Superbooth17 – Arrel Audio

Arrel ER-150

After releasing the ER-100 Summing Mixer, the ER-110 Stereo Parametric Equalizer and the ER-130 VC Mid-Side Unit, Arrel Audio developed a high-end power supply for modular systems. Two versions will be available, each is composed of a module plus bus boards. Their technical specifications are identical. Both come equipped with short circuit as well as overheating protection and deliver up to 3 A at +12 V, 1 A at -12 V and 1 A at +5 V. The noise floor is very low.

What separates the two systems is the module design. While the ER-160 is only 4 HP wide and comes with just a power connector plus LEDs to check for proper operation, the 10 HP wide ER-150 features a big VU meter that shows the current drawn by the modular system. – A very nice idea. Additionally, the ER-150 has an output for feeding power to a second rack.

Furthermore, Arrel Audio designed an expander for the ER-100 Summing Mixer, the ER-140 Summute. It is composed of two sections, each featuring four channels with input, mute switch and output. Additionally, there is a mix output plus gain potentiometer and saturation LED per group.
