Product Description - Model 310M Loudspeaker

Overview:

The Panaray

Model 310M Loudspeaker is a floor monitor intended for smaller indoor applications, such as churches and auditoriums where the model 402, 502A, MA12 and 802 loudspeakers are used for the main system.

The loudspeakers are designed with two specifically designed flat panels that allow the speaker to be used in two different configurations: Vertically positioned at a 40 degree (near field) angle and at a 60 degree angle for far field.

The Panaray Model 310M Loudspeakers are manufactured in black and white.

Enclosure:

The enclosure is a plastic cabinet made of linear low density polyethylene. The volume of the enclosure including ports is approximately 650 cubic inches with approximate dimensions of

14.22x12.52x8.43” (361mmx318mmx214mm).

Drivers:

The Model 310M loudspeakers use three (3) 2.25" drivers and one (1) 5.25" driver. A total of three (3) 2.5" drivers are located in an articulated array with all the dustcaps in a line. Driver 1 is angled at +20 degrees. Driver 2 is angled 0 degrees (straight ahead) and driver 3 is angled at -20 degrees.

The drivers are mounted on the front baffle with four (4) steel powder coated Philips head screws with a thread lock material.

Input Area:

The speaker has two (2) Neutrik® NL4 SpeakOn® connectors mounted on the panel located in a pocket on the rear panel. The input panels are countersunk.

Grille/Logo:

The grille is a perforated pre-coat galvanneal steel grille with a powder coat. The logo is silkscreened onto the vertical band between the two perf patterns. The arctic white variant has an adhered scrim cloth.

Handle:

The speaker is provided with two (2) integral handles for convenient transportation by a single person.

Packaging:

The system packaging consists of the following components:

- One black or white speaker

- Carton

- Owner’s Manual

- One polyethylene bag for cosmetic protection

Product Description - Model 620M Loudspeaker

Overview:

The Panaray

Model 620M Loudspeaker is a floor monitor intended for smaller indoor applications, such as churches and auditoriums where the model 402, 502A, MA12 and 802 loudspeakers are used for the main system. The Model 620M loudspeaker is located on the floor.

The enclosure is designed with three specifically designed flat panels that allow the speaker to be used in three different configurations. Panel one allows for vertical orientation at a 40 degree angle; panel two allows for vertical orientation at 60 degrees; panel three allows for horizontal orientation at a 45 degree angle.

The Panaray Model 620M Loudspeakers are manufactured in black and white.

Enclosure:

The enclosure is a plastic cabinet made of linear low density polyethylene. The volume of the enclosure including ports is approximately 900 cubic inches with approximate dimensions of

20.55x10.39x12.52” (522mmx264mmx318mm).

Drivers:

The Model 620M loudspeakers use six (6) 2.25" drivers and two (2) 5.25" drivers. A total of six (6) 2.5" drivers are located in an articulated array with all the dustcaps in a line. Drivers 1, 3, and 5 are angled at +20 degrees. Drivers 2, 4, and 6 are angled at -20 degrees.

The drivers are mounted on the front baffle with four (4) steel powder coated Philips head screws with a thread lock material.

Page 15

TEST PROCEDURES

1. Phase Test

1.1 Observing polarity, momentarily apply a

12VDC level to pin 1+ and 1- of the Neutrik NL4 connector.

1.2 While applying the DC voltage, observe the drivers. They should all move outward when the voltage is applied. Correct the wiring on any drivers that move inward instead of outward during this test.

2. Rub and Tick Test

2.1 Apply a 10Hz, 20Vrms signal directly to

the terminals of the driver under test. Refer to the disassembly procedures in this manual for the speaker under test to find out how to remove the driver.

2.2 Listen for any extraneous noises such as rubbing, scraping or ticking.

3. System Sweep Test

3.1 Apply a 10Hz, 20Vrms (310M speaker)

or 30Vrms (620M speaker) signal to pin 1+ and pin 1- of the Neutrik NL4 connector.

3.2 Sweep the audio signal generator from 10Hz up to 70Hz.

3.3 Verify that there are no extraneous noises such as buzzes or rattles.

4. Air Leak Test

4.1 Apply a 70Hz, 20Vrms (310M speaker)

or 30Vrms (620M speaker) signal to pin 1+ and pin 1- of the Neutrik NL4 connector.

4.2 Listen for any air leaks around the rear panel, input panel, woofer and handles.

Note: To distinguish between normal suspension noise and rubs or ticks, displace the cone slightly with your fingers. If the noise stays the same, it is normal suspension noise and the driver is fine. Suspension noise will not be heard with program material.
