AtlasSound.com TSD-MIX41 4x1 Mic/Line Mixer Owner’s Manual Description The Atlas Sound TSD-MIX41 4x1 mic/line mixer is ideal for applications where multiple mic or line sources need to be sub mixed or summed. In House of Worship applications the TSD-MIX41 is especially useful for combining similar sources such as choir microphones to a single mixer channel. The unit also works well as a stand-alone mic/line mixer that can be easily interfaced with Atlas Sound amplifiers. Other applications include restaurants, conference rooms, and schools. Each input is mic/line switchable with phantom power provided for condenser microphones. The high quality, low noise internal mic preamps ensure clarity and quiet operation without unwanted coloration. A 12dB/octave high pass filter @ 125Hz also is available on each input to minimize bass rumble and low frequency feedback. The TSD-MIX41 is part of a full line of Atlas Sound Time Saving Devices. These compact (1.5" x 4" x 2.75") units are designed to solve some of the common audio system problems in the easiest and in the most efficient and cost-effective way. All models are made from high quality components and include removable individual I/O connectors for quick and precise wiring, separate ground terminals for all I/Os assuring secured connections, and removable level controls that can be replaced with tamper-proof security covers. The TSDs are highly efficient and meet Energy Star™ standards as one 24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.

TSD-MIX41 4x1 Mic/Line Mixer Owner’s Manual Front Panel Description 6 6 5 4 3 6 6 1 2 1. Inputs 1-4 Level Controls - Adjusts the gain of the independent input signals. Turn clockwise to increase the signal level and counter-clockwise to decrease it. Note: The Input Level Control knobs can be removed and replaced with a supplied security cover to prevent unauthorized adjustment. 2. Mixed Output Level Conrol - Adjust the output level of the summed signals from the four inputs. Turn clockwise to increase the signal level and counter-clockwise to decrease it. Note: The output level control knobs can be removed and replaced with supplied security covers to prevent unauthorized adjustment. 3. Power LED - Illuminates BLUE when 24VDC power is present. 4. Output Signal LED - Illuminates Green when the input signal strength reaches 25mV to verify a signal path. Note: The LED will not illuminate if the output Level is turned Off. 5. Output Peak LED - Illuminates Red when the output signal reaches 3dBV below when signal clipping will occur. Occasional flashing is normal but if this indicator is continuously On, then reduce the input level using the input level control on the front panel. 6. Bracket Retainer Points - Each TSD includes two mounting brackets for securing the TSD to a cabinet or wall. Remove screws and align the bracket with the panel hole before firmly tightening the screws. 1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.

AtlasSound.com TSD-MIX41 4x1 Mic/Line Mixer Owner’s Manual Rear Panel Description 4 4 3 4 4 1 2 TSD Input/Output connections are removable for easy system wiring. The connector has a 3.5mm pitch between pins. 1. DC Power Input - Each TSD that requires DC power comes with a 2 position connector for an external 24VDC power supply (sold separately). Because of the TSD’s low power consumption, a single external power supply may power more than one TSD. Please refer to the specifications on current requirements in milliamps to match with the appropriate power supply. Note: It is acceptable to exceed the current requirements of the TSDs but NOT safe to use a power supply that is below the current requirement of the device. 2. Balanced Inputs 1-4 - Connects to balanced line or mic level sources. Your connection must be mated properly to the input connector or signal loss and/or noise may occur. For gain or source input type selection, refer to the “Dip Switch Function Identification” chart for proper input setting. Note: Unbalanced line level inputs can be inserted with proper wire configuration by connecting the (G) and (-) terminals together. 3. Balanced Line Output - Provides output when an input signal is present for connection to balanced line level devices. Your output connections must be connected properly to the connectors or loss and/or noise may be introduced into the signal. Note: Unbalanced line level devices can be used with proper wire configuration by connecting the (G) and (-) terminals together. 4. Cable Management Retainer Points - Each TSD includes two cable retainer straps for securing the included cable management retainers. Remove one of the rear panel screws, align the panel hole with a retainer and firmly tighten the screws. 1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.

Knob and Security Cover All front panel level controls feature a removable knob that can be replaced with an included security cover. Follow these steps to prevent potentiometer damage or unwanted changes. 1. Knob Installation - Turn the potentiometer shaft fully counter-clockwise. Align the knob indicator to the lowest setting on the panel and the potentiometer shaft slot. Carefully press the knob onto the potentiometer shaft. Do not force or damage may occur to the potentiometer. 2. Security Cover Installation – Remove the knob from the panel and insert the cover. Do not force or damage may occur to the potentiometer. Small pliers may be required to remove the knobs.
