Remote Contr ol
The Velodyne Digital Drive infrared remote control allows you to set up, adjust, and reset your SMS-1 when connected to a television or a video monitor. You will also use your remote to activate preset listening values, set the SMS-1’s volume up or down, mute the SMS-1, or set a night operational mode.
Take care not to lose or misplace your remote control as adjustments to the SMS-1 (with the exception of volume control) can only be done using the remote.

Installation – Quick Start
To quickly set up and take advantage of the auto-EQ feature in your new Digital Drive SMS-1, perform the following steps:
1.Unpack the SMS-1 and connect the power cable.
2.Connect an LFE input cable from your receiver/processor to the input jack. For other hookup options, see step 2 on page 9.
3.Connect a high quality line level cable from one of the LFE out jacks to your subwoofer.
4.Disable your subwoofer’s crossover if possible, and set its volume to one-quarter up to one-half setting.
5.Power up the unit and ensure that it is receiving and processing signal from your receiver (i.e. your subwoofer is playing bass).
6.Connect the microphone (found in the accessory kit) to the XLR mic input jack on the front or rear panel of the SMS-1 and place the mic in your favorite listening position.
7.Press 3-2-1 on the remote.
8.The subwoofer should emit 25 “sweep” tones then restart and play normally. NOTE: If you have the video connected you will see the sweep screen with Self-EQ mode indicated. This screen will show the EQ adjustments as they happen.
9.Adjust the SMS-1’s volume and your subwoofer’s volume to taste.
10.Enjoy your room-equalized sub!

Installation– Step-By-Step
To ensure a quick and flawless installation of your Velodyne Digital Drive SMS-1, follow these setup instructions.
SMS - 1 Cable Connections
Make all necessary cable connections between the applicable SMS-1 connector port and your particular home electronics equipment in the following order:
1.Insert the detachable power supply into the power interface port on the rear panel of your SMS-1. Plug the male end of the cord into a convenient wall outlet.
2.Provide signal to your SMS-1 through one or more of the following connections (refer to your receiver/processor owner’s manual for available inputs to the SMS-1):
a.LFE INPUT (RCA, the RED jack at location 17 on Figure 1) – This is the most common input cable connection. Make a connection between this input and the LFE output of your receiver or processor; OR
b.LFE INPUT (XLR, location 7 on Figure 1) – Make a connection between this input and the balanced LFE outputs of your receiver or processor; OR
c.INPUT, LEFT and RIGHT (location 17 on Figure 2)– Make a connection between these inputs and the stereo outputs of your receiver or processor; OR
d.SPEAKER-LEVEL INPUT (location 18 on Figure 2) - Make a connection between these inputs and the left and right speaker connections on your receiver or processor. Make this connection by inserting speaker wire into the correct terminals of the terminal block.
3.Establish the return line-level connection (optional). Connect to a pre-amplifier’s main outputs and return them to your amplifier inputs. When installed in this fashion, your satellite speakers will be crossed over at 80Hz, which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-amplified system, gaining improved power and headroom for your system.
NOTE: To bypass the 80Hz crossover described in step 3, use the THRU output jacks instead of the OUTPUT jacks.
A wor d about SMS - 1 outputs
The Velodyne SMS-1 is designed to operate using the full range audio signal for input when using the digital built-in crossover. Most processors/receivers have a “subwoofer out” or LFE jack that is internally filtered and designed to be used with a conventional amplifier and speaker. In some rare cases, combining both an external crossover and the one internal to the SMS-1 may result in low output and increased noise. In these installations you may need to bypass the internal crossover in either the processor or Velodyne SMS-1. In some installations, simply setting one crossover to a higher frequency (such as 120Hz) will restore maximum performance. To bypass the SMS-1’s internal crossover when the unit is being fed a low pass signal from another crossover, refer to the SETUP instructions at step 14, below.
Note: If not using an |
