Amplifiers

A 1937 • Amplifier Module 250W

These modules are designed for use in emergency evacuation systems and are powered by an external 24V DC source. They accept a line level audio input and produce a 100V line output via a transformer.

Q 2003 • Digital Audio Impedance Meter

An absolute necessity for all PA system installers. This impedance meter for ‘dummies’ designed and manufactured by Altronics calculates and displays speaker loads in watts.

A 4017 • 15W Public Address Amplifier

Super compact with surprising performance specifications, intended for smaller PA system applications. Our engineering team based the design around a National TDA1519 monolithic IC achieving virtually “destruction proof” operation under quite severe misuse such as over temperature, over voltage, over load and short circuit speaker line conditions.

A 4116 • 15W 8 Ohm Stereo Public Address Amplifier

This super compact stereo amp is ideally suited to classrooms, boardrooms, boutiques, reception areas or anywhere a small functional stereo system is required. Offering outstanding stereo performance and featuring both stereo RCA aux and a 3.5mm front panel input, plus a 3.5mm headphone jack.

A 4046A • 100W 4 Input 100V Public Address Amplifier

Designed to meet the requirements of medium sized professional public address installations, this model delivers an output power of 100W offering additional headroom for larger installations with longer strings of 100V line speakers such as schools, factories and supermarkets. Frequency response extends from 60Hz to 15kHz at a total harmonic distortion (THD) of less than 0.5%.

A 4041A • 60W 4 Input 100V Public Address Amplifier

Designed to meet the requirements of medium sized professional public address installations, this model delivers an output power of 60W offering additional headroom for larger installations with longer strings of 100V line speakers such as schools, factories and supermarkets. Frequency response extends from 60Hz to 15kHz at a total harmonic distortion (THD) of less than 0.5%.

A 4036A • 40W 4 Input 100V Public Address Amplifier

Designed to meet the requirements of medium sized professional public address installations, the A 4036A is the next step up from the A 4031B 30W model. This model delivers an output power of 40W offering additional headroom for larger installations. Frequency response extends from 60Hz to 15kHz at a total harmonic distortion (THD) of less than 0.5%.

A 4235 • Compact 1RU Public Address Mixer Amplifier 30W

This compact 1RU rack mount amplifier outputs 30W RMS for 100V line systems. It is suitable for both stand alone PA system use, or as a zone amplifier in a larger system requiring local inputs. Operates on 240V AC or 24V DC for battery backup operation.

A 4245 • Compact 1RU Public Address Mixer Amplifier 60W

This compact 1RU rack mount amplifier outputs 60W RMS for 100V line systems. It is suitable for both stand alone PA system use, or as a zone amplifier in a larger system requiring local inputs. Operates on 240V AC or 24V DC for battery backup operation.

A 4255 • Compact 1RU Public Address Mixer Amplifier 100W

This compact 1RU rack mount amplifier outputs 100W RMS for 100V line systems. It is suitable for both stand alone PA system use, or as a zone amplifier in a larger system requiring local inputs. Operates on 240V AC or 24V DC for battery backup operation.
