Kenwood TS-480SAT, TS-480HX Accessory Connections, TX/ RX Unit, Remote Control Panel

ACCESSORY CONNECTIONS

TX/ RX UNIT

■Microphone (MIC)

Connect a microphone having an impedance between 250 and 600 Ω. As for the supplied microphone, fully insert the modular connector into the MIC jack until the locking tab clicks. You can still utilize 8-pin metal type plug microphones, such as MC-43S, MC-47, and MC-60A with the optional MJ-88 adaptor (optional) if necessary. However, do not use the MC-44, MC-44DM, MC-45, MC-45E, MC-45DM, MC-45DME, or MC-53DM condensor-type microphones.

■External Speaker (EXT.SP)

On the front panel of the TX/ RX unit, there is an external speaker jack. If an external speaker is connected to EXT.SP jack, the built-in speaker on the back of the Remote Control panel will mute. Use only external speakers with an impedance of 4 to 8 Ω (8 Ω nominal). The jacks accept only

3.5 mm (1/8") diameter, 2-conductor (mono) plugs.

¥The ÒÓ projection indicates the external speaker jack.

Note: Do not connect headphones to this jack. The high audio output of this jack could damage your hearing.

■Keys for CW (PADDLE and KEY)

For CW operation using the internal electronic keyer, connect a keyer paddle to the PADDLE jack. For CW operation without using the internal electronic keyer, connect a straight key, semi-automatic key (bug), electronic keyer, or the CW keying output from a Multi-mode Communications Processor (MCP) to the KEY jack. The PADDLE and KEY jacks mate with a 3.5 mm (1/8") 3-conductor plug and a 3.5 mm (1/8") 2-conductor plug respectively. External electronic keyers or MCPs must have a positive keying output to be compatible with this transceiver. Use a shielded cable between the key and the transceiver.

¥The Ò¥Ó projection indicates the key jack and the Ò¥¥Ó projection indicates the paddle jack.

Note: Due to the functionality of the internal electronic keyer, you may find it unnecessary to connect both a paddle and another type of keyer unless you want to use a PC-based keyer for CW. Refer to the “ELECTRONIC KEYER” section {page 39} to become familiar with the internal keyer.

■Headphones (PHONES)

Connect monaural or stereo headphones having a 4 to 32 Ω impedance. This jack accepts a

3.5mm (1/8") diameter, 2-conductor (mono) or 3-conductor (stereo) plug. After connecting the headphones, you will hear no sound from the internal (or optional external) speaker.
