Subway X

Active subwoofer crossover for home cinema, hi-fi and high end

The Subway X is an active subwoofer crossover with an elegant design. In conjunction with a power amplifier and a woofer, the Subway X allows the realization of high performance subwoofer systems. Apart from mono amplifier blocks, it is also possible to use stereo or integrated amplifiers. 
Subway X offers many possibilities due to its flexibility in control and connectivity, making it the ideal choice for stereo and surround systems. Available in silver or black.

- four cinch outputs "sub out" for diverse applications like double mono or bridged mode 
- AC socket
- elegant brushed aluminium front
- toroidal transformer for minimal interference
- made in Germany

Excellent workmanship

The front plate is made from 4 mm brushed, anodised aluminium. The knobs are aluminium-coated and finished with a fine structured to offer a better grip than polished knobs.

Wide range of adjustments

The Subway X offers a wide scope of adjustmenst to optimize your subwoofer's performance to any room and personal taste:


Level Sub
Subwoofer level control.

Phase Sub
Phase control in the 0°-270° range for adjusting the acoustic delay between the subwoofer and the main speakers. The range can be extended by 180° to 180°-450°. 

Freq Sub
The subwoofer's upper crossover frequency is adjustable from 40Hz-110Hz, if the "subfilter" switch is set to "On".

Level Bass-EQ 
The amount of bass boost is adjustable up to +6dB.

Freq Bass-EQ 
The bass boost center frequency is adjustable from 20Hz-40Hz.

Subfilter
Set to "On": The Subway X employs its inbuilt subwoofer filters.
Set to "bypass": The internal subwoofer filters are bypassed. All other functions like phase control and bass boost are still active. This setting is most useful when the subwoofer is driven by a surround-decoder's subwoofer output. 


All pots offer multiple click-stops, switching contacts are gold-plated.

Connectivity

The Subway X offers signal inputs and outputs in abundance.

High Power In
Using this signal input, the Subway X can be driven by a power amplifier's loudspeaker outputs. This is useful when your setup does not offer preamplifier low level cinch outputs. The amplifier's output power should not exceed 2 x 100 W on 4 ohms. 

Line In
Cinch inputs for left and right channel. If your system only offers a mono signal, like a surround decoder does, you should use a Y-adapter (splitter) to make sure both of the Subway X's inputs are used.

Direct Out
This output is connected in parallel with line-in and can be used for daisy-chaining further equipment, like the main power amplifiers for fullrange loudspeakers, for instance. This output is still active even when the Subay X is switched off. 

Sub Out A
0°: subwoofer output for the connection to a power amplifer.
180°: phase inverted output for the connection to a power amplifier. This output should be used if you want to extend the phase adjustment to a full 180°-450°. Also, it can be used in conjunction with the 0° output to turn a stereo power amplifier into a more powerful mono bridge - i.e. "bridged mode".

Sub Out B
This output is connected in parallel with Sub Out A and can be used for further power amplifiers. This is useful if you want to realize a double mono subwoofer, for example.

AC socket
Three pole AC mains socket for 220V - 240V / 50Hz - 60Hz
