Frequently Asked Questions - ANS501 Bogen

What is the Bogen ANS501 used for?

The Bogen ANS501 is a public address amplifier designed for paging, background music, and voice announcements in commercial or educational settings.

How do I connect speakers to the ANS501?

Use the 70V/100V speaker outputs for distributed systems, or connect 4-16 ohm speakers directly to the low-impedance terminals. Ensure total load does not exceed amplifier rating.

The amplifier has no sound output. What should I check?

Verify the power cord is connected and the power switch is on. Check the volume controls, input connections, and ensure no mute is active. Also inspect the fuse and replace if blown.

Can I use the ANS501 with a 100V system?

Yes, the ANS501 supports both 70V and 100V distributed audio systems. Select the appropriate output tap on the speaker transformers.

How do I set priority muting?

Input 1 (Mic 1) automatically mutes other inputs when a signal is detected. This is used for emergency announcements. Adjust the priority threshold if needed via internal trimmer.

What type of microphone can I use?

Use a dynamic microphone with XLR connector. The input impedance is suitable for most dynamic mics. Phantom power is not provided.

How do I clean and maintain the amplifier?

Disconnect power before cleaning. Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Ensure ventilation slots are unobstructed.

What are the dimensions for rack mounting?

The amplifier occupies 2U rack space (3.5 inches high). Use the included rack ears for installation in a standard 19-inch rack.

Is the ANS501 compatible with background music sources?

Yes, connect a line-level source (e.g., CD player, tuner) to the RCA line input. Adjust the line volume control to blend with microphones.

Where can I get replacement parts or service?

Contact Bogen's authorized service center or visit the Bogen website for a list of service locations. Common parts like fuses are available from electronics distributors.

The Bogen Model ANS501 Ambient Noise Sensor is designed to electronically adjust the level of a page announcement or background music in an area of a building where ambient noise levels are continuously changing. It ensures that page announcements or background music are intelligible even during periods of high ambient noise levels.

The ANS501 monitors the ambient noise level through the use of an ANS500M sensor microphone module. Each sensor microphone module includes an adjustable mounting base for precise positioning.

One microphone and one power supply are included with the ANS501. Additional microphones may be purchased separately. The control unit is capable of supporting up to four (4) microphones wired in parallel. Wire runs between the control unit and microphones consist of two-conductor cable and can reach 2,000 feet (with 20AWG wire) with no appreciable loss of signal strength.

Front Panel Controls

AUX Level Control

Controls the AUX input level, which is bussed directly to the output. Aux signal bypasses gain riding.

Relative Gain Control

Sets the relative amount of gain maintained above the ambient level. Range is 1 dB to 24 dB of gain.

Ramp Speed Control

Sets the speed by which gain is increased/decreased to the signal once the ambient noise level is above/below the threshold, from less than 1 dB/s (slow) to greater than 20 dB/s (fast).

Maximum Boost Control

Sets the maximum amount of gain. Range is 1 dB to 22 dB of gain.

Threshold Controls

Activity threshold is set just above typical operating level of the program material applied to the gain processing stage of the ANS501. Ambient threshold adjusts the ambient noise input threshold from 64 dBspl to 112 dBspl.

Front Panel Switches and Indicators

Mode Switch

The Mode switch can be set to "Run" (for normal operation) or "Set"(for set up).

Status LED

Bi-color LED illuminates when different thresholds are triggered to assist in setup. Green indicates "+" gain. Amber indicates "-" gain.

AUX Input

High-impedance, electronically balanced, pluggable screw terminal input. Signal gain responds to ambient noise changes.

High-impedance unbalanced RCA input. Signal gain responds to ambient noise changes.

Connections to ANS500M sensor microphone(s) are made here. The input is a pluggable screw terminal input.

The effects of the ANS501 will be defeated when these terminals are shorted together. The input is a pluggable screw terminal input.

Low-impedance electronically balanced, pluggable screw terminal output. Signal gain responds to ambient noise changes.

Low-impedance unbalanced RCA output. Signal gain responds to ambient noise changes.

Mono summing, stereo, unbalanced RCA inputs. This input bypasses the gain adjustment process of ANS501 and is fed directly to the output, via the AUX level control.

All inputs (balanced and unbalanced) into the ANS501, with the exception of the Aux input, will be affected by the automatic gain adjustments of the ANS501.

In audio systems that provide continuous background music, it may be desirable to have the background music stay at a fixed level but have all other source inputs (like a paging microphone) change level in response to the ambient noise level in an area. Background music is typically provided to make a venue seem less empty during slow periods or to help mask conversation during quiet times. It is often undesirable to have the background music level increase as ambient noise increases since it only adds to the overall noise in the area. The ANS501 provides an Aux input that bypasses the gain adjustment process so that it does not change with ambient noise levels.

Bypass Mode

Background music bypasses the gain adjustment process. Refer to page 11 for illustration.

Start with all POTS turned fully clockwise (except AUX LEVEL, which should be fully counterclockwise).

1. Connect the background music source to the ANS501's RCA Aux IN jacks.

2. Set the background music to the desired operating level using the AUX LEVEL control.

3. Set MODE Switch to "SET" mode.

4. Set RELATIVE GAIN to the desired amount of signal gain you would like the balanced/unbalanced input to ride over the ambient level.

5. Set MAX BOOST to limit the maximum amount of signal gain for the whole system.

6. Adjust AMBIENT THRESHOLD until the STATUS LED starts flashing amber, then adjust ACTIVITY THRESHOLD until amber stops flashing.

7a. Using the chart and diagram on page 13, set the AMBIENT THRESHOLD to the dBspl level where automatic increases to the system volume would be desired, then set the MODE Switch to the 'Run' position. - or -

7b. If the live ambient noise level (while making these adjustments) is at the desired trip point, set the MODE Switch to the 'Run' position, and then adjust the AMBIENT THRESHOLD control to a point where the STATUS LED flashes green.

1. Adjust RAMP SPEED to desired settings.

2. Test the system's response to noise and, if necessary, set the ACTIVITY THRESHOLD control higher if the maximum signal level is not achieved. Tweaking adjustments to MAX BOOST, RELATIVE GAIN, and RAMP SPEED controls may also be necessary.

Normal Mode

All sources are affected by the gain adjustment process. Background music source will need to be routed through the main mixer inputs, which will be affected by the gain adjustment process. Refer to page 12 for illustration.

Start with all POTS turned fully clockwise (AUX IN is not used in this mode).

1. Set MODE Switch to "SET" mode.

2. Set RELATIVE GAIN to the desired amount of signal gain you would like the balanced/unbalanced input to ride over the ambient level.

3. Set MAX BOOST to limit the maximum amount of signal gain for the whole system.

4. Adjust AMBIENT THRESHOLD until the STATUS LED starts flashing amber, then adjust ACTIVITY THRESHOLD until amber stops flashing.

5a. Using the chart and diagram on page 13, set the AMBIENT THRESHOLD to the dBspl level where automatic increases to the system volume would be desired, then set the MODE Switch to 'Run'. - or -

5b. If the live ambient noise level (while making these adjustments) is at the desired trip point, set the MODE Switch to the 'Run' position, and then adjust the AMBIENT THRESHOLD control to a point where the STATUS LED flashes green.

1. Adjust RAMP SPEED to desired settings.

2. Test the system's response to noise and, if necessary, set the ACTIVITY THRESHOLD control higher if the maximum signal level is not achieved. Tweaking adjustments to MAX BOOST, RELATIVE GAIN, and RAMP SPEED controls may also be necessary.
