DAYTON AUDIO DA60R (01) PDF DOCUMENT

Please observe the following safety warnings for your DAYTON AUDIO DA60R:

When Installing the Unit:

• Do not expose this product to rain or an environment where it could be splashed by water or other liquids.

• Only use this product with the voltage specified. Using higher voltage may result in fire or electric shock.

• Do not cut, kink, damage or modify the power cord. Avoid using the power cord in close proximity to heaters, and never place heavy objects on the cord. This could result in electric shock or fire.

• Be sure to replace the speaker terminal cover after the connections are complete. High voltage is applied to the speaker terminals. To avoid electric shock, never touch these terminals.

• Be sure you ground the amplifier using the safety ground (earth) terminal to avoid electric shock. Never ground this product to a gas pipe or other flammable items.

• Avoid installing or mounting this product on an unstable or slanted surface. Doing so may cause the unit to fall, resulting in personal injury or property damage.

When the Unit is in Use:

• To prevent a fire or electric shock, never open or remove the product cover; there are high voltage components inside. Refer all servicing and repair to your nearest Dayton Audio dealer.

• Do not place cups, bowls, or anything containing liquid or metal objects on top of the product.

• To prevent fire or electric shock, do not insert metal objects or flammable materials in the cover or vents of this product.

Should any of the following issues occur during use, immediately switch off the power and disconnect the power cord from the AC outlet. Make no further attempt to operate the malfunctioning product, doing so may cause fire or electric shock. Contact your Dayton Audio dealer for service and repair.

1. If you detect smoke or a strange smell coming from the unit.

2. If any liquid or metal gets inside the product.

3. If the product is dropped or falls and case is broken.

4. If the power cord is cut or damaged.

5. If the sound becomes distorted.

When Installing the Unit:

• Never plug in or remove the power cord with wet hands, doing so may cause electric shock.

• When unplugging the power cord, be sure to grasp the power cord plug; never pull on the cord itself. Operating the unit with a damaged power cord may cause a fire or electric shock.

• When moving the unit, be sure to remove the power cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord or cause you to accidentally drop the product, resulting in personal or property damage.

• Do not block the ventilation areas in the cover. Doing so may cause heat to build up inside the unit, resulting in product failure and possibly fire.

• Avoid installing the unit in humid or dusty locations, direct sunlight, near heaters or in locations generating sooty smoke/steam.

• Do not place heavy objects on top of the product. This can result in the product or object to fall, causing personal injury or property damage.

General Cautions:

• Before powering on the product make sure that the master volume control is set to the lowest setting. Loud or high volume noise can damage or impair hearing.

• Do not operate the unit if the sound is distorting. This is an indication of a product malfunction, immediately unplug the power and contact your Dayton Audio dealer for service or repair.

• Dust allowed to accumulate inside the product could result in fire or electrical damage. Be sure to consult your Dayton Audio dealer for cleaning service and repair. Periodically clean dust buildup from the power cord plug and wall outlet to avoid electrical fire. Ensure the power cord plug is securely inserted in the wall outlet.

• For safety when cleaning or leaving the unit unattended for long periods of time, switch the power off, unplug the power cord plug from the wall outlet. Doing otherwise may cause a fire or electric shock.

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in the electrical installation of the building.

1. Rated Power: 60W/120W.

2. 100V, 70V constant voltage outputs and 4~16 ohms constant resistance output.

3. Commercial-grade toroidal transformers produce high performance audio on a wide range of frequencies with minimum noise and high fidelity, even at high volume.

4. Protection against overload, short circuit, and power fluctuation for optimum reliability.

5. VOX feature mutes AUX inputs when input is detected on MIC 1. Time Adjust control allows resumption of music to be sharp or gradual.

6. Phantom power available on MIC 1 input for condenser-type microphones.

7. TEL priority: TEL override AUX1-2 and MIC(2-3).

1. MIC1 INPUT: MIC1 1/4″ phone jack input.

2. MIC1/MIC2/MIC3: MIC volume control for each respective channel.

3. AUX1/AUX2: AUX volume control for each respective channel.

4. TEL: TEL volume control.

5. BASS: Bass response adjustment. Rotate clockwise to increase bass output and counterclockwise to reduce it.

6. TREBLE: Treble response adjustment. Rotate clockwise to increase treble output and counterclockwise to reduce it.

7. MASTER: Master volume control.

8. POWER SWITCH: ON/OFF toggle switch.

9. POWER: Power indicator light.

10. LEVEL INDICATORS: Signal output level indicators.

11. PROT: Protection mode status indicator. This indicator will illuminate if the product is in protection mode due to overheating or overload.

12. TEMP: High temperature status indicator. Indicator will be illuminated if the temperature inside the unit becomes too high for normal operation.

13. ~110V 60Hz POWER INPUT: AC power input.

14. SPEAKER TERMINALS: Connectors for 4-16 ohms or 70V and 100V speakers.

15. Mute adjustment: Adjusts the mute level from 0-20 dB during signal override of all channels by MIC1 input.

16. MIC1 input: Compatible with XLR and 1/4″ phono plugs.

17. Phantom power ON/OFF switch: Enables or disables phantom power for MIC1.

18. (MIC2/MIC3) MIC input: MIC 2-3 inputs, 1/4″ Phono plug.

19. TEL INPUT: Ground, Negative, Positive terminal block for telephone paging input.

20. (AUX1/AUX2) AUX input: Auxiliary inputs for additional audio equipment.

21. LINE OUT: L/R RCA outputs for sending audio to additional equipment.

You can connect speakers using the screw terminals on the rear panel. There are three types of connections:

• 4-16 Ω: For standard low-impedance speakers. Connect to the ‘COM’ and ‘4-16Ω’ terminals.

• 70V LINE: For 70V constant voltage speaker systems. Connect to the ‘COM’ and ’70V’ terminals. The total speaker system (load) impedance should be 81Ω for the DA60R or 41Ω for the DA120R.

• 100V LINE: For 100V constant voltage speaker systems. Connect to the ‘COM’ and ‘100V’ terminals. The total speaker system (load) impedance should be 167Ω for the DA60R or 83Ω for the DA120R.

Notes:

• The 4-16 ohm and 70V/100V terminals cannot both be used at the same time.

• Impedances indicated in the figures represent the total speaker system (load) impedances.

WARNING: Be sure to replace the speaker terminal cover after speaker connections have been made.

The DAYTON AUDIO DA60R uses a combined XLR (female)/phone jack connector for MIC1. The pin configurations are as follows:

XLR type male connector:

• Pin 1: Ground

• Pin 2: Hot

• Pin 3: Cold

Phone plug (1/4″):

• Sleeve: Ground

• Ring: Cold

• Tip: Hot

You can choose only two of the four output connectors to work together. If the voltage is 70V/100V, the speakers must have a transformer. Make sure the total power wattage of the speaker system is 15% less than the power wattage of the amplifier.

1. TEL has priority over all inputs.

2. MIC 1 is second priority. Adjusting the mute level control on the rear panel can override all other input signals except for the TEL signal.

Keep all sides of the product clear and free of objects that may obstruct the air flow and prevent proper cooling of the product. It is recommended to maintain a clearance of over 100 mm on the top, left, and right sides of the unit.
