Intusonic INTUFORCE 4SDL160 4 x 150W Power Amplifier, 4-8 Ohms
The INTUFORCE 4SDL160 is a versatile 4x150W amplifier, boasting incredible flexibility on the output & input stage. This makes it suitable in just about any environment.
The Intusound INTUFORCE 4SDL160 4x150W amplifier is a perfect option for people looking to install a feature-rich, high-quality audio system in their business.
This particular amplifier is suited for gyms, bars, restaurants & retail stores.
Input Control
The 4SDL160 features four balanced XLR inputs to connect your audio sources. Each input has a 1.4" Jack 'link', which can feed the signal to another amplifier if more power is required.
On the front of the amplifier are easy-access volume controls for each channel, as well as a recessed volume control on the rear of the amplifier. By default, the front panel volume controls are active, however, they can be switched off (per channel).
This is great in customer-facing, or staff-heavy environments like a restaurant or cafe, as it ensures the volume cannot be adjusted on the fly without permission, and it will ensure it never goes over your desired level.
Each input channel also has a selectable 100Hz high pass filter to cut out any unwanted muddy bass tones.
Operation Modes
The 4SDL160 can be run in a number of ways to suit the desired purpose. It can be run in 4-zone, 2-zone, 1-zone or 2.1.
In 4-zone mode, each input is assigned to a separate output:
- In A - Ch 1 / In B - Ch 2 / In C - Ch 3 / In D - Ch 4
In 2-zone mode, input A is assigned to output 1 & 2, and input B is assaigned to output 3 & 4:
- In A - Ch 1 & 4 / In B - Ch 2 & 3
In 1-zone mode, input A is assigned to every output:
- In A - Ch 1, 2, 3 & 4
In 2.1 mode, Input A & B are assigned to outputs 1 & 2 respectively, for use with satellite speakers. The input signal from A & B is also mono summed and sent to outputs 3 & 4 as a mono signal, with a low pass filter applied for use with a subwoofer.
Inputs C & D are unused.
- In A - Ch 1 / In B - Ch 2 / In A & B (mono summed) - Ch 3 & 4
2.1 Mode Controls
2.1 Mode has a few dedicated controls which are separate from the other operation modes. There is a dedicated volume control for outputs 1 & 2 (satellite speakers), and 3 & 4 (sub).
There is also a selectable crossover frequency between the two outputs.
Amplification
Each output is 150W RMS at 4 Ohm, however, outputs 3 & 4 can be bridged. The amplification is Class-D ensuring efficient, cool & quiet operation.
Class-D is also great at producing a clean and punchy bass signal, making this a great choice in louder environments such as gyms or bars.
