Introduction

The OWI AMP-ER2TR6 is a multi voice coil, self powered speaker/amplifier. It is a two source/input speaker with ER paging override. This unit can drive up to four speakers connected series parallel to have a net impedance of 8 ohms. With an included UL Listed, Level 5 (Energy Star), 15 volt, 3.5 ampere power supply, the amplifier can output 40 watts, or 10 watts per speaker in a four speaker hook-up.

OWI User Manual: Model AMP-ER2TR6

Energy Star Sleep Mode

If no audio is present on any input of the power amplifier, the amplifier goes into a low power "shutdown, or sleep mode" within 30 minutes. During sleep mode, power consumption of the power supply and the amplifier is less than one (1) watt.

Two (2) audio inputs: Line In and Jack Line In

The LINE IN inputs accepts a balanced input via a Phoenix style screw terminal plug. The JACK LINE IN accepts unbalanced input via 3.5 mini jack. The mini jack accept stereo inputs. The stereo channels are summed together. This input is muted during Priority Override.

Priority Override Feature

The Priority input accepts balanced input levels of resistor selected 100 volts audio, 70 volts audio, 25 volts audio and 1 volt (approximately line level) audio. Audio on the Priority input suspends audio on the Line In and Jack Line In inputs and switches the speaker amplifier to pass the Priority audio. After the Priority audio stops, the unit waits before returning to the Line In and Jack Line In audio input.

Balanced Line Level Output

A nominal 0dB level, balanced output is available at LINE OUT. The source of this output is both balanced and Jack Line In sources.

Power Amplifier Features

The power amplifier outputs 2 times 20 watts or 40 watts total into 8 ohms and 15VDC power. The class D power amplifier has reduced radiated electromagnetic interference (EMI) due to a special feature of the power amplifier, operating in a patented spread spectrum. The power amplifier protects itself from over-temperature, over-current, over-voltage conditions. The power amplifier will shut itself down during these conditions.

   *Note: Quantity of Ceiling speakers, tile bridge and backcan depends on the SKU of the AMP-ER2TR6 Combination Program.

Speaker Placement

Before installing your OWI speakers, consider the placement carefully, taking into effect the location of electrical, plumbing and other fixtures.

Placement in Ceiling

OWI speakers should be located above the primary listening area.

Mounting your OWI speakers

Determine the best area to mount your OWI speakers. It will be necessary to run your speaker wires to that location. This location must be free of obstructions, such as electrical conduits, HVAC ducts, or water lines.

Be sure the mounting surface is between 3/8 and 1 14 inches thick and that there is at least a 3 inch clearance behind the mounting surface (5 inch if using an OWI backcan). Make sure that no objects block the back of the speaker.

Remove the round cardboard disc from the template supplied and keep it for later use as a paint mask, if you decide to paint your speakers.

Use the template to mark the position for the mounting hole at the selected location. If you are not certain that no obstruction exists (electrical wiring, plumbing, etc.), you should start by cutting a small hole in the center of your penciled mounting hole with a drywall or keyhole saw, cutting at a 45 degree angle towards the inside of the hole. Cutting a small hole at this angle will make drywall repair much easier. Once you have determined there are no obstructions in your desired mounting location, start cutting the finished hole at a 90 degree angle to the ceiling surface.

Route the speaker wires from your amplifier to your opening. Avoid routing the speaker wire near electrical wires. If you have to run them parallel, make certain to space the speaker wires at least 2 feet from the AC line. Do not nail or staple the speaker wire.

OWI User Manual: Model AMP-ER2TR6

Prepare Your OWI Speakers for Mounting

Insert a paper clip into one of the grille openings, then pull upwards to remove the grille.

Turn the mounting tab 90° and push toward the grill. The grill will safely pop off.

Paper clip Grill Push clamp

Mounting tab

Be sure to position the four Mounting Tabs on your OWI speaker inward then insert the four (4) screws (supplied) from the front of the speaker into the screw opening.

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), if the GT contains lines used for stylistic emphasis or as background (like ruled paper), the OCR result must ignore them. The provided OCR content is "____", which consists of four underscores. This is incorrect because underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a stylistic line violates the rule and constitutes an error. Therefore, the OCR result is inconsistent with the Ground Truth.

The Ground Truth image displays a single, solid horizontal line, which is a stylistic or background element (like a ruled paper line or separator), not a placeholder for text. According to Rule 2, such stylistic/background lines must be ignored by the OCR result. The OCR content provided is "", which consists of no characters. This correctly represents the absence of any textual content in the GT and correctly ignores it as a hallucinistic visual element. Therefore, the OCR output should have been empty or omitted this line entirely.
