FAQ - Frequently Asked Questions

Use this as a guide: AmpliVox sound system with 50 watt amplifier and:

• One speaker audience up to 1,000 people; room size up to 10,000 square feet
• Two speakers audience up to 1,500 people; room size up to 15,000 square feet
• Three speakers audience up to 2,000 people; room size up to 20,000 square feet
• Four speakers audience up to 5,000 people; room size up to 25,000 square feet

Although our sound systems are designed to cover audiences up to 1,000 or more, depending on the number of speakers in them, they work equally well with smaller audiences.

Feedback occurs when your microphone is too close to the speakers. To avoid feedback in any sound system the presenter should stand to either side of or behind the speakers. When standing in front, the presenter should leave at least 10 feet between herself and the speakers. You can also turn down the microphone volume.

When wireless sound systems are used within approximately 300 feet of each other, they must be on separate frequencies. Each “Buddy" has 2 built-in frequencies, but different ones can be added. Please call us at 1-847-498-9000 to discuss your special requirements.

Model S1201 is a Dual Module Speaker. It has 2 speakers built into a durable acoustically carpeted cabinet with built-in handle & tripod mount.

The Voice Priority Feature keeps a presenter from worry or inconvenience by automatically lowering music volume when speaking into the microphone. This is a great option for the emcees or the master of ceremonies at a wedding or other public event.

Yes. If you want to plug an iPod, iPhone, smartphone, or other audio device, all you need is a cable that connects to the device and the line in cable. Once you make sure the PA system knows to play the line in audio, you're set!

The Digital Audio Travel Partner PA System's remote is a handy feature that puts control of the 250-watt system in the palm of your hand. With all of the functions the SW915 offers, there are many buttons that can confuse people if they don't use similar technology much. The following video gives a demonstration of each button on the Digital Audio Travel Partner Remote Control and provides instructions.

Since any powerful piece of technology has a bit of a learning curve, watch the video to help with the remote. You will be very happy you did.

If you want to print instructions, go to page 6-7 of the Digital Audio Travel Partner Operation Instructions PDF.

AmpliVox has portable pa systems ranging from 5 watts to 250 watts...which begs the question:

What is a watt?

The watt is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736–1819). The unit, defined as one joule per second, measures the rate of energy conversion.

Both are 50 watt amplifiers with 3 external mic inputs (wireless, condenser, dynamic), 2 external speaker jacks, aux line input with volume and tone controls, and line out to record presentation. Model SW805A includes the extra feature of one built-in wireless receiver with 2 user selectable frequencies.

Yes. The amplifier has two outputs for speakers. You can add up to 4 AmpliVox speakers by adding a Y adapter. The total speaker impedance per channel should not be more than 16 or less than 4 ohms.

First, check your power source:

• If you are powering the system with 10 D-cell alkaline batteries, check each battery to see that it is producing 1.5 volts (15 volts total).
• If you are using the external AC Adapter/recharger (AmpliVox Model S1460), connect it to the jack marked "DC In". The output will be 15 volts, 2 amps, with center positive.
• If you are using our rechargeable system, turn the amp power switch to the "OFF" position, connect the S1465 NiCad Battery Pack to the matching connector inside the amp, and plug in the S1460 AC Adapter/recharger. Leave the amp power switch off until you complete the charging process (8-12 hours or overnight).

Yes. The amplifier has an auxiliary line input. You can connect a CD or Cassette with a cable so that the sound comes through the AmpliVox speakers. You can even control the volume separately from the mic volume because the aux input has itsown volume and tone controls.

Yes, you can connect a computer or video projector using the auxiliary line input.

You can move around in an area up to 300 feet from the amplifier.

Your amplifier, transmitter, receiver, and microphone must be receiving power (either from batteries or AC). See that the amplifier is switched to the ‘ON' position. If you have an SW805A amplifier, make certain that the internal wireless receiver switch is in the ON position. If the transmitter & receiver have selectable frequencies, set them to match each other.

You can add one wireless receiver to the external “Wireless Mic" input. You can aslo add more wireless systems with an external mixer.

No. You need to order the power source you prefer separately. You have a choice of power sources:

• 10 alkaline batteries
• Model S1460 AC Adapter/Recharger
• Rechargeable system (S1460 AC Adapter/recharger + S1465 NiCad BatteryPack)

I only see a place for 5 batteries. Ten fresh alkaline batteries are required to operate the sound system for up to 200 hours. Pull out the battery holder. You will see 5 slots on one side and 5 on the other.

Yes, but it is advisable to remove them if you do not plan to use your sound system with batteries for a period longer than one month. Alkaline batteries can leak corrosive material as they age, which can damage your unit.

You should be able to get up to 200 hours talk time with 10 fresh alkaline batteries. When you use wireless mics, extraspeakers, or sound equipment from the auxiliary line input, you will reducethe battery life.

The rechargeable system consists of Model S1460 AC Adapter/recharger and Model S1465 NiCad Battery Pack.
To install the NiCad Battery Pack:

• Remove the alkaline battery holder and connect the Pack to the matching connector inside the amplifier
• Plug the ACAdapter/recharger into the input labeled “DC IN".
• Then connect the AC powercord into your electrical wall outlet.
• With the amp power switch in the'OFF' position, leave the system plugged in for 8-12 hours or overnight.

Follow the same procedure for subsequent charges after the system has been fully discharged. You should get approximately 20 hours use after charging the battery pack. Avoid recharging the battery pack before it has been fully discharged.

A well-known property of all NiCad batteries is that repeated charging of partially-discharged cells can cause them to develop a 'memory' which will drastically reduce their useful life.

Recharge your system only when the battery pack is fully discharged. Your NiCad Battery pack has to completely run out of power when your AmpliVox sound system will no longer operate. If you want to be prepared for your next presentation but are not sure how many hours of battery life you have left, let your CD or cassette play through the aux line in until there is no more sound.
