DS10: Controls, Inputs & Outputs

Introduction

This article explains the main controls, inputs, and outputs on the Rockville DS10 amplifier. It is written in a simple, easy-to-follow way, even if you have no technical experience. By the end, you will know what each knob, switch, input, and output does and when to use it.

Requirements

• Rockville DS10 amplifier
• A basic understanding of which devices you plan to connect (for example, speakers and a mixer)

Step-by-Step Guide

1. Identify the front panel controls and indicators

1. Locate the two volume controls on the front of the DS10:
   • Channel 1 volume
   • Channel 2 volume
2. Check the volume indicator for each channel. This helps you see the output level for each channel.
3. Look for the Limit indicator:
   • This may turn on if the amplifier is being pushed too loud.
4. Look for the Fault indicator:
   • This may turn on if something is wrong with the amplifier.

2. Identify the rear panel inputs and outputs

XLR Inputs (Audio Inputs)

1. On the back of the amplifier, locate the XLR inputs:
   • Channel 1 XLR input
   • Channel 2 XLR input
2. These inputs allow you to connect audio from devices such as:
   • A mixer
   • Another power amplifier (depending on your system)

SpeakON Outputs (Speaker Outputs)

1. Locate the SpeakON outputs:
   • Channel 1 SpeakON output
   • Channel 2 SpeakON output
2. These outputs are used to connect your speakers to the amplifier.

Positive and Negative Terminals (Alternate Speaker Connection)

1. Locate the positive (+) and negative (-) speaker terminals on the back.
2. These terminals allow another way to connect speakers besides SpeakON.
3. This is especially useful when using the bridge feature to power one speaker, because bridge mode commonly uses the positive terminals.

3. Understand the amplifier mode switch (Stereo, Parallel, Bridge)

1. Find the mode switch on the back of the DS10.
2. The amplifier has three modes:

Stereo Mode

• Used for a standard left and right setup.
• Channel 1 input goes to Channel 1 output (for example, a left speaker).
• Channel 2 input goes to Channel 2 output (for example, a right speaker).

Parallel Mode

• Acts like a mono-style input mode.
• Anything plugged into Channel 1 input will come out of both Channel 1 and Channel 2 outputs.

Bridge Mode

• Combines the power of both channels to power one speaker.
• This mode is used when you need to drive a single speaker with higher power than one channel alone.

4. Understand the crossover switch (frequency range control)

1. Find the crossover switch on the back of the amplifier.
2. This switch determines which frequencies the amplifier sends to your speakers.

Full Range

• Sends the full range of frequencies (lows, mids, and highs).

Low Pass

• Sends only the low frequencies.
• Commonly used when powering subwoofers.

High Pass

• Sends only the higher frequencies.
• Commonly used when powering speakers intended for mids and highs.

Troubleshooting and FAQs

The Limit light turns on. What does that mean?

• The amplifier may be getting too loud or being pushed too hard.
• Try lowering:
  • The channel volume controls on the amplifier, and/or
  • The output level from your audio source (for example, your mixer)

The Fault light turns on. What should I do?

• The amplifier is indicating that something is wrong.
• Turn the system down and re-check your connections.
• If the issue continues, stop using the amplifier until the cause is identified.

Which mode should I use: Stereo, Parallel, or Bridge?

• Stereo: best for standard left/right speaker setups.
• Parallel: best when you want one input signal coming out of both channels.
• Bridge: best when you need to combine both channels to power one speaker.

Which crossover setting should I use?

• Full Range: for general use when you want all frequencies.
• Low Pass: when you only want bass frequencies.
• High Pass: when you only want higher frequencies.

Conclusion

You now know what the DS10 front panel controls and indicators do, how the XLR inputs and speaker outputs work, what the positive and negative terminals are used for, and how to choose the correct mode and crossover settings.
