DACT Extension Shaft Kit

Extension Shafts: CT-ext1

Without the CT-ext1 extension kit, the CT2 stepped attenuators; CT3 input selector switch & the CT4 balance control have to be mounted in the front panel of the equipment enclosure. The purpose of the CT-ext1 shaft extension kit is to allow mounting of the DACT CT2 audio attenuator; CT4 balance control and / or the CT3 audio input selector switch at almost any location within the equipment enclosure. The recommended location of both attenuator and input selector switch is as near to the signal input/output sockets as possible. In this way, the signal cables may be shortened and the sonic degradation caused by the cables will be minimised.

CT-ext1 shaft extension assemble - knob and control not included.

At DACT we believe in using non-magnetic materials for audio equipment and CT-ext1 does not contain any magnetic parts. CT-ext1 consists of:

• 1 pcs Extension Shaft. When ordering please specify CT-ext1/S for a kit with a short version of the shaft (200 mm = 7.9 inch.) or CT-ext1/L for a kit with a long shaft (400 mm = 15.7 inch.). Shaft material: Plastic.
• 2 pcs Connection Link. Material: Brass. The connection link includes 4 pcs M3 stainless steel screws.
• 1 pcs Front Panel Bearing Bush. Material: Brass. Includes 1 pcs M10 stainless steel nut.

Assembly Instructions

1. Mounting the Front Panel Bearing Bush.
To mount the bush in the front panel requires a hole in the front panel of at least 10 mm (0.395 inch.). Preferably, the hole should not be larger than 13 mm (0.512 inch.). Fasten the bush using the supplied M10 stainless steel nut.

2. Mounting the Connection Link.
Please observe that the mounting holes in the two ends of the link are not of equal size. The smaller hole (6.05 mm = 0.238 inch.) is for fitting the link to the shaft of CT2, CT3 or CT4. The other end (hole diameter 6.6 mm = 0.260 inch.) is for fitting the aluminium extension shaft. Make sure to tighten all four screws properly.

3. Fitting the Extension Shaft.
If the extension shaft is longer than required, it may be cut to the right length accordingly. PLEASE MAKE SURE always to cut the end of the shaft with the largest diameter. This end is to be fitted into the Connection Link, whose hole diameter will accept the diameter of the non-machined end of the shaft. Please observe that the shaft is designed to be used with a knob that has a 6.0 mm hole (and not with a knob that has a 1/4" hole).
