleeve is the signal ground.
- Page 46 Chapter 4 Operation Section Connections to the balanced program feed jacks should be made with a 1/4" stereo tip, ring and sleeve (TRS) plug as shown below in figure 12 . Fig 12. Stereo (TRS) plug When connecting the balanced program outputs to an unbalanced input, it will be necessary to configure your cables in order to unbalance the signal.
- Page 47 Chapter 4 Operation Section When set to the "pre" (factory default) position, level adjustments to the program level will not affect the monitor or headphone levels. This switch is recessed behind the rear panel to prevent inadvertent actuation while plugging or unplugging connectors. The switch may be depressed by inserting a thin pointed object into the hole (such as a very small screwdriver).
- Page 48 Chapter 4 Operation Section If required, the VU meters may be calibrated to indicate -10dbV. An AC voltmeter and signal generator will be required to perform this adjustment. 23. Power Supply Connector This 4 pin connector will accommodate the connector from the power supply cable.
