参数话筒均衡器

Parametric Microphone Equalizer
本章要点：FTX-1 内置独特的三段参数话筒均衡器（Three-Band Parametric Microphone Equalizer），可对语音波形的低、中、高三个频段分别独立调节中心频率、增益和带宽（Q）。本章说明均衡器的启用方法、Speech Processor 关闭与开启两套独立参数的调整流程，并逐项列出全部菜单项的可调范围与默认值。

26.1 功能概述Overview

EN

The FTX-1 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control over the low, mid and treble ranges in the voice waveform.

One group of settings may be utilized when the Speech Processor is Off, and an alternate group of settings when the Speech Processor is On (SSB mode only).

Parametric microphone equalizer function is activated only in LSB, USB, AM, AM-N, FM and FM-N modes.

FTX-1 内置独特的三段参数话筒均衡器，可对语音波形中的低音、中音和高音范围进行精确、独立的控制。

Speech Processor 关闭时可使用一组设置，Speech Processor 开启时可使用另一组设置（仅 SSB 模式）。

参数话筒均衡器功能仅在 LSB、USB、AM、AM-N、FM 和 FM-N 模式下生效。

技术提示 / TIP 请务必记住这是"两套参数"：Speech Processor 关闭时用 PRMTRC EQ1~EQ3，开启时用 P PRMTRC EQ1~EQ3（菜单名前面多一个 P）。日常如果只在 SSB 上开压缩器，你会发现"调完均衡器再开压缩器，声音又变回去了"——那不是没保存，而是切换到了另一组参数。两组都要按自己的耳朵分别调一遍。 There are two independent parameter sets: PRMTRC EQ1–EQ3 for Speech Processor OFF, and P PRMTRC EQ1–EQ3 (prefix "P") for Speech Processor ON. Adjust both groups separately.

26.2 参数话筒均衡器的设置Setup the Parametric Microphone Equalizer

EN
  1. Set the RF output power to minimum value. We recommend connecting a dummy load to one of the antenna jacks, and monitoring the signal on a separate receiver, to prevent interference to other users.
  2. Press and hold the [FUNC] knob.
  3. Touch [MIC EQ]. The Parametric Microphone Equalizer function is activated. To adjust the Parametric Microphone Equalizer with the Speech Processor engaged, activate the Speech Processor.
  4. Touch [MONI LEVEL].
  5. Rotate the [FUNC] knob to adjust the Monitor level.
  1. 把射频输出功率设为最小值。建议在天线接口之一接上假负载，并用另一台接收机监听信号，以免对其他用户造成干扰。
  2. 按住 [FUNC] 旋钮。
  3. 触摸 [MIC EQ]。参数话筒均衡器功能被激活。若要在 Speech Processor 投入工作的状态下调整均衡器，请先启用 Speech Processor。
  4. 触摸 [MONI LEVEL]。
  5. 旋转 [FUNC] 旋钮调整监听电平。
EN
  1. Select [OPERATION SETTING] → [TX AUDIO].
  2. Rotate the [FUNC] knob to find Menu items [PRMTRC EQ1 FREQ] through [PRMTRC EQ3 BWTH]; these parameters apply to the adjustment of the Parametric Microphone Equalizer when the Speech Processor is disabled. Menu items [P PRMTRC EQ1 FREQ] through [P PRMTRC EQ3 BWTH] apply to the adjustment of the Parametric Microphone Equalizer when the Speech Processor is engaged.
  3. Rotate the [FUNC] knob, or touch "<" or ">" on either side of the value to adjust a particular Menu item.
  4. Press and hold the PTT switch, and speak into the microphone while listening to the effect of the adjustments being made. Because the overall sound will change with each adjustment, make several passes through each adjustment area, to be sure that the optimum settings are achieved.
  1. 选择 [OPERATION SETTING] → [TX AUDIO]。
  2. 旋转 [FUNC] 旋钮找到菜单项 [PRMTRC EQ1 FREQ] 至 [PRMTRC EQ3 BWTH]；这些参数用于 Speech Processor 关闭时的均衡器调整。菜单项 [P PRMTRC EQ1 FREQ] 至 [P PRMTRC EQ3 BWTH] 用于 Speech Processor 投入工作时的均衡器调整。
  3. 旋转 [FUNC] 旋钮，或触摸数值两侧的 "<" / ">" 调整具体菜单项。
  4. 按住 PTT 开关，对着话筒讲话，同时监听调整效果。由于每调整一项整体声音都会变化，应在各个调整区间反复来回几遍，以取得最佳设置。
EN

The best way to hear the effects of the adjustments is to wear headphones (connected to the monitor receiver) while listening to the transmitted signal.

  1. When all adjustments are satisfactory, press the [FUNC] knob, or wait for about 3 seconds to save the setting.
  2. Press the [BACK] key several times to return to normal operation.

聆听调整效果的最佳方式，是戴上耳机（接在监听接收机上）来听发射出去的信号。

  1. 所有调整都满意后，按 [FUNC] 旋钮，或等待约 3 秒保存设置。
  2. 按几次 [BACK] 键返回正常操作。
避坑指南 · 调整发射音频时的干扰PITFALL · On-air adjustment 调整话筒均衡器需要长时间按住 PTT 讲话，如果直接对着天线发射，等于在频率上反复占用来回试音。请严格按手册要求：先把射频输出功率调到最小，接假负载，用另一台接收机（或请通联伙伴在旁监听）来听效果；监听时戴耳机，避免监听接收机的扬声器串音回授到话筒形成啸叫。 Adjusting the microphone equalizer requires long PTT key-down periods. Always reduce RF output power to minimum, use a dummy load, and monitor on a separate receiver with headphones to avoid acoustic feedback into the microphone.

26.3 启用参数话筒均衡器Activate the Parametric Microphone Equalizer

EN
  1. Adjust the MIC gain.
  2. Press and hold the [FUNC] knob.
  3. Touch [MIC EQ]. The Parametric Microphone Equalizer function is activated.
  4. Press the PTT switch on the microphone, and speak into the microphone in a normal voice level.

To cancel the Parametric Microphone Equalizer function, repeat steps 2 and 3 above, and choose "OFF" in step 3.

  1. 调整 MIC 增益。
  2. 按住 [FUNC] 旋钮。
  3. 触摸 [MIC EQ]。参数话筒均衡器功能被激活。
  4. 按下话筒上的 PTT 开关，以正常音量对着话筒讲话。

要取消参数话筒均衡器功能，重复上述第 2、3 步，并在第 3 步中选择 "OFF"。

Note that the two sets of parameters are independent: PRMTRC EQ1/2/3 (speech processor OFF) and P PRMTRC EQ1/2/3 (speech processor ON) have different defaults.

三个参数的含义Meaning of the three parameters

Center Frequency中心频率
三段中每一段的中心频率均可调整。The center frequency of each of the three bands may be adjusted.
Gain增益
可调整每一段内提升（或抑制）的量。The amount of enhancement (or suppression) within each band may be adjusted.
Q带宽
可调整均衡作用所覆盖的带宽。The bandwidth over which the equalization is applied may be adjusted.
HAM 实战 · SSB 常用话筒音色调整方向FIELD NOTE 社区里调 SSB 话筒音色的通行思路如下（社区经验，未证实，请配合监听接收机自行验证）：
① 先定"厚度"：LOW 段（PRMTRC EQ1，100–700 Hz）中心频率放在 300 Hz 附近、提升 +3 ~ +6 dB，可以让声音听起来更饱满有底气，但超过 +6 dB 容易发闷、糊，DX 弱信号通联时清晰度下降。
② 再定"穿透力"：MID 段（PRMTRC EQ2，700–1500 Hz）是语音可懂度的核心，1 kHz 附近提升 +2 ~ +4 dB 通常最能"穿透"噪声；如果对方说你的声音发尖或刺耳，就把中心频率往下移到 800 Hz 左右并收窄带宽。
③ 最后定"清晰度"：HIGH 段（PRMTRC EQ3，1500–3200 Hz）提升 +2 ~ +4 dB 可增加齿音清晰度，但过量会带来嘶声，配合射频噪底一起放大反而更难抄收。
④ 关于 Q（BWTH）：Q 值越大（带宽越窄）作用越集中，适合精准削减某个讨厌的共振峰；Q 值越小（带宽越宽）越像普通的低/中/高音色调。默认段的取值（表 26-1 中 LOW 为 10）属于较宽的作用带。
⑤ 流程建议：一次只动一个参数，每改一次就在监听接收机上听 10 秒，全靠耳朵收尾；把 Speech Processor 打开后务必再走一遍 P PRMTRC 那一组。 A common community approach for SSB microphone EQ (community-reported, unverified — always verify on a monitor receiver): set the LOW band near 300 Hz with a modest boost for body; treat the MID band around 1 kHz as the intelligibility core; add a small HIGH-band boost for articulation but avoid hiss; use a narrow Q to cut a specific resonance and a wide Q for general tone shaping. Change one parameter at a time, and repeat the whole process for the P PRMTRC group once the Speech Processor is on.
