Description:

Introducing the Rockville PRE-70V 70V 8 zone Pre-amp mixer with Bluetooth and optical. This is the perfect solution for commercial audio applications. With 8 mono or 4 stereo zones with independent volume controls and lots of source playback options this will be your go-to 70V product for your next installation. This mixer/pre-amp is designed to work seamlessly with any 70V power amplifier up to 1,000 watts RMS in total (500 x 2 or 1000 x 1).

There are 2 mic inputs with echo control (one with talk over function). You also get 1 RCA line input, 1 optical input, and an RCA line output.

Each zone can have an unlimited amount of speakers wired in parallel as long as you do not exceed the power of the amplifier that is plugged into this.

This model also includes a chime button so you can create a chime sound before making announcements.

The PRE-70V series features Bluetooth audio streaming so you can play your favorite music or access a playlist right from your phone! This amp also features both USB and SD inputs allowing you to play audio stored on a USB thumb drive or SD Card.

We also have convenient euro-block speaker terminals that make it super easy to install the wires even if the receiver is hidden in a corner. The terminals are detachable and once you connect your speaker wire to the terminal it just clicks into the receiver.

Our goal with the PRE-70V is to make it possible for anyone to install 70 volt systems on their own without spending thousands of dollars on a contractor. This model makes it a breeze to connect many speakers and multiple external sources. We intentionally use common plugs like RCA and ¼" on our model to make this more universal and user friendly. With our unique design you can feel confident in your DIY ability when installing our commercial system!

Wiring is simple:

1.Connect bare wire from the PRE-70V output and plug it to the input of your amplifier. 
2.Connect bare wire from the output of your power amplifier back to the 70V input on the PRE-70V
3.Connect the 70V speakers to the speaker output on the PRE-70V

What is 70 volt ?

70 volt systems are the number one choice for any application where you want to install multiple speakers. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up speakers with the amplifier. If you were to use this PRE-70V with a 250 watt 70V power amplifier then you can install speakers that total close to 250 watts. It does not matter if it is 10 speakers that are 20 watts each or 25 speakers that are tapped at 7.5 watts each. You always want your 70 volt amp to have at least 15 or 20% more power than the combined watts your speakers are tapped at. When we say the word tap, what we are referring to are the selectors that many speakers in 70 volt have on them. For example, some speakers might have selectable options of 1.5w, 3w, 5w, 10w. What this does is limit how many watts the built-in transformer on the speaker will allow the speaker to get from the amplifier. What this allows for is full customization of your sound for your space. In a restaurant for example you can tap your dining room speakers at 5 watts, the speakers by the bar area at 10 watts, the ones in the hallway at 3 watts and the speakers in the bathrooms at 1.5 watts. Another great feature with 70 volt is you can mix and match any 70 volt speakers whether they are ceiling speakers, wall mounted speakers, subwoofers, etc.

70 volt systems allow you to run very long lines of speaker wire without signal loss. This makes it ideal when running long speaker leads.
The wiring is simple. You just wire all the positive terminals of the speakers to the positive 70 volt terminals of the amplifier. The negative terminals on the speaker simply get wired to the negative terminals on the amp. You do not have to worry about impedance. The power is constant.

All About Your CH-MIC70:

How To Set up Your CH-MIC70:

What's In The Box:

• Microphone
• 30 Foot ¼" to ¼" cable

Description:

The CH-MIC70 is a push to talk gooseneck condenser paging microphone with built in chimes designed for commercial applications. It has a built in mic preamp to ensure it gets a strong and clear signal without distortion. It also does not require 48V phantom power because it has the pre-amp built in! Simply plug this into either a line level or mic level input of your mixer or receiver and you are good to go.

This mic was designed by Rockville and works in the following way:
1. When you want to talk into the mic and make an announcement it will make a chime in sound and then you can make your announcement.
2. When you are done with your announcement you hit the mic out button and it will make a chime out sound and the mic will be muted.

We also added a chime volume control that allows you to raise or lower the volume of the chime. You can turn the chime off by lowering the chime volume to 0.

This mic has a great frequency range and great sound quality. Most people use it for announcements and speeches but you can even sing into the mic it will sound great.

This mic has a flexible gooseneck making it perfect for conference rooms, churches, schools, restaurants, and other commercial applications.

Lastly, the included pop filter enhances the signal by reducing the amplitude of the plosives in the speech making the output clean and balanced.
