| Content | The APart MA35 is probably the most complete and compact 35 watt 100 Volt mixing desktop amplifier. The amplifier has 4 inputs: 2 MIC, 1 MIC-LINE and 1LINE. The microphone inputs can have phantom power via an internal jumper. A two step priority system is standard: MIC1 can have voice activated priority (VOX) that mutes all other inputs. This VOX mute can be switched off via an internal jumper. The contact closure (via DIN5 on MIC1 or Euroblock on MIC1-2) will activate the chime and will mute input 3 (MIC3/LINE3) and 4.
The pre-amp out, power-amp input allows you to insert extra signal processors or to link the signal to other power amplifiers. Further the MA35 is equipped with a bass - treble tone control, a record output and limiter circuit on the output to avoid clipping. MA35 can operate with a 12V and 230V power supply. The amplifier has been build into a compact and sturdy metal housing. A 19” mounting bracket (Ref: MA35-19) is available as an option for rack mounting. | With the MA200 mixing amplifier series, the APart engineering team has created some unique, original and above all, complete electronics. Never before has a mixer amplifier had all the features to meet a contractors demand for nearly every application.
- The most important features:
- 200 watt 100 Volt mixing amplifier
- 4 mic inputs (phantom via internal switch)
- Mic inputs have integrated speech filters and are high-class transistor balanced
- 4 Line inputs
- 4 Loudspeaker output zones can be selected (switch on/off) and have LED indication. Zone 4: selection of "Music only”, "microphone only” or both music and microphone.
- Bass-treble tone control
- Master volume control
- 3-Level priority system:
- 1. Emergency input: directly to the power amplifier (vol adjustable)
- 2. VOX Mute: Voice activated mute (adjustable) on MIC input 1 mutes all other inputs
- 3. Contact closure mutes all line inputs
- LED indication on front pannel when line inputs are muted
- 24V ouput power is activated via contact closure. Can be used to switch the 24V priority
- relays of volume controls.
- Integrated 2-tone chime has an adjustable volume and is activated by contact closure
- Build-in dynamic limiter (-3dB)
- Record output via RCA
- PRE AMP OUT - AMP IN makes it possible to insert an external signal processor or to add
| REVAMP4240T is a professional 4-channel digital power amplifier with 4 x 240 watt output power @ 100 volt, but the unit is also bridgeable to 2 x 480 watts @ 100 volt. The unit incorporates a high efficient SMPS power supply and outputs with efficient Class D output topology. REVAMP4240T is the ideal amplifier for applications with 4 zones in mono, 2 zones in stereo or even bridged dual mono or bridged stereo systems. This amplifier contains an intelligent variable speed cooling fan that only will be activated in case of emergency.
In order to match each input to its respective source the input sensitivity can be adapted to your needs. The input stage also features a build-in 250 Hz HP-filter to optimise the system for use on horn speakers whenever you would need this. Each pair of outputs can be bridged to give you 2 x 480 watts of output power! The very intuitive front display shows what is going on with one blink of an eye. The output power is constantly under control thanks to our own made limiter that prevents annoying pumping limiter sound but yet keeps the system fully under control and you still have that dynamic sound. Ease of use, high-tech, reliability and a wide versatility has never been as cleverly combined as in this REVAMP4240T amplifier. |
The JBL Commercial CSM-21 offers fixed I/O, pre-configured architecture, full stereo or mono operation, flexible routing and control of multiple audio sources, simple front-panel configuration and control without the need for a computer, compatibility with the CSR wall controllers, compatibility with the CSPM paging microphones, and optional duplication of audio channels to another device via a Cat5 cable. The CSM-21 features two stereo music inputs with gain control and clip LEDs, and one stereo output with an active crossover and a dedicated subwoofer output. | L1400 450W-450W 4ohm (280W-280W8ohm)
COMPACT MODERN DESIGN
Compact size (2U-Rack Height) with up to 1200W per channel@2ohms
these amps save valuable rack space without compromising power output.
HIGH CURRENT TOROIDAL TRANSFORMER
A high-current toroidal transformer saves rack space
and minimizes hum and noise.
EXCELLENT SOUND QUALITY
The low T.H.D.(0.05%) and high damping factor (400 or higher)
gives excellent sound quality.
2 STAGE POWER SUPPLY
The high-power units (L1800 and L2400) have a 2-Stage Class-H design
that maximizes their performance.
EQUIPPED WITH 30Hz or 50Hz HPF
All amplifiers are equipped with high-pass filters on each channel to
help maintain sound quality, yet help protect the loudspeakers.
EXTENSIVE PROTECTION CIRCUITS
Extensive protection circuits monitor over voltage/current conditions, overheating,
output shorts, and DC voltage to improve performance and reliability.
CLIP-LIMITER CIRCUITS
Clip-limiters on each channel are provided to help prevent
distortion due to excessive signal levels.
