REAR PANEL DESCRIPTION

9. Dipswitch "A" Positions 1-6

Understanding the functionality of the dipswitches is key to getting the most out of the AA120/AA240. Whether the switch is in the "Up" or "Down" position is critical to the function of the amplifier. Note: Mispositioning any of these switches may cause harm to the speakers or amplifi er. We recommended all levels be turned down prior to making any switch selections. Pay close attention to the two assignment charts and manual for proper settings.

1	2	3	4	5	6
Low Cut	Input 6	Input 5	Input 4	Input 3	Input 2
	Mule Rcv
Off	Off	Off	Off	Off	Off
On	On	On	On	On	On

Dipswitch 1- LOW CUT – 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 fi Iter is on. We suggest that when paging horns are connected to the AA120/AA240, engage the LOW CUT filter to prevent the horns from operating below their cut off frequency. When "OFF", the amplifi er operates full bandwidth.

Dipswitch 2-6 - MUTE RCV (RECEIVE) – When "ON", Input's 2-6 signals will be muted upon a signal present on Input 1 (Refer to Number 11 Input 1 Sens), or a contact closure on the remote mute terminals (Refer to Number 15 Remote Mute).

10. Dipswitch "B" Positions 1-8

1	2	3	4	5	6	7	8
Input 6	Input 5	Input 4	Input 3	Input 2	Input 1	Phantom	VCA
Sens
100mV	Line	Line	Line	Line	Tel/Line	Off	Master
300mV	Mic	Mic	Mic	Mic	Mic	On	Input 6

Dipswitch 1 – When set to the "100mV" position, the sensitivity of Input 6 is suitable for inputting Telephone Paging Signals. When set to the "300mV" position, the sensitivity of Input 6 is suitable for CD/DVD player outputs.

Dipswitch 2-5 - When set to the "Line" position, input sensitivity is suitable for CD/DVD line level outputs. When set to the "Mic" position, sensitivity is suitable for microphone inputs.

Dipswitch 6 - When set the "Tel/Line" position, Input 1 sensitivity is suitable for telephone paging and line level signals. When set to the "Mic" position, the sensitivity is set for microphone signals.

Dipswitch 7 - When set to the "OFF" position, PHANTOM POWER is turned off on INPUTS 1-5. When set to the "ON" position, PHANTOM POWER (24VDC) is available on INPUTS 1-5 (mic position only).

Dipswitch 8 - When set to the "Master" position, the VCA control port acts as a over all system remote volume control, adjusting all the input channels present on the master section mix bus up or down simultaneously. When set to the "Input 6" position, the VCA remote control port affects only the level of INPUT 6.

11. Input 1 Sens

This control adjusts how sensitive the mute send circuitry on INPUT 1 reacts. Setting the control fully counter-clockwise will lower the sensitivity, and 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. Adjustment of this control should occur after the input trim (12) for channel 1 is set.

12. Inputs 1-5 Trim

These variable controls allows fi ne tuning of the gain of INPUTS 1 – 5. There is 20dB of variable gain available. The trim only applies when the input is set to the "Mic" position on the dipswitch.

13. Zone 2 Level

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 output gets its signal from INPUT 6, volume control.

14. VCA

Remote location of the level control can be accomplished via the VCA control port. You can control the overall level (Master) or just Input 6. This selection is made via Dipswitch "B" position #8. Connect the two leads from the optional remote volume control to these terminals. This remote level control is POST Master and Input 5 Level Controls. Set the system's maximum levels using the amplifier level controls and then use the remote VCA potentiometer as an attenuator from the maximum levels set. See the VCA setup section for instructions on wiring the potentiometer.

15. Remote Mute

The Remote Mute feature is useful when the background system needs to be muted from a remote location. When shorting the Remote Mute terminals together, (G) to (M), the assigned channels will be muted. Note: Input 1 cannot be VOX or remote muted at anytime. Dipswitches 2-5 settings determine which inputs are to receive the Mute trigger. To trigger the mute it is common to use an external contact closure or switch on a microphone.

16. Zone 2 Output - 600Ω

The 600Ω 1.5V (Zone 2 Out) output is typically connected to a PBX MUSIC ON HOLD port, also known as MOH. The ZONE 2 output gets its signal from INPUT 6, volume control.

17. Zone 2 Output - 1 Watt 8Ω

The 8Ω 1W Zone 2 output can drive an external 8Ω speaker, and is taken Pre input 6 gain control. Use the 1W 8Ω terminals for connection to an external speaker.

18. Bridge In/Out

Certain installations have the need to combine one or more mixers together. These mixers may be in different rooms of an install but have the need to share a page or music throughout the installation. These terminals provide a way to send and receive balanced line level signals from the internal mix bus of the AA120/AA240. The "BRIDGE IN/OUT" feature is PRE Tone Controls and Low Cut Filter The Bridge In/Out feature allows you to send and receive a balanced signal. This is important for allowing longer distances between the mixers. Note: This function should only be used with other Atlas Sound mixers that have this feature. The Send and Receive signals are combined through the same terminals. To activate this feature, see number 19 Bridge Select.

19. Bridge Select

The "Bridge Select (Sel)" terminals are the access point to activate the "Bridge In/Out" feature. To activate the feature connect the two points together via an external contact closure. These two points must be connected to send or receive any signal. By connecting the Bridge In/Out terminals of two AA120/AA240's, a simple room combining system can be accomplished. If using a remote switch and closing it, the "Bridge Select (Sel)" will combine the amps as one, opening the switch will separate the two amps. Note: If combining 3 or 4 mixers together the output level will have to be adjusted before and after Bridge Sel terminals are connected (shorted) together. We suggest utilizing the Remote Level control when using this feature.

Sens
100mV	Line	Line	Line	Line	Tel/Line	Off	Master
300mV	Mic	Mic	Mic	Mic	Mic	On	Input 6

20. Input 1

Balanced mic or line level signals connect to the (+) (−) and (G) terminals. Refer to the chart above "Multi Function Dipswitch" for the following setting. Dipswitch 6, labeled Input 1 must be set to the proper position for mic or Tel/Line level. If you are connecting an unbalanced line level input, tie (short) the (G) and (−) terminals together. An optional Input Isolation Transformer is available if a ground loop problem exists. See page 20 for transformer installation. Contact Atlas for more details on the Input Isolation Transformer.

Note: Input 1 cannot be muted from other channels. This channel is the VOX mute send to the other inputs that are set to Mute Receive. The sensitivity and threshold for the VOX send works in conjunction with the Input 1 Trim and the Input 1 Sens.

21. Inputs 2-5

Inputs 2-5 are balanced, line or mic level (Refer to Dipswitch Bank 1-8 for setting input sensitivity). For wiring unbalanced inputs, tie (short) the (G) and (−) terminals together.

22. Input 6

INPUT 6 consists of a pair of stereo summing, line level inputs. Connect unbalanced audio outputs here such as CD players or audio from DVD players.

23. Line Out A/B

The LINE OUT connector is 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 AA120/AA240 to have a complete understanding of the signal flow.

Note the following conditions for LINE OUT

A. Pre Low Cut Filter

B. Post Tone Controls (meaning the settings for the Bass and Treble controls affect this signals 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).

24. Tape Out A/B

Line level mono signals are available at this jack for connection to recording devices. The signal available here is PRE tone control and low cut filter and comes from the internal mix bus.

25. Pre Out

The PRE OUT connector has Post tone control signals available to drive another power amp or external audio devices. Use 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 the connection diagram in the setup section of this manual.

26. Pwr In

The AMP IN connector is useful for converting the AA120/AA240 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. The AA120/AA240 is now just a power amplifier, amplifying audio signals applied to this connector.

QUICK START EXAMPLES

Example 1 — System Paging, BGM, and MOH with Remote Master Level Control

This application has the paging microphone into INPUT 1, BGM (CD player) into Input 2, and a Message Repeater or MOH into Input 6. The Zone 2 Output is sent to the telephone system's MOH input port. A level control is placed in another area such as a front desk to adjust the system's level without having to go the equipment room. When a page comes through Input 1, the BGM is muted allowing only paging to be heard through the main system. The MOH is not affected during the page.

- Connect a paging mic to INPUT 1. Set Dipswitch "B" #6, "Input 1" to the "Mic" position. Note: The INPUT 1 Trim and Sens will need to be adjusted after all the settings and connections have been set.

- Connect a BGM (CD) player to INPUT 2.

- Set Dipswitch "A" #6, "Mute Rcv" to the "ON" position.

- Connect a Message Repeater or MOH device to INPUT 6. Note: The input gain of this channel may need to be change for proper level balance. Dipswitch "B" #1, "Input 6" allows you to select between a 100mV or 300mV input sensitivity. Turn down channel 6 gain control on the front panel.

- Connect Zone 2 output to the MOH input on your telephone. Adjust the Zone 2 Output level as needed.

Example 2 - Hotel Room Combining Using Two AA120s/AA240s

This example utilizes the combining feature of the Atlas AA120/AA240 mixer amplifiers. The drawing below shows the equipment connections for two hotel ballrooms, separated by a moveable air wall. The hotel needs to be able to have the audio system operate as one large unit (air wall open) or two discreet systems (air wall closed). As indicated in the example, a BGM CD player is shared between the two AA120s/AA240s, via a "Y" cable, connected to input 6 of each mixer amp. The Bridge terminals of both amplifiers are connected together, through a DPST switch that makes (combines) or breaks (separates) the Bridge connections between the amplifiers. When the switch is closed, any audio signal into either amp will be present at both amplifier's speaker outputs. A volume control and DPST switch (see drawing for clarity) controls the background music level and turns the music on or off in each room. For emergency evacuation purposes, a signal from the hotel's fire alarm system is connected to channel 1 of both amplifiers, with the mute sensitivity adjusted as needed. All other channels are set for mute receive and will mute when the siren tone is present on channel 1.

WIRING THE AA120/AA240

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. For unbalanced signals, connect the (G) to the (—) terminal.

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 COVERS OPTION

In order to prevent unauthorized operation of the AA120/AA240, optional security covers are available which take the place of the front panel knobs. After the AA120/AA240 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.

WIRING THE AAVCC-10K VCA POTENTIOMETER -

Atlas part number, AAVCC-10K, consists of a single gang "Decora" style wall plate with a pre-mounted 10K potentiometer and knob.

Use two conductor unshielded wire connecting the pot terminals to the terminals marked "VCA" on the back of the amp.

RACK MOUNT KIT

For permanent mounting of the AA120/AA240 into equipment racks, order part number AARM-2RU. If multiple units are being rack mounted, install Atlas 1RU (SVP19-1-052) vented panels between amplifiers in order to aid cooling.
