AtlasSound.com TSD-PA20VG 1x20W Global Commercial Amplifier Owner’s Manual Description The Atlas Sound TSD-PA20VG is a cost-effective mono amplifier for 4Ω and distributed constant voltage (25/70/100V) speaker systems. Applications such as house of worship cry rooms, hallways, restrooms, foyers, and classrooms will benefit from this compact reliable amplifier. The TSD-PA20V is also a cost-effective alternative for small projector systems as it can be used with as many as (16) 25/70/100V ceiling speakers (tapped at 1W each), plus the extremely small footprint allows for easy mounting. For sound masking applications the TSD-PA20VG has the capacity to drive up to 34 masking speakers tapped at .5W each on a 70.7V line. Output is gain controlled from a potentiometer on the front panel with removable knob to facilitate installation of a tamper-resistant cover (included). The TSD-PA20VG is part of a full line of Atlas Sound Time Saving Devices. These compact (1.5" x 4" x 5.2") units are designed to solve some of the common audio system problems in the easiest, 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-resistant security covers. The TSDs are highly efficient and meet most energy standards as one 24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.

Owner’s Manual TSD-PA20VG 1x20W Global Commercial Amplifier Front Panel Description 5 4 3 2 5 5 1 1. Input Level Control - Determines the output level at the loudspeakers on the PA20VG. Turn clockwise to increase the signal level and counter-clockwise to decrease the level. Note: The Input Level Control knob can be removed and replaced with a supplied security cover to prevent unauthorized adjustment. 2. Power LED - Illuminates Blue when 24VDC power is present. 3. Signal LED - Illuminates Green when the input signal strength reaches 25mV to verify a signal path. 4. Peak LED - Illuminates Red when the input 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. 5. 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-PA20VG 1x20W Global Commercial Amplifier Owner’s Manual Rear Panel Description 4 4 4 4 1 2 3 TSD Input/Output connections are removable for easy system wiring. The connectors have 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 TSDs 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. Please observe the polarity of the wiring to this connector. 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 Line Input - Connect balanced line level signals to this phoenix style connectors. Your connection must be mated properly to the input connector or signal loss and/or noise may occur. Note: Unbalanced line level inputs can also be used by connecting the (G) and (-) terminals together. 3. Speaker Outputs - Connect the loudspeaker wiring to these terminals, observing the polarity shown on the rear of the chassis. For low impedance loads, use the “COM” and 4Ω terminals. For high impedance loads, use “COM” and the proper terminal for your system (25/70/100V). It is recommended to keep the sum total of tapped loudspeakers to 20W. 4. Cable Management Retainer Points - Use the rear panel screws for connecting the included cable retainers. Each TSD comes with two cable retainers for simplified cable management. 1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.

Owner’s Manual TSD-PA20VG 1x20W Global Commercial Amplifier Knob and Security Cover All front panel level controls feature a removable knob that can be replaced with included security covers to prevent potentiometer damage or unwanted changes. • 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. • 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. Mounting There are three ways to securely mount this TSD: 1.Velcro™ - Each unit includes industrial-grade Velcro™ with adhesive backing to adhere to any flat surface. 2. Brackets - Each unit includes two mounting brackets to secure to a cabinet or wall. 3. Rack Mount Panel - The optional TSD-RMK rack mount panel supports up to four TSDs in a 1RU space. 1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.
