Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better!

Getting Started

We recommend that you:

• Unpack the equipment carefully and save the original box and packaging materials for possible future shipment.
• Review the contents of this user manual.

 Go to www.kramerav.com/downloads/KRT-4 to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).

Achieving the Best Performance

• Use only good quality connection cables (we recommend Kramer high performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables).
• Do not secure the cables in tight bundles or roll the slack into tight coils.
• Avoid interference from neighboring electrical appliances that may adversely influence signal quality.
• Position your Kramer KRT-4 away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

• This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.
• There are no operator serviceable parts inside the unit.

Recycling Kramer Products

The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility. For details of Kramer’s recycling arrangements in your particular country go to our recycling pages at www.kramerav.com/support/recycling.

Overview

KRT-4 is a cable retractor, with a gentle retraction mechanism, that is designed for installing in a meeting room, classroom or other AV site. You can furniture-mount KRT-4 or install one or more KRT-4 units in conjunction with a Kramer TBUS unit, such as TBUS 1AXL, TBUS-10XL, UTBUS-1XL, UTBUS-2XL and more. KRT-4 extends a variety of common AV connector types and is easy to install and use.

KRT-4 provides user-friendly installation and operation:

• Convenient and easy to install in any TBUS.
• Intuitive Use – Pull and stop or pull and retract.
• Cable slowly retracts for safe use.
• Available Cable Types:
  • HDMI™.
  • VGA.
  • Audio (3.5mm).
  • LAN.
  • USB-3.0.
  • DisplayPort.
  • HDMI extender (KRT-4-3H2, see KRT-4-3H2 Features on page 4).

 Refer to www.kramerav.com/product/KRT-4 for the updated configuration list.

• Maximum Cable Extension – Up to 1.8m (6ft).
• Horizontal Mount – Easily mounts, independently, under a table or shelf.
• TBUS Compatibility – Retractable cable mounts directly into the TBUS insert opening via a cable pass-through opening.
• Installation – KRT-4 is sturdy, cost-effective, and easy to install.

 The HDMI cable version is used throughout this manual as an example. The same applies to retractors with other cable types.

Typical Applications

The KRT-4 is ideal for:

• Boardrooms and conference rooms.
• Training rooms.
• Hotel lobbies.
• Cafes and restaurants.

KRT-4-3H2 Features

The KRT-4-3H2 retractor side is a 4K HDR equalizer and line driver for HDMI and HDCP 2.2 signals that extends the range when using long HDMI cables.

Figure 2: KRT-4-3H2 – Extender Side

KRT-4-3H2 features:

• A range of 10m to input, 10m from output, total 20m (65ft) at 4K@60Hz (4:4:4); 25m to input, 15m from output, total 40m (130ft) at 4K@60Hz (4:2:0); 30m to input, 15m from output, total 45m (150ft) at 1080p60.
• HDTV compatibility.
• HDCP 2.2 support.
• HDMI Support – HDR10, ARC, CEC, deep color, x.v.Color™, Lip Sync, 7.1 PCM, Dolby TrueHD, Dolby atmos DTS–HD, 2K, 4K, and 3D Dolby Vision as specified in HDMI 2.0.
• Optional external power supply via micro USB port (micro USB cable not included)

 In some installations, external power may improve the overall KRT-3H2 performance.

Installing KRT-4

KRT-4 can be installed in the following ways:

• Attaching KRT-4 to the Underside of a Table.
• Attaching KRT-4 to a TBUS.

Attaching KRT-4 to the Underside of a Table

You can mount KRT-4 to the underside surface of a table and use it as a standalone device.

To attach KRT-4 under a table:

1. Place KRT-4 under the table in the desired location. Make sure that the retracting cable faces the edge of the table.
2. Pass the 3 M4x50 Philips screws through the table screw openings and tighten them to fix the retractor under the table.

Figure 3: Attaching KRT-4 to a Table

Attaching KRT-4 to a TBUS

You can attach one or more KRT-4 units to the enclosure of any modular Kramer TBUS with pass-through inserts that are installed inside a table. The KRT-4 units can usually be attached to the front and rear sides of the enclosure, as the left and right sides are fitted with clamps. Alternatively, the clamps can be installed on the front and rear sides to enable attaching KRT-4 to the left and right sides of the TBUS enclosure.

For TBUS models with a sliding lid (for example, TBUS-10xl), you can only use the front side of the enclosure to mount the KRT-4 units.

Attaching a Single KRT-4 Unit

To Attach the KRT-4 to a TBUS unit:

1. Slide the KRT-4 onto one of the sides of the TBUS enclosure. Make sure to position the fixed cable downwards and the retractor cable upwards.
   
   Figure 4: Sliding KRT-4 onto the TBUS Enclosure

2. Use the wing-head thumb screw to fix the KRT-4 firmly in place.
   
   Figure 5: Tightening KRT-4 to the TBUS Enclosure

3. Attach the WCP-(KRT) insert in the following way:
   a. Insert the cable through the bushing opening.
   b. Insert the cable with bushing through the insert opening.
   c. Push the bushing into the insert opening.
   
   d. Use the two M3x5 screws to attach the insert to the TBUS opening.

The KRT-4 is now firmly fixed in place.

Figure 6: KRT-4 Attached to TBUS – Under Table

You can attach several KRT-4 units to a Kramer TBUS:

• For TBUS units with a sliding cover (for example, the Kramer TBUS-10xl), attach the KRT-4 units side-by-side to the front side of the TBUS enclosure **(Figure 7):

Figure 7:** Attaching Several KRT-4 Units to TBUS with Sliding Cover

• For TBUS units with a regular cover (for example, the Kramer TBUS-1Axl), attach the KRT-4 units side-by-side to the front and rear side of the TBUS enclosure (Figure 8).

 To maximize the number of KRT-4 units that can be attached to TBUS-1AXL, TBUS-1-KWC or TBUS-1N, use an inner frame that does not include single or dual power sockets or alternatively, install T-2INSERT/T-4INSERT in the single/dual power socket opening.
