REAR PANEL DESCRIPTION

10. Multi Function Dipswitch

Understanding the functionality of the dipswitches is key to maximizing the versatility of the AA35. When a switch is in the up position, the function is "OFF"; when a switch is in the down position, the function is "ON".

1	2	3	4	5	6	7	8
Zone 2 Assign			Mute Rcv		Phantom	Input1	Low cut
Input 3 Input 2 Input 1			Input 3	Input 2
Off	Off	Off	Off	Off	Off	Line/Tel	Off
On	On	On	On	On	On	Mic	On

SWITCH 1- Zone 2 Assign - When "ON", will route signals from Input 3 to the Zone 2 Output terminals.

SWITCH 2- Zone 2 Assign - When "ON", will route signals from Input 2 to the Zone 2 Output terminals.

SWITCH 3- Zone 2 Assign - When "ON", will route signals from Input 1 to the Zone 2 Output terminals.

SWITCH 4 - Mute Receive - When "ON", Input 3 signals will be muted if a signal is present on Input 1 (Refer to Mute Sensitivity Control, number 16 on page 9), or if a contact closure is present on the remote mute terminals (Refer to Remote Mute Connector, number 11(B) on page 8).

SWITCH 5 - Mute Receive - When "ON", Input 2 signals will be muted upon a signal present on Input 1(Refer to Mute Sensitivity Control, number 16 on page 9), or if a contact closure is present on the remote mute terminals (Refer to Remote Mute Connector, number 11(B) on page 8).

1	2	3	4	5	6	7	8
Zone 2 Assign			Mute Rcv		Phantom	Input1	Low cut
Input 3	Input 2	Input 1	Input 3	Input 2
Off	Off	Off	Off	Off	Off	Line/Tel	Off
On	On	On	On	On	On	Mic	On

SWITCH 6 - Phantom - When "ON", applies Phantom Power 24VDC to Input 1 terminals for condenser type microphones. Note: Only use this feature if you are using condenser microphones, otherwise leave in the "OFF" position. This only applies when switch 7 is set to "mic".

SWITCH 7 - Input 1 - When in the "MIC" position, Input 1 will accept microphone level signals; when in the "Line/Tel" position, Input 1 will accept line level or telephone signals.

SWITCH 8 - Low Cut Filter - When in the "ON" position, frequencies below 400Hz are attenuated at the rate of 6dB per octave. Note: The rotary bass control is bypassed when the LOW CUT filter is on. We suggest that when paging horns are connected to the AA35, engage the LOW CUT filter to prevent the horns from operating below their cutoff frequency.

When "OFF", the amplifier operates full bandwidth.

11. (A) Input 1

Balanced mic or line level signals connect to the (+), (—), and (G) terminals. Refer to the chart at the top of the page for the following setting. Dipswitch number 7, labeled Input 1 must be set to the proper position for mic or line level. If you are connecting an unbalanced line level input, tie (short) the (G) and (—) terminals together. If transformer isolation is required for input 1, contact Atlas Sound for details.

(B) Remote Mute Connector

Shorting the Remote Mute terminals, (G) to (M), will mute inputs 2 and/or 3, depending on how their dipswitch settings are set for switch positions 4 and 5 labeled "Mute Rec"/"Input 2" & "Input 3". In the "ON" position, the corresponding channel will be muted when terminals (G) and (M) are shorted together. This connection is usually done via remote switch on a microphone.

12. Input 2

Input 2 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.

13. Input 3

Input 3 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.

14. Zone 2 Output Connector

Use the 1W 8Ω terminals for connection to an external speaker. The 600Ω 1.5V output is typically connected to a PBX music on hold port, also known as MOH.

15. Zone 2 Output Level Control

This rotary control will vary the signal level at the Zone 2 output terminals. Fully counter-clockwise (0) is off, fully clockwise (10) is the maximum output level. The Zone 2 level control is PRE Inputs 1, 2, and 3 volume controls.

16. Mute Sensitivity Control

VOX Mute Sensitivity Control adjusts how sensitive the mute send circuitry on Input 1 reacts. Setting the control fully counter-clockwise will lower the sensitivity, where a higher amplitude signal will be required at Input 1 to trigger the mute send circuits. Fully clockwise will raise the sensitivity of the mute circuits, where a lower amplitude signal will trigger a mute send. Careful calibration of this control may be required to fully utilize the mute circuits capabilities.

17. Line Out A/B

Line Out connectors A/B are paralleled jacks and are useful for providing unbalanced line level signal to another amplifier or other external devices. Prior to using this feature one must understand where the internal signal pick up point is so you can decide if it is correct for your application. We suggest you refer to the block diagram of the AA35 to have a complete understanding of the signal flow.

Note The Following Conditions For Line Out A/B

A. Post Low Cut Filter and is affected when filter is engaged.
B. Post Tone Controls (meaning the settings for the Bass and Treble controls affect this signal output). Note: Refer to Low Cut Filter Switch for complete understanding of the LCF feature.
C. Post Amp In (meaning any signal that is inserted into the Pre AMP In jack will be present at the Line Out A and B).

18. Pre Out

The PRE OUT connector allows Post tone control and low cut filter (when engaged) functions to be available to drive another power amp or external audio device(s). Used in conjunction with the AMP IN connector, an effects loop can be created by connecting the PRE OUT jack to a device such as an equalizer then back out to the AMP IN connector. See Example 3 in the Setup section of this manual.

19. Amp In

The AMP IN connector is useful for converting the AA35 into a slave amp. When a line level signal is connected to this input, the internal connection between the preamp and internal power amp is broken. Audio signals applied to this connector are post tone control and input level controls.

20. Breaker

The circuit breaker is designed to trip and shut down the AA35 "Unswitched Outlet" upon an over current condition. After correcting the cause of the breaker tripping, reset the breaker by pushing in on the tab.

21. Unswitched Outlet

The unswitched outlet provides power for other devices (Atlas rack work light, etc.) and is live whenever the power cord is plugged into a live outlet. Total power draw must not exceed 500W.

22. Output Terminal Strip

For loudspeaker connections, connect as follows or proceed to the setup section for typical wiring schemes.

COM - Speaker common or negative connection

8Ω - Connect to direct coupled loudspeakers

25V - Connect to transformer coupled, 25V loudspeakers with a total load impedance of no less than 17.8Ω

70V - Connect to transformer coupled, 70.7V loudspeakers with a total load impedance of no less than 142.8Ω.

©2006 ATLAS SOUND LP Printed in U.S.A. 000106 ATS002171 RevA 01/06 PP

Setup – Example 2: Small Convenience Store with Gas Pumps

• Connect the paging mic to INPUT 1.
• Set Dipswitches 3 and 7 to "ON". This sets INPUT 1 to mic level input and routes the paging mic to Zone 2 output.
• Connect a digital message repeater to INPUT 2. Note: It is common to connect a CD player to the Input of a message repeater. Now the BGM is routed through the message repeater to INPUT 2.
• Set Dipswitches 2 and 5 to "ON", allowing the message repeater to be routed to the ZONE 2 output and INPUT 2 will receive a mute command from the paging mic at INPUT 1.

- Connected ZONE 2 1W 8Ω output to 4 series/parallel speakers that are wired in the store to providing paging, BGM and digital messages. Note: Room variations and speaker selection will determine number of speakers required. Set the level via the ZONE 2 Level control.

- Connect the gas pump speaker(s) to the 70V output terminals. This will provide paging, BGM, and digital messages to the outside speakers. Note: When paging from the microphone on INPUT 1 the BGM and digital message signal will be muted on the outside speakers allowing only the page to be present.

* Total loudspeaker impedance to be ≥ 8Ω. This output may also be used with 3M ^ pump intercom systems. Contact the factory for details.

Setup – Example 3: Small Speech Privacy Sound Masking System

• Connect a Atlas Sound GPN1200B masking generator to INPUT 1.
• Set Dipswitch 7 to Line/Tel position.
• Connect a 1/3 octave graphic equalizer between to the PRE OUT and AMP IN connectors. This is to tune the system.
• Connect Atlas Sound M1000 masking speakers (up to 30) to the 70V output terminals tapped at 1W each.

Setup – Example 4: MOH with System BGM and Remote Paging

This example has a separate message repeater routed only to the MOH feature of the customer's phone system. While callers are on hold, they hear only custom promotional messages. When a page is present, the BGM will be muted via remote switch on the mic.

• Connect a digital message repeater to INPUT 2.
• Set Dipswitch 2 to "ON", allowing the message repeater to be routed to the ZONE 2 output. INPUT 2 volume control must be turned all the way down, so the audio only goes out the ZONE 2 output and not to the main system.
• Connect a BGM player to INPUT 3 for system background music.
• Connect a paging mic with a switch to INPUT 1.
• Connect the switch wires from the mic to the "RMT MUTE" terminals. Note: The polarity on the switch to the terminals does not matter.
• Set Dipswitch 7 to the "MIC" position.

- Set Dipswitch 4 to the "ON" position. When a page is received via INPUT 1 and the "RMT MUTE" terminals are shorted, the background music (BGM) will mute, allowing the page to be clearly heard. Note: The music on hold (MOH) will not be muted.

- The Mute Sensitivity control must be set fully counter-clockwise to prevent false muting action.

Example 4

WIRING THE AA35

Speaker Outputs - Use 2 conductor unshielded wire of the appropriate gauge. If you are unsure about this, contact Atlas Sound Tech Support at 1-800-876-3333. Make sure you know how many speakers you need and what tap value you intend to use.

Mic/Line Input - Use 2 conductor w/ shield for low level signals of 20-22 gauge is best. Maintain the proper polarity, + to +, - to -, and shield to ground.

Unbalanced Inputs and Outputs - Pre-made RCA cables can be purchased from vendors to simplify interconnection to external devices.

Zone 2 Out - Use 2 conductor, 20-22 gauge, shielded is best. Terminate the shield at the input to the device if possible.

SECURITY COVER OPTION

In order to prevent unauthorized operation of the AA35, optional security covers are available which take the place of the front panel knobs. After the AA35 has been installed and is operating as desired, grasp the front panel knobs and pull straight out from the front panel. Replace the knobs with security covers, Atlas part number AAVCC-5, available in quantities of 5.

Additionally, fuses and lamps carry no warranty.
