The 18S features a closed box acoustic system and incorporates dual opposed 24cm drivers to minimise mechanical vibration. Connection facilities include balanced XLR and unbalanced stereo inputs with output sockets provided to enable the connection of active monitors, a power amplifier for passive monitors, or a second subwoofer. 10 The 18S incorporates low-pass filter presets configured to match a range of Dynaudio monitor models, three bands of parametric equalisation, and an adjustable low pass filter that can be configured for use with monitors from alternative manufacturers. 18S configuration and control is accomplished through a rear panel mounted display combined with a rotary controller. 11 Unpacking 1 Unpacking 12 2 3 1.

However, best results will most likely be obtained if your 18S is placed between the left and right monitors or in the vicinity of one of them. If this is not practical, a subwoofer position to the side of the left or right monitor, or against a side wall can also provide good results. Placing a subwoofer close to or behind or the listening position, even in multichannel surround sound installations, generally results in inferior performance, especially in terms of stereo imaging. Note Two subwoofers used in a single installation can improve performance by maintaining low frequency stereo separation and effectively averaging the effects of low frequency room resonances. 16 Moving the subwoofer closer to walls and corners will generally increase the amount of bass. Although the extra amount of bass can be compensated for by reducing the volume level of the subwoofer relative to the rest of the system, this can result in uneven bass response at the listening position. Experiment with the position of your 18S to find one which yields the best compromise between convenience, volume and even bass response. Note Every studio room will have “room-modes”, where at specific locations and frequencies, the bass may be under or overemphasised. This effect is likely to be stronger in square and rectangular shaped rooms. Experimenting with the position of the subwoofer is likely to reap benefits in terms of minimising room modes. The 18S incorporates signal processing that can compensate for the time delay and volume level differences between the subwoofer and monitors resulting from their relative positions with respect to the listening position. Once you have positioned your subwoofer, measure the distances as illustrated. The measured distances should then be specified at the appropriate locations in the subwoofer configuration menu. The configuration menu is described in Section 3 of this manual. Left monitor distance Right monitor distance Listening position The 18S signal processing is able to compensate for a maximum of 5.35m difference between subwoofer and monitor distances to the listening position. 17 Installation Mains and signal connections Subwoofer connections The 18S is fitted on its rear face with a connection and control panel carrying mains, signal and connection sockets. The panel is illustrated in Diagram 3 and its connection facilities are described in the following paragraphs. 2. B alanced XLR input sockets (left and right). If your monitoring hardware provides balanced outputs connect them to these sockets using high quality balanced XLR audio cables. 1. M ains power socket. Connect the subwoofer to a mains power supply using the cable supplied. If multiple cables are supplied with your subwoofer, use the one appropriate for your territory. 3. B alanced XLR output sockets (left and right). The XLR output sockets are intended for the connection of active left and right monitors, a power amplifier driving passive monitors, or a second subwoofer. Note Do not switch on your subwoofer until all other connections have been made. Note The 18S distance compensation signal processing can only function correctly if the monitors are driven via the subwoofer outputs. 4. U nbalanced phono input sockets (left and right). If your monitoring hardware provides unbalanced phono outputs connect them to these sockets using high quality phono audio cables. Note If your audio source provides only a mono subwoofer output it can be connected to either 18S phono input. In this case however the main speakers must be driven from the audio source and not via the 18S outputs. 5. U nbalanced phono output sockets (left and right). The phono output sockets are intended for the connection of active left and right monitors, a power amplifier driving passive monitors, or a second subwoofer. 6. T rigger input. The trigger input enables wired remote control of subwoofer standby and operational modes in automated systems. Your Dynaudio retailer or installer will be able to provide more information on the use of the 18S in automation systems. Service Auto ON/OFF Trigger in Note The USB socket present on the 18S connection panel is intended for fault diagnosis and firmware update only. It cannot be used for audio connection or playback. Contact your Dynaudio retailer or Dynaudio directly for more information of firmware updates.

The 18S must be configured appropriately for the monitoring system and main speakers with which it is to be used. This is achieved via the rotary controller, display and menu based interface on the rear panel. Turn the rotary controller to select configuration parameters and press the control to select options. Note If multiple subwoofers are employed they should be configured identically. 23 Control and configuration Subwoofer controls The 18S configuration menu parameters and their options are described in the following paragraphs: • Input sensitivity: Adjusts the input sensitivity to match the output level of your audio interface or console. Initially select the 0dB option. Only adjust the input sensitivity if the subwoofer volume adjustment doesn’t provide a suitable range. • Volume: Set to match the volume of your main speakers so that bass at your main listening position is neither too prominent or too quiet. Note Setting the subwoofer volume is important in terms of both overall system balance and the demands of different types of programme material. 24 • Presets: The 18S incorporates low pass filter presets to match a range of Dynaudio monitor models. If your 18S is to be used in a system with one of the Dynaudio models listed, select it to configure the 18S low pass filter appropriately. If your subwoofer is to be used for the LFE channel in a multi-channel system, select the filter Bypass option. • Parametric EQ: Provides three bands of low frequency parametric equalisation. Each band offers frequency, gain and Q parameters. Parametric is best used in combination with low frequency room acoustic analysis to identify frequency response anomalies. The equalisation is set to “flat” by default. • Auto standby: Select to specify the delay time before the subwoofer will switch to Standby mode when unused. The auto standby feature can also be switched off. • Line Wake-up: Select to enable or disable trigger input switch on. • L eft main speaker distance: Select to specify the distance in metres of the left channel monitor from the listening position. • R ight main speaker distance: Select to specify the distance in metres of the right channel monitor from the listening position. • S ub speaker distance: Select to specify the distance in metres of the subwoofer from the listening position. • Status: Select to display the subwoofer operational status. • Factory Reset: Select to return your 18S to its default settings. The rear panel Auto ON/OFF switch will engage or defeat automatic switch on and off in response to the presence or absence of an input signal. Rotary controller: Rotate to select. Press to confirm. Note If your Dynaudio monitor model is not listed among the 18S presets, or your 18S is to be used with monitors from an alternative manufacturer, select a low pass filter frequency closest to the monitor’s specified -6dB low frequency cut-off. 25 In use In use Once installed and configured, your 18S should require little attention other than perhaps occasional volume control adjustment to suit different types of programme material. Cleaning your subwoofer Brush the cabinet surfaces with a clean lint-free cloth. Do not use a vacuum cleaner. If you wish to use a cleaning agent, apply it to the cleaning cloth and not directly to the subwoofer. Test a small area first, as some cleaning products may damage some of the surfaces. 26 Support Should you require help or advice there are a variety of support options for Dynaudio products.
