  • Page 4: Introduction

    Psychologist Mixer User Manual Introduction This manual describes the components and operations of the Psychologist, a monitor mixing system based on the standard Intelix Matrix Mixer and Mini-Mixer remote controls. Together we’ll call them the Psychologist System, or just the system.

  • Page 5: Safety Instruction

    Psychologist Mixer User Manual Safety Instruction Note: Read all the directions carefully before use. Take all the precautions usually taken with electrical equipment. To protect both the users and the equipment: Grounding Make sure both the Matrix and the devices connected to it are properly grounded.

  • Page 6: Quick Start

    Psychologist Mixer User Manual Quick Start This section describes how to get your Psychologist system up and running. This section covers most typical installations. If your system has any unusual features, or you need to know more about how your system works, read the chapter associated with each step. For more detailed installation instruc- tions, see System Installation Reference, on page 20.
  • Page 7 Psychologist Mixer User Manual Connect the inputs to the blocks on the left of the Matrix unit. Connect the outputs to the blocks on the right hand side of the Matrix unit. (This illustration shows an 8 x 8 Matrix Mixer. Your system may be different.)

  • Page 9 Psychologist Mixer User Manual 8. Connect the Mini-Mixers one at a time. Connect the Mini-Mixer with lengths of PC cables. The DB9F connectors can connect to either of the two interchangeable ports on the side of the Mini-Mixers. Verify that the Mini-Mixer is powered up and communicating with the Matrix Mixer as indi- cated by a steady-on status LED before connecting the next Mini-Mixer.

  • Page 10: System Description

    Audio Matrix Mixer The Psychologist is based on the Intelix Matrix Mixer, which allows audio signals from mul- tiple sources to be sent to multiple destinations. The Matrix Mixer is designed so that audio inputs can be independently mixed to any and all outputs simultaneously.
  • Page 11 Psychologist Mixer User Manual LED/DIP Switch position: The “power” (red) LED lights when the Matrix is powered on. The “Status” (green) LED lights when the reset button is being pressed. The DIP switches are used to delete remote controls which are not responding. See Troubleshooting Tips on page 27 for more informa tion.

  • Page 12: Signal-To-Noise

    100 dB. Using the power amp to raise signal levels, rather than a pre-Matrix amplifier or the Matrix itself, diminishes this high level of performance. For best performance, feed the Psychologist with direct outputs or subgroups from the main mixing console and raise levels to about +4dB.
  • Page 13 Psychologist Mixer User Manual Fig. 13. Correct Signal Balancing. This drawing shows the result of correctly following the system balancing procedure detailed above. The input signal is in the range of +4dB to +26 dB. With the Matrix attenuation controls set to -12dB the input signal is attenuated to -8dB. The resulting signal- to-noise ratio is improved to more than 80dB.

  • Page 14: Inputs And Outputs

    If the switch is in the up position, escape and checksum are used. If the switch is down escape byte and checksum are not used. Intelix recommends using escape byte and checksum in applications where RS232 communication may be hindered due to cable length (a maximum of 50 feet) or lack of shielding from external electronic noise.

    The status LED near the master volume control indicates that the unit is on. (See Status LED on page 17 for more information.) A typical Psychologist Mini-Mixer is shown below. Psychologist Mixer User Manual...

  • Page 16: 8/1 Mini-Mixer

    Psychologist Mixer User Manual You can use several different styles of Mini-Mixers with the Psychologist system. Mini-Mixers have either rotary or slider potentiometer controls (“pots”), with 8, 16 or 32 input channels in mon- aural or stereo output. The different styles of Mini-Mixers, and the configurations that can result from their combined use, are described below.

  • Page 17: Mini-Mixer Configuration

    Psychologist Mixer User Manual Mini-Mixer Configuration Status LED An LED near the master knob (see page 15) indicates the status of the Mini-Mixer. The output of the LED indicates the status of the Mini-Mixer. Steady On The Mini-Mixer is powered up and communicating with the Matrix. This is the normal condition.

    Psychologist Mixer User Manual Mini-Mixer location selector Each Psychologist system ships with Mini-Mixers configured to control an output on the Matrix. Follow the instructions below to add additional Mini-Mixers or alter the system configuration. The two rotary decimal switches (see page 26) within the Mini-Mixer determine which physical output location (and I/O channel) the Matrix Mixer associates with that Mini-Mixer.

  • Page 19: Reo Bus Connections

    AC or DC. If DC, positive voltage should be connected to pin 9, and ground connected to pin 6. The voltage should be 9 to 12 volts. Note: The color code shown below is specific for Gepco 6608, the cable recommended by Intelix. ReO Bus Connections The ReO bus that connects the minimixer remotes to the matrix mixer has the following pinout.

  • Page 20: System Installation Reference

    AC Power Connection Intelix supplies an 18 Volt, 3.0 (or 1.5) Amp center-tapped transformer to power the Mixer. If you use another AC supply, it must supply 18 volts and have at least a 21 VA rating for an 8 x 8 matrix and 60 Volt-Amp rating for larger matrices.

    Matrix. Grounding the Minimixer In high static environments, it may be necessary to add local grounds to Psychologist minimixers. This is most easily done at installation time, so if you suspect that you will have high static condi- tions such as thick carpet or other static causing conditions, you should locally ground your minimixers at the time of installation.

  • Page 22: Audio Input Impedance

    Psychologist Mixer User Manual Audio Input Impedance Any line-level audio input can be mixed and routed using the Matrix. The audio input to the Matrix is can be either electronically balanced (impedance of 20KΩ), or it can be unbalanced (impedance of 10KΩ) by the user.
