SAFETY INSTRUCTIONS 1. 2. 3. 4. 5. Read Instructions -- All the safety and operation instructions should be read before this product is operated. Retain Instructions -- The safety and operating instructions should be kept for future reference. Heed Warnings -- All warnings on this product and in these operating instructions should be followed. Follow Instructions -- All operating and other instructions should be followed. Water and Moisture -- This product should not be used near water ­ for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc. Cleaning -- Clean only with a dry cloth. Ventilation -- This product should be situated so that its location or position does not interfere with its proper ventilation. For example, the Component should not be situated on a bed, sofa, rug, or similar surface that may block any ventilation openings, or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through ventilation openings. 6. 7. PORTABLE CART WARNING Carts and stands - The Component should be used only with a cart or stand that is recommended by the manufacturer. A Component and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the Component and cart combination to overturn. WARNING -- To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. 2 18. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in the following chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here.

Before you begin, please make sure you read the Safety Instructions on page 2 and Getting Started on page 4. Your new TAPCO® T·231 is designed to set up quickly and operate easily. We know it's often seen as a sign of weakness to read a manual, along with asking for directions when lost, but maybe you can read the rest when nobody is looking. It is important to keep your receipt in a safe place, and not a bad idea to write your product information here for future reference (i.e., insurance claims, tech support, return authorization, etc.).

All Rights Reserved. 3 Getting Started The following steps will help you set up your T·231, and get the levels just right. SETTINGS: 1. Be sure the T·231's POWER switch is off. 2. Set all the sliders to their center positions and all the switches out. SET THE CONTROLS: 1. Make sure your signal source is turned up and delivering signal to the T·231. The signal should pass through the T·231 unaffected because the CHAN 1 and 2 BYPASS buttons are out and the signal processing circuitry is bypassed. 2. Push in the CHAN 1 and 2 BYPASS buttons to enable the graphic equalizer circuits. 3. You can turn up and down each individual slider and hear how it affects the sound. 4. You can turn up and down the input LEVEL controls to make it louder or softer. When the LEVEL control is at the center detent, it is at unity gain (it doesn't boost or cut the signal). CONNECTIONS: 1. Using balanced or unbalanced cables, connect your mixer's main outputs to the T·231's inputs, and the T·231's outputs to your amplifer's (or powered speakers') inputs. If you are using the T·231 in a channel's insert, connect your mixer's channel inserts to your T·231's INPUTs and OUTPUTs. LOOK Note: The T·231 31-Band Graphic Equalizer is designed to be inserted "in-line" with the signal as a serial device. This means that the CLOSER entire signal is routed through the processor, in contrast to a parallel device where the processed signal is mixed back with the unprocessed signal, like a reverb or echo. Things To Remember: · When you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last. · Save the shipping box and packing material! You may need it someday. 2. Connect the cables using either XLR or 1/4" TRS connectors (balanced), or 1/4" TS or RCA connectors (unbalanced). · The XLR, TRS, and RCA inputs for each channel are wired in parallel. Use only one input per channel. · The XLR, TRS, and RCA outputs for each channel are wired in parallel. · The balanced XLR connectors are wired as follows: Pin 1 = shield (ground) Pin 2 = hot (+) Pin 3 = cold (­) · The 1/4" TRS connectors are wired as follows: Tip = hot (+) Ring = cold (­) Sleeve = shield (ground) 3. Plug all the sound system components into suitable AC outlets, properly grounded and capable of delivering adequate current. 4. Turn all the equipment on. If you are monitoring the signal through speakers, turn the power amplifier on last to avoid getting any pops or thumps through your speakers. 4 Contents Safety Instructions................................................................2 Getting Started ....................................................................4 Introduction..........................................................................6 Hookup Diagrams................................................................8 Typical Hookup: In-line with Main Outputs.....................8 Alternate Hookup: Individual Channel or Main Inserts ..8 T·231 Features ....................................................................9 FRONT PANEL FEATURES .................................................9 1.
