Introduction
Rockville is proud to introduce the rst commercial amplier in our new RCS series of
products. The RCS80-1 is a 60-watt, single zone, rack mountable digital hybrid amplier/
receiver. This amplier is capable of 70-volt, 100-volt, 16-ohm, 8-ohm, and 4-ohm appli-
cations. This makes it perfect for use in a restaurant/bar/café/lounge/school/conference
room or any other setting where multiple speakers are needed. With the dual mic inputs
you can use this amplier for announcements, speeches, or even for Karaoke night! The
RCS80-1 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. There are also 2-line
inputs that allow you to plug in another audio device such as an MP3 player, CD player,
TV, etc. Individual volume knobs for two microphones, MP3, and line inputs allow for full
and autonomous control of this amplier. The built-in cooling system in this amplier will
keep the components cool, making the amplier durable and reliable.
Our goal with the RCS series was to make it possible for anyone to install 70-volt sys-
tems 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 inten-
tionally 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 condent in your DIY ability when
installing our commercial system!

RCS80-1
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 amplier. For example, with this 60-watt /70-volt amplier, you can
install speakers that total close to 50 watts. It does not matter if it is 10 speakers that are
5 watts each or 20 speakers that are tapped at 2.5 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 amplier. 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 wheth-
er 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 amplier. 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.

Selecting Output Wire and Connectors
It is recommended you use high quality 16 AWG, 2 or 4 conductor, heavy gauge, CL2 or
CL3 rated, 100% Oxygen-Free Copper (OFC) speaker wire. CL2 and CL3 ratings refer to
the cable jacket’s re resistance and the voltage capacity of the wire. While both cables
have the same ame resistance capability, the CL2 cable can handle voltage spikes of up
to 150 volts while the CL3 can handle up to 300 volts. When using the 70V/100V speaker
zone output screw connectors, use terminal forks up to 10 AWG (recommended) or bare
wire. Below is a chart to help you select the appropriate size wire based on the amp to
speaker distance.
The RCS80-1 features one RCA line output. We recommend you use high quality RCA
cables such as the Rockville RNRTR10, RNRMR, or RCDR series.
Selecting Input cables
There are two ¼˝ balanced TRS mic inputs and two RCA inputs on the RCS80-1. We
recommend you use high quality ¼˝ TRS cables such as Rockville’s RCXMB, RCXFB, or
RCTR series. For recommended RCA cables see the Selecting Output Wire and Connec-
tors section above.
Rack Mounting
This unit should be on the bottom of the rack or above any equipment that does not
produce heat. Be sure to provide at least 1 RU (Rack Unit, 1.75˝) of space above and
below. Preferably, the side wall should be at least 2˝ from the sides of the amplifier and
the back of the rack should be open. This will ensure a source of cool air to all sides of
the amplier.

The RCS80-1’s 70V and 100V connections can be set up in a variety of ways. Please note
that utilizing 70/100-volt connections and 4 to 16-ohm connections simultaneously is not
recommended and will cause damage to the amplier and the speakers.

4 to 16-Ohm Speaker Output
You can connect two speakers to this terminal as long as the nal impedance does not
fall below 4 ohms. Although it is possible to connect more than two speakers to these
terminals, it is not recommended. Please consult a professional if you intend to do so as
incorrect installation could lead to irreparable damage to your amp and speakers.

Troubleshooting
PROBLEM
No sound/low
sound/distorted
sound
No power
Mic feedback or
poor sound
Buzzing sound
1. Make sure the unit is plugged in and the power switch is in the
ON position.
2. Check that the power cable is properly plugged into the wall socket.
3. Check and replace the fuse if necessary.
4. If people or equipment tend to step on and roll over or stretch
your power cable it can get damaged. Check the power cable for
damage. If the cable is damaged, discontinue using the unit until
the cable can be repaired.
1. Point mics away from any nearby speakers.
2. Make sure the microphones are on and the volume controls are
properly set.
3. Make sure the microphone cables are properly connected and
that you are using good quality TRS mic-specic cables.
Make sure you are using the proper cable. Check the require-
ments of the connected gear and the inputs on the amplier and
make sure you are using the appropriate cable. This unit’s ¼˝ mic
outputs are TRS (balanced) so you will need a TRS mic cable. For
line inputs be sure to use high quality RCA cables.
1. Check that all appropriate cables and wires are plugged in correctly.
2. Check the Master Volume settings.
3. Check the Microphone, Line input, and MP3 volume settings.
4. Check the volume settings on your input devices.
5. If using wall volume controls, be sure the volume is set properly.
6. Make sure the proper input source is selected.
7. Make sure you are using the proper type of speakers.
9. Make sure speakers are wired correctly (plus to plus, minus to
minus; not plus to minus or vice versa).
10. Make sure the speakers are wired to the correct outputs (no
4 to16-ohm speakers should be wired to the 70/100-volt direct
outputs).
11. Make sure speaker transformer taps are set properly.
12. Make sure speakers’ power ratings match the amplier’s.
