متوسط

This is a very nice tool for me to compare my speakers I can connect 4 set of speakers, and play any combination and also compare two different Amplifiers and play any set of the four set of speakers with Amplifier A or B and very easy to connect your speakers

Estoy muy satisfecho con este equipo, puedo distribuir muy bien mis bocinas, pero sobre todo, nivelar el volumen de cada par.

Compré uno para mi casa y a menos de 5 minutos que quería comprar otro (para ponerlo en mi oficina) el precio ya había incrementado $700 mas, lástima de vendedor. Veré si funciona bien el único que compré!

I have the PSLSW4 4-zone speaker controller but they also make a 6-zone controller. I have this mounted on my covered patio and it is fed from a Bluesound Node audio streamer and a Fosi Audio TB10D amplifier. My Fosi amplifier puts out about 100watts a channel at 8ohms with the upgraded power supply. The Pyle speaker selector will accommodate 2 separate input devices. A or B so you could have different sounds playing in different zones. I am only using zone A. The preferred zone is selected with a switch adjacent to each volume control. It is either A or B but to turn off individual zones to be OFF, you must rotate the volume knob to OFF. The volume knob click into each volume level - it is not a smooth rotating dial but it works fine. There is no crackle or pop when moving the volume control knob. the back of the unit has plenty of room to connect the speaker wire either directly or using a banana plug. There is no balance control for right to left channel adjustments. I am feeding 2 sets of patio speakers and 2 sets of rock speakers out in the yard and all are fed with 14awg wire. All my speakers are 8ohms. My speakers sound fine and they get loud enough for adequate sound. This is an outdoor background sound system and it won't sound like a rock concert in your backyard. Make sure your amplifier is stable down to 2ohms if you will be playing all 4 speakers simultaneously. If only one speaker is ON it will see an 8ohm load on your amplifier. If any 2 speakers are ON, your amplifier will see a 4ohm load. If any 3 speakers are ON your amplifier will see a 3.1ohm load. The Fosi class D amplifier I am using is rated from 2 to 8ohms. This switch can handle up to 100watts RMS input with 18watts RMS output per speaker output. This switch is passive so it doesn't require any power source.

This passive speaker select/volume controller fit exactly what I needed. I have a multi input amplified mixer that directly feeds a set of monitor speakers for my drums, and a Bose L1B2 that I use vocals, and Bass fed through the headphone jack during band practice. I kept having to disconnect my speaker cables during band practice because The mixer would not allow the speakers to be reduced in volume and still generate enough output for the Bose. This Pyle unit has 4 speaker controls which is overkill for me, but the volume control works amazing, and if needed a simple button disconnects all speakers. A little bigger than I needed space wise, but works amazing.
