• We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety

WARNING
Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

CAUTION
Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

When Installing the Unit

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects — including the unit itself — on the power cord, as doing so may result in fire or electric shock.
• Be sure to replace the unit’s terminal cover after connection completion. Because high voltage is applied to the speaker terminals, never touch these terminals to avoid electric shock.
• Be sure to ground to the safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe as a catastrophic disaster may result.
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down, causing personal injury and/or property damage.

When the Unit is in Use

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest Dayton Audio dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
  • If you detect smoke or a strange smell coming from the unit.
  • If water or any metallic object gets into the unit
  • If the unit falls, or the unit case breaks
  • If the power supply cord is damaged (exposure of the core, disconnection, etc.)
  • If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest Dayton Audio dealer.
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
• Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as this may result in fire or electric shock.

When Installing the Unit

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.
• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
• When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock. When removing the power cord, be sure to hold its plug to pull.
• Do not block the ventilation slots in the unit’s cover. Doing so may cause heat to build up inside the unit and result in fire.
• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

When the Unit is in Use

• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
• Make sure that the volume control is set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.
• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire.
• Contact your Dayton Audio dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of time, a fire or damage to the unit may result.
• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.
• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

Due to product upgrades, some of the features and specifications in the user manual do not match the actual functions. Sorry for any inconvenience and thanks for your kind understanding!

Setup

Unpacking Your Amplifier
Before installing your amplifier, please unpack and inspect it for any damage that might have occurred during shipment. Verify that all accessories are included in the box. If you notice damage or that parts are missing, please contact Dayton Audio for assistance.

Warning: Please read and observe the safety instructions at the beginning of the manual before setting up your amplifier

Installing Your Amplifier

Ensuring Proper cooling
Be sure to keep all sides of the product clear and free of objects that may obstruct the air flow and prevent proper cooling of the amplifier. It is best to keep 4” of clearance on all sides.

Input Wiring
Using high quality balanced 22-24 gauge cable, connect to the balanced inputs by using the included Phoenix style connectors. Shielded cable will provide the best results. Unbalanced or unshielded cable may result in RF noise or a Hum in the input signal. You can also connect devices such as CD players, computers, or streaming devices using the available Stereo RCA connecti ons. The stereo signal will be summed to mono for both the amplifi er and line level outputs

Note: Do not use the RCA input on a single channel at the same ti me as the Phoenix style input.

Output Wiring
Connect passive speakers to the output terminals on the rear of the amplifi er. To avoid damage to the amplifi er or speakers, be sure the 70V/4-16Ω is in the correct positi on for your system.

It is recommended that high quality, heavy gauge, two conductor twisted speaker cable is used when connecti ng your loudspeakers. 14-16 AWG wire will work in most applicati ons

Connecting to AC Mains
Connect your amplifi er to mains power using the supplied AC power cable to a grounded outlet. The third prong of the AC power cable is important and necessary for safe operati on of your amplifi er. Do not att empt to disable the ground connecti on.

Bluetooth Pairing
To pair a Bluetooth device to the built in media player, press and hold the mode button to activate pairing mode and search for “BP10_BT” on your Bluetooth device.

Input Level Control
Each input channel has the ability to accept line and microphone signals and can also supply phantom power to microphones when necessary. Set the level control switch on each channel according to the source that is connected. Improperly setting this switch could result in the signal being too quiet or being distorted.

VOX Function
Audio activated ducking is a useful feature that can mute other channels when audio is present on Channel 1. Adjusting the “Mute” knob on the rear of the amplifier will control how much audio is required to mute the other inputs. Turning “mute” all the way down (counterclockwise) will disable this function.

Priority and EMC Muting
Channel 1 can also be used as a priority channel. All other channels can be immediately muted when pins 3 and 4 on the priority muting interface connector are shorted using an external switch or the button of adedicated paging microphone The Amplifier also has the ability to accept Emergency Control Muting (EMC) from capable safety systems, muting all output from the amplifier. This feature can be activated by shorting pins 1 and 3 on the priority muting interface connector.

Output Level Control
Set the main volume output with the Master Volume knob. Avoid overpowering the connected speakers as too much power can distort and damage loudspeakers over time. The built in limiter and protection circuit acts as a safeguard against clipping and short circuits.

Aux Output
The Aux audio output is a mono mix of all signals. The master volume output and tone controls will have no affect on the aux output signal.
