RADIAL HEADBONE VT AMP SWITCHER FOR - Part Number 000144
Headbone VT Switch 2 heads using one speaker cabinet Slingshot� remote control with any footswitch Digital micro-controlled relays for failsafe switching Choice of direct or buffered input Models for tube amps (VT), solid-state(SS) or both (TS) The Radial Headbone is an advanced amplifier switching device that allows two different guitar amp heads to be used with a single speaker cabinet. With the Headbone, one head could be used for rhythm while a second head could be used for soloing. With 100% discreet Class-A circuitry and choice of either buffered or un-buffered inputs, the Headbone will be of particular interest for players that demand the utmost in tonal performance. The Headbone's internal switching comprises a sequence of relays, photocells, and load resistors, all of which are controlled via a digitally programmed chip. Hit the footswitch and the Headbone toggles the guitar signal from one amp to the other, disconnects the speaker and diverts the signal to a load resister, reconnects the speaker to the second head and turns on the guitar, all in quick succession. The Headbone features SafeMode� whereby even when power is disconnected; the Headbone will automatically default to 'head-1 to cabinet' status, ensuring a constant load on the amplifier. Headbone comes equipped with Slingshot�, an easy-to-use switching system that uses any standard footswitch to toggle the Headbone's status remotely, from wherever the footswitch is located. Slingshot lets you keep the amp-to-speaker cables short and efficient and opens up new switching possibilities too. The Headbone is available in 3 models: The VT for two valve/tube heads, the SS for two solid-state heads and the TS for tube to solid-state amp head switching. Headbone � another Radial 'power tool' for serious guitarists. Features & Specifications The Radial Headbone combines simplicity with functionality. Hook-up was designed to be intuitive for all users, be they neophyte or experienced technician. Although most will be able to connect and play through the unit immediately, we recommend a thorough reading of the user guide first for best results and safety. In use, the Cabbone is a model of logical design and offers the professional guitarist the ultimate in creative options on stage through smooth and noise free amplifier switching. An on-board footswitch toggles between amp heads and large LED indicators monitors the current signal path. Tonebone's versatile Slingshot� system allows remote controlled switching between heads from any stage position (eg.: a pedalboard) using just regular �" to �" guitar cables. Specifications Circuit type: Proprietary electro-mechanical Audio Signal Path: Class-A - 100% discrete componentry Input impedance: 100 kOhms (direct input) 10 kOhms (bufferd input) Switching type : Programmed PIC controlled relay Relay type and capacity: Silver plated contacts - 10 million cycles 100 Watts RMS rated Switching time: 11.2 milliseconds Outputs: Speaker out Slingshot� implimentation Slingshot� remote switching input Footswitch: High-cycle heavy-duty Amp-1 / Amp-2 toggle with status LED's LED indicators: Large 3mm OD ultra-bright LED's Construction: 14 gauge steel, baked enamel finish Size: 6.85 x 4.5 x 2.12" (175 x 108 x 54mm) Weight: 2.2lb (1.kg) Maximum Power Ratings To switch the speakers inside the Headbone, a relay is used that is rated for 100 Watts (MUSICAL PROGRAM). This 'general' specifications does offer some leeway as detailed below. Please consult your local Tonebone dealer to ensure your system is configured to meet the following specifications: 100 Watt into 4 Ohms = 5.00 Amp RMS 100 Watt into 8 Ohms = 3.54 Amp RMS 100 Watt into 16 Ohms = 2.50 Amp RMS 150 Watt into 4 Ohms = 6.12 Amp RMS (safe) 150 Watt into 8 Ohms = 4.33 Amp RMS 150 Watt into 16 Ohms = 3.06 Amp RMS 200 Watt into 4 Ohms = 7.08 Amp RMS (not reccomended) 200 Watt into 8 Ohms = 5.00 Amp RMS 200 Watt into 16 Ohms = 3.54 Amp RMS Safety Note: Although the headbone relay is rated to withstand a 10 Ampere load, due to peak power surges and the total power caused by heavily distorted sound, we recommend a 40% minimum safety margin for a maximum 6 Amps of current be applied. NOTE: THIS UNIT SHIPS WITH A 115 VAC 60HZ POWER SUPPLY FOR USE IN NORTH AMERICA AS WELL AS ANY OTHER COUNTRY WITH 115-120 VOLT SERVICE.
